- Open-Frame Type 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.

- Main Features and Functions
5.1 Operating Temperature Range
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:
- Input voltage range.
- Output load current.
- These can be effective heat sinks for the converter.
5.2 Output Voltage Adjustment
The output voltage on all models is in the range from +5% to –5% but can't exceed the watt value of the products .
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.
5.4 Over Voltage Protection
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
V-sense measures the use as outputting the voltage. The maximum length of the sense lines is 1200mm. The min gauge wire that can be used 26AWG. If does not use and needn't need to join . 6. Safety CB Approval TUV Approval UL Approval 7. Applications

Annotations：All models height does not exceed 34mmMAX . Figure 11. AC100 Mechanical Outline Diagram
Please reserve 4mm space from the surfaces and the sides of PCB, especially from the solder surface, 8mm space is necessary. I f 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. Page 13
