Notes & Conditions

Remote Sense

Compensates for 0.5 V total voltage drop

Remote On/Off (-R models)

(Standard on GCS350 models)

Inhibit

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. 6)

Enable

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. 7)
