ISOLATION CHARACTERISTICS
Internal thermostat protects the power supp ly against excessive temperature. Automatic recovery.
Outputs shut down at 125% of nominal; AC input must be recycled to restore operation.
12V output: 110 to 130% of Imax, hiccup mode current limit; automatic recovery. Long-term fail condition
shall not cause damage to PSU.

Description
This signal is used to detect the presence of output voltage. This signal goes high when input power is applied and output voltage is more
than 85% of nominal 12.0 VDC output. Signal type: TTL-compatible, with 2.43K pull-up resistor to +5V.
Active low input to enable +12VDC output of power supply. For normal operation, short to - Sense.
Positive side of Remote Sense input.
Negative side of Remote Sense input.
+5V standby.
Single-wire current-share connection.
10mA min. When PG is high, Pin 1 of J2 shall go high to illuminate external GREEN LED. When PG is low, Pin 3 of J2 shall go high to
illuminate external YELLOW LED.
