Auxiliary Functions
Inhibit for Remote On/Off
The outputs may be enabled or disabled by means of a
logic signal (TTL, CMOS, etc.) applied between the inhibit
input i (pin 18) and pin 14 (S– or Vo1–). In systems with
several converters, this feature can be used to control the
activation sequence of the converters. If the inhibit function
is not required, connect the inhibit pin 18 to pin 14.

Sense Lines (Single-Output Models)
This feature allows for compensation of voltage drops
across the connector contacts and if necessary, across the
load lines. We recommend connecting the sense lines
directly at the female connector.
To ensure correct operation, both sense lines (S+, S–)
should be connected to their respective power outputs
(Vo+ and Vo–), and the voltage difference between any
sense line and its respective power output (as measured
on the connector) should not exceed the following values:

sense lines
Programmable Output Voltage (R-Function)
As a standard feature, the converters offer an adjustable
output voltage, identified by letter R in the type
designation. The control input R (pin 16) accepts either a
control voltage V
output voltage. When input R is not connected, the output
voltage is set to V

b) Adjustment by means of an external resistor:
