Notes:

Derating Curve

1. When measuring output ripple, it is recommended that an external ceramic

capacitor (approx 1 µF to 10 µF) be placed from the +Vout to the -Vout pins.

2. The remote On/Off control is referenced to ground. It is recommended that

connection to the pin be made through a 1kΩ resistor and diode (1N4148).

If it is not used, the control pin should be left open.

3. These units should not be operated with a load under 10% of full load. Operation

at no-load will not damage the unit, but they may not meet all speciﬁcations.

4. These converters are speciﬁed for operation without external components. How-

ever, in some applications the addition of input/ouput capacitors will enhance

stability and reduce output ripple.

For applications requiring very low output noise levels, a simple LC ﬁlter should

be effective.

5. These units should not be operated over +85°C (see derating curve). Exceeding

+85°C may damage the unit.

6. It is recommended that a fuse be used on the input of a power supply for protec-

tion. See the Model Selection table above for the correct rating.

Remote On/Off Remote On/Off

On single output units, a simple external

circuit may be used to adjust the converter

output. To adjust the output DOWN, con-

nect a 5%, 3W resistor between the plus

output pin and the Vout trim pin. To adjust

the output UP, connect a 5%, 3W resistor

between the minus output pin and the

Vout trim pin.

Mechanical Notes:

• All dimensions are typical in

inches (mm)

• Tolerance x.xx = 0.01 ( 0.25)

For UP/Down trimming capability, connect

a 10 kW potentiometer between the plus

and minus outputs with the wiper arm con-

nected to the Vout trim pin.
