AC-DC Power Supplies

GCS265 Series

Signals & Controls

Characteristic

Notes & Conditions

Open collector pin 6 referenced to -ve sense pin 2 of J4.

Provides ≥2 ms warning of loss of output from AC failure.

Power Fail (AC-OK)

Standby Supply

Remote Sense

5 VDC/3.0 A Isolated supply present when AC applied.

Compensates for 0.5 V total voltage drop

The inhibit lo (pin 4), should be pulled below 0.4 V to switch V1 & Vfan off. Open circuit or >4 V to

switch on (see fig. 7)

Inhibit

Remote On/Off

With the inhibit lo (pin 4) pulled low as detailed above, connecting inhibit hi (pin 5) to inhibit lo (pin 4)

will enable V1 & V fan output. (see fig. 8)
