Additional Notes

Ultra-Low Vf Input Reverse Polarity protection: Protects against input misconnections or unanticipated polarity reversal of any duration. Clampless design eliminates need for external diodes or fuses.

Input Under Votlage Lockout: User programmable UV lock with hysteresis to hut operation at line inputs under selected limit.

Remote Sense: Auto adjusts output voltage for load lead losses

Output Soft Start: User programmable output turn on delay ramp.

Full Load Range Voltage Regulation: Regulates down to zero applied load.

Dual Mode Overcurrent Short Circuit Protection: Current mode control pulse by pulse and cyclic mode overcurrent protection.

Internal OverVoltage Protection: Overvoltage protected for internal (open control loop) fault.

Built in EMI filter: Input filer, output filtering smooth ripple and attenuates noise spikes.
