Auxiliary Functions
i Inhibit for Remote On and Off
Note: With open i input: Output is disabled (
Uo = off).
The outputs of the module may be enabled or disabled by
means of a logic signal (TTL, CMOS, etc.) applied between
the inhibit input i and the negative pin of output 1 (Vo1–). In
systems with several units, this feature can be used, for ex-
ample, to control the activation sequence of the converters.
If the inhibit function is not required, connect the inhibit pin
2 to pin 23 to enable the outputs (active low logic, fail safe).
For output response refer to:
Hold-up Time and Output Re-
sponse.
