The KRS25F-03 from Kaga Electronics USA is a versatile AC/DC power supply module designed for ITE (Commercial) applications. This open-frame converter operates with an input voltage range of 85 to 264 VAC at 47 to 63 Hz, delivering a stable 3.3VDC output at up to 6A, for a total power of 25W.
Key electrical specifications include an efficiency of 69% at full load, a voltage adjustment range of ±10%, and an output voltage accuracy of ±5%. It also features over-current protection that automatically recovers and thermal shutdown.
Designed for easy integration, the KRS25F-03 utilizes a Through Hole mounting type and comes in a 5-DIP Module package. It operates within an ambient temperature range of 0°C to 70°C, with derating applied at higher temperatures. The unit meets various safety and EMI standards, including UL60950, CE, FCC Part 15 Class B, and EN55022 Class B.
The input voltage range is 100 to 230 VAC, with an absolute range of 85 to 264 VAC.
The output voltage is 3.3 VDC.
The output current is 6 A.
It uses a 5-DIP module with through-hole mounting.
The operating temperature range is 0°C to 70°C with derating.
It includes over-current protection that activates above 105% load with automatic recovery.
Primary-secondary isolation is 3000 VAC, primary-ground is 2000 VAC, and secondary-ground is 500 VAC.
