Auxiliary Functions
Primary Inhibit (Remote On / Off)
The inhibit input enables (logic low, pull down) or disables
(logic high, pull up or open-circuit) the output, if a logic signal
(TTL, CMOS) is applied. In systems consisting of several
converters, this feature may be used to control the activation
sequence by logic signals or to enable the power source to
start up, before full load is applied.
Table 6: Inhibit characteristics
The output response after enabling or disabling the output by
the inhibit input is shown in the figure below. See also Input
Data.

Output Voltage Adjust of V
The converters offer adjust of the voltage of powertrain 1.
Powertrain 2 can not be adjusted. The programming is
performed either by an external control voltage V
external resistor R
is limited to the values given in the table Electrical Output
Data.
With double output powertrains, both outputs are influenced
by the R-input setting simultaneously.

Note: If output voltages are set higher than V
currents should be reduced accordingly, so that the maximum
specified output power is not exceeded.
Note: R inputs of n converters with paralleled outputs may be
connected together, but if only one external resistor is used, its
