Description

QUINT DC/DC converter – maximum system availability

Features

from SFB technology

–

Wide-range voltage input

Galvanic isolation

Reverse polarity protection

Preventive function monitoring

Reliable starting of difficult loads with POWER BOOST

static power reserve

Compact DC/DC converters from the new QUINT POWER

generation maximize your system availability. With SFB

technology (Selective Fuse Breaking Technology), 6-fold

nominal current for 12 ms, it is possible to trigger even stan-

dard circuit breakers reliably and quickly. Faulty current

paths are switched off selectively, the fault is located, and

important system parts remain in operation. Comprehensive

diagnostics are provided through constant monitoring of the

input voltage, output voltage and output current. Preventive

function monitoring visualizes critical operating states and

indicates them to the controller before errors can occur.

–

Fast tripping of standard circuit breakers with dynamic

SFB technology power reserve

High MTBF > 761000 h (40°C)

Flexible use

The application fields for DC/DC converters are numerous

–

Adjustable output voltage

Can be used in Class I, Division 2, Groups A, B, C, D

(Hazardous Location) ANSI-ISA 12.12

–

Changing the voltage level

Refreshing the output voltage for constant voltage at

the end of long cables

–

Setup of independent supply systems by electrical iso-

lation

Connection to the input voltage is established via the screw

connectors on the DC input screw connection.

The DC/DC converter converts a DC voltage of 18 ... 32 V

into adjustable, regulated, and electrically isolated output

voltage.

Assembly:

Position the module with the DIN rail guide on the upper

edge of the DIN rail, and snap it in with a downward motion.

The DC/DC converter requires an input voltage of 18 V. Dur-

ing operation, this can drop down to 14 V, then observe de-

rating.

10.1 Rotated mounting position (270° Y-axis)

A rotated mounting position can be achieved by mounting

the module onto the DIN rail at a 270° angle. Mount the DIN

rail adapter (UTA 107/30) as shown in the figure. No addi-

tional assembly material is required. Mounting screws:

Torx® T10 (0.8 Nm ... 0.9 Nm tightening torque).

11.1 Protection of the primary side

Device installation must be carried out according to the reg-

ulations in EN 60950.

For device protection, there is an internal fuse. Additional

device protection is not necessary.

An internal fuse is provided for device protection. Additional

device protection is not required.

The connecting cables on the primary side should have

large cross sections to keep the voltage drops in the cables

as low as possible.

Figure 5

Rotated mounting position (270° Y-axis)

NOTE: Module can become damaged

Other mounting positions are also possible.

Always observe position-dependent derating.

If an internal fuse is triggered, there is a device

malfunction. In this case, the device must be

inspected in the factory.

12 Output

13 Output characteristic curve

Connection of the output voltage is established via the

screw connectors on the DC output screw connection.

The output voltage can be set on the potentiometer.

The device functions according to U/I characteristic curve

with static POWER BOOST power reserve shown in the il-

lustration. At ambient temperatures of less than 40°C, the I

_BOOSTis even permanently available. It is also available at

higher temperatures for several minutes.

In the event of a secondary-side short circuit or overload, the

output current is limited to I_BOOST. In this case, the device

does not switch off but supplies output current continuously.

The secondary voltage is then reduced until the short circuit

is eliminated. The U/I characteristic curve with the POWER

BOOST power reserve ensures that high inrush currents of

capacitive loads in the primary circuit can be supplied.

12.1 Protecting the secondary side

The device is electronically short-circuit-proof and idling-

proof. In the event of an error, the output voltage is limited. It

must be ensured that all output cables are dimensioned or

separately protected according to the maximum output cur-

rent.

The connecting cables on the secondary side should have

large cross sections to keep the voltage drops in the cables

as low as possible.

14 SFB technology

If conditions cannot be observed, SFB tech-

nology can be deactivated.

SFB (Selective Fuse Breaking) technology reliably switches

off faulty current paths in the event of a short circuit. In this

case, it supplies up to six times the nominal current for 12

ms. SFB technology therefore reliably triggers standard cir-

cuit breakers. Faults are located reliably and important sys-

tem parts remain in operation.

14.3 Deactivating SFB technology

The DC/DC converter is equipped with an additional SFB

switch which can be used to deactivate SFB technology.

The SFB switch is located on the top side of the housing and

is accessible for suitable tools, such as a small screwdriver

through the vents.

14.1 Circuit breaker tripping characteristics

Typically, a circuit breaker trips within 3 ... 5 ms. Fast

enough to avoid voltage drops of parallel connected loads.

Make sure that the source to be supplied is able to de-

liver a corresponding current pulse to supply the DC/DC

converter. For example, this can be achieved by up-

stream connection of a QUINT SFB power supply (see

accessories) or suitable battery capacity.

