Frequently Asked Questions
What safety features are built into the FSGM series controller?
It incorporates Overload Protection (OLP), Over-Voltage Protection (OVP), Auto-Output Current Protection (AOCP), and Temperature Shutdown (TSD).
What is the trigger point for overcurrent protection on the feedback pin?
If the voltage of Pin 3 reaches 6V, the overload protection triggers, which shuts down the FPS.
Does the device support various input AC voltages?
It operates on 230VAC ± 15% or can be configured for 85~265V using a voltage doubler.
How is the maximum continuous power assessed when designing an adapter?
The junction temperature limits the maximum output power, which must be accounted for in the design.
