Auxiliary Functions
i Inhibit for Remote On and Off
Note: With open i input: Output is disabled (
Vo = 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
example, 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:
Output
Response.

R-Control for Output Voltage Adjustment
Note: With open R input,
Vo Vo nom.
As a standard feature, single-output models offer an
adjustable output voltage identified by letter R in the type
designation.
The output voltage
Vo1 can either be adjusted with an
external voltage (
Vext) or with an external resistor (R1 or R2).
The
adjustment range is approximative 0 to 110% of
Vo nom. For output voltages Vo > Vo nom, the minimum input
voltage according to
Electrical Input Data increases
proportionally to
Vo/Vo nom.

Caution: To prevent damage,
Vext should not exceed
8 V, nor be negative.
Caution: To prevent damage,
R2 should never be less
than 47 k
Ω.
Note: R inputs of n models with paralleled outputs may be
paralleled, too, but if only one external resistor is to be
used, its value should be R1/n, or R2/n respectively.
