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.
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)
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)