Ensure the lowest possible cable impedance at the in-

put of the DC/DC converter by using short cable lengths

and large cable cross sections.

Activating/deactivating SFB technology must

only be performed when the DC/DC converter

is switched off.

Observe the maximum distance between the

source to be supplied and the DC/DC convert-

er.

The following parameters are the basis for calculation:

–

Circuit breaker from Siemens, B and C characteristics

(e. g., B6: 5SY6106-6)

–

B characteristic: electromagnetic tripping of the circuit

breaker at the latest at (5-fold rated current) x (correc-

tion factor 1.2 at 0 Hz) = 6-fold rated current

–

C characteristic: electromagnetic tripping of the circuit

breaker at the latest at (10-fold rated current) x (correc-

tion factor 1.2 at 0 Hz) = 12-fold rated current

–

Ambient temperature: +20 °C

The internal resistances of the circuit breakers are con-

sidered.

–

In addition to short circuit current, the relevant power

supply unit supplies half of the nominal current for paths

connected in parallel.

15.1 Active switching output “DC OK”

15 Signaling

In normal operation of the power supply unit, the DC output

signal (U_OUT> 0.9 x U_N) is between the "DC OK" and "-"

connection terminal blocks and can be loaded with a maxi-

mum of 20 mA. The DC OK signal output switches from "ac-

tive high" to "low" when there is a drop of output voltage of

more than 10%.

The DC OK signal is decoupled from the power output. This

makes it impossible for devices connected in parallel to act

as an external power supply.

The active DC OK signal output, active POWER BOOST

signal output and the active U_INOK signal output are avail-

able for function monitoring. In addition, the DC OK LED,

BOOST LED and the U_IN< 19.2 V LED enable the evalua-

tion of the power supply directly at the local site.

blocks "U_IN> 19.2 V” and “-” and can carry a maximum of

20 mA. The U_IN> 19.2 V signal output indicates a low input

voltage by switching from “active high” to “low”.

16.2 Voltage-dependent derating

The nominal input voltage of 24 V DC is divided into the

areas of starting and operation. The DC/DC converter re-

quires at least 18 V DC for cold starting, whereby the input

voltage can sink to 14 V DC during operation. The device

only switches off under this limit. The upper voltage limit is

32 V DC for both starting and operation.

minal blocks 13 and 14 and can be loaded with

max. 100 mA at max. 30 V AC/DC. The relay contact signal-

izes a drop of output voltage of more than 10% by opening

the N/O contact.

16.3 Position-dependent derating

+

PLC Digital Input

The power supply units can be snapped onto all DIN rails ac-

cording to EN 50022-35. It should be mounted horizontally

(with the input terminals facing downwards). When installing

in a different position, derating should be adhered to.

16 Derating

16.1 Temperature-dependent derating

With an ambient temperature of up to +40°C, the device

supplies the continuous output current of I_BOOST. The de-

vice can supply a nominal output current of I_Nwith ambient

temperatures of up to +60°C. In the case of ambient temper-

atures above +60°C, the output current must be reduced by

2.5% per Kelvin increase in temperature. The device does

not switch off at ambient temperatures of +70°C or thermal

overload. The output capacity is reduced as far as neces-

sary to provide device protection. After it has cooled down,

the output capacity is increased again.

17.3 Redundant operation

17 Other operating modes

Redundant circuits are suitable for supplying systems,

which place particularly high demands on operational

safety. If a fault occurs in the primary circuit of the first power

supply unit, the second device automatically takes over the

complete power supply without interruption, and vice versa.

For this purpose, the power supply units to be connected in

parallel must be large enough to ensure that the total current

requirements of all loads can be fully met by one power sup-

ply unit. External decoupling diodes are required for 100%

redundancy!

17.2 Parallel operation

−

Devices of the same type can be connected in parallel to in-

crease both redundancy and power. No further adjustments

are necessary for the default setting.

To ensure symmetrical load distribution, it is recommended

that all cable connections from the power supply unit to the

busbar are the same length and have the same cross sec-

tion!

Depending on the system, a protective circuit should be in-

stalled at each individual device output (e.g., decoupling

diode or DC fuse) for parallel connection of more than two

power supply units. This prevents high return currents in the

event of a secondary device fault.

17.4 Increasing power

For n parallel connected devices, the output current can be

increased to n x I_N. Parallel connection for increasing power

is used when extending existing systems. A parallel connec-

tion is recommended if the power supply unit does not cover

the current consumption of the most powerful load. Other-

wise the loads should be divided on individual devices inde-

pendent from each other.
