1. Introduction
This application note describes the features and functions of Intronics
power’s AC100 series of open frame, Isolated AC-DC Converters.
These are highly efficient, reliable and compact, high power density,
single output AC/DC converters. Ultra-high efficiency operation is
achieved through the use of synchronous rectification and drive control
techniques. The modules are fully protected against short circuit and
over-voltage conditions. Intronics power’s world class automated
manufacturing methods, together with an extensive testing and
qualification program; ensure that all AC100 series converters are
extremely reliable.

3. General Description
A block diagram of the AC100 series converter is shown in Figure 1.
Extremely high efficiency power conversion is achieved through the use
of synchronous rectification and drive techniques. Essentially, the
powerful AC100 series topology is based on an isolated synchronous
forward converter. The control loop is optimized for unconditional
stability, fast transient response and a very tight line and load
regulation. The output voltage can be adjusted from +5% to –5%, using
a variable resistor.

5. Main Features and Functions
5.1 Operating Temperature Range
5.4 Over Voltage Protection
Intronics power’s AC100 series converters highly efficient converter
design has resulted in its ability to operate ambient temperature
environment (0℃ to 40℃). Due consideration must be given to the de-
rating curves when ascertaining maximum power that can be drawn
from the converter. The maximum power drawn is influenced by a
number of factors, such as:
All different voltage models have a full continuous over voltage
protection. The power module will supply up to 150% of rated voltage.
In the event of an over voltage converter will go into a hiccup mode
protection.
5.5 V-Sense
•
•
•
Input voltage range.
V-sense measures the use as outputting the voltage.
The maximum length of the sense lines is 1200mm.
Output load current.
These can be effective heat sinks for the converter.
The min gauge wire that can be used 26AWG.
If does not use and needn't need to join .
5.2 Output Voltage Adjustment
The output voltage on all models is in the range from +5% to –5%
6. Safety

CB Approval
TUV Approval
UL Approval
5.3 Over Current Protection
All different voltage models have a full continuous short-circuit
protection. The unit will auto recover once the short circuit is removed.
To provide protection in a fault condition, the unit is equipped with
internal over-current protection. The unit operates normally once the
fault condition is removed. The power module will supply up to 150% of
rated current. In the event of an over current converter will go into a
hiccup mode protection.

Please reserve 4mm space from the surfaces and the sides of PCB, especially from the solder surface, 8mm space is necessary. If the space is not enough, the
specification of insulation and withstand will not be satisfied.
FG should be connected to the earth terminal of the apparatus. If not, the conducted noise and output noise will increase.
