Operation: Applying “1”or leaving open will turn the power supply ON. For constant operation, leave this pin unconnected. Applying “0” or shorting this pin to its return line will turn the power supply OFF. Signal Type: 5V TTL or dry contact (open/short). Return line: This signal is referenced to Input RTN pin. Sync signal Description: The Sync signal can be used to allow the power supply switching frequency to synchronize with a system clock. Operation: Apply a square wave clock with frequency in the range of 250 kHz ± 10 kHz and duty cycle of 50% ± 10%., TTL level. If not required, leave open. The power supply will work at 250 kHz ± 10 kHz (internal clock). Signal Type: 5V TTL Return line: This signal is referenced to Sync RTN pin. Sense Description: The Sense is used to compensate for voltage drop across the output wires by sensing the voltage at the load and correcting the increasing the output voltage accordingly, to provide the desired voltage at the load's terminals. Operation: Connect the Sense pin to the positive load terminal, and the Sense RTN pin to the negative (return) load terminal. The sense compensation is typically limited to 5% or 0.5V – the lesser of the two. If not used, connect Sense directly to Output pins, and the Sense RTN pin directly to the Output RTN pins. IMPORTANT: to avoid damage to the converter and/or the load - DO NOT LEAVE THE Sense/Sense RTN PINS UNCONNECTED. Typical Connection Diagram
