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
18 to pin 14 to enable the outputs (active low logic, fail
safe). For output response refer to:
Hold-up Time and Out-
put Response.

Sense Lines
(Only for single output units 5.1 V, 12 V, 15 V, 24 V)
This feature enables for compensation of voltage drops
across the connector contacts and if necessary, across the
load lines. If the sense lines are connected at the load
rather than directly at the connector, the user should ensure
that
Uo max (between Vo1+ and Vo1–) is not exceeded. We
recommend connecting the sense lines directly at the fe-
male connector.
For further information, please refer to:
Application Notes .
To ensure correct operation, both sense lines (S+ and S–)
should be connected to their respective power outputs
(Vo1+ and Vo1–) and the voltage difference between any
sense line and its respective power output pin (as meas-
ured on the connector) should not exceed the following val-
ues:

If the output voltages are increased above
Uo nom via R-in-
put control, option P setting, remote sensing or option T, the
output currents must be reduced accordingly so that
Po nom is not exceeded.
Important: The output terminals Vo1+ and Vo1– must
always be connected to the load before connecting the
sense lines S+ and S–, otherwise the unit will be dam-
aged.
