a) Adjustment by means of an external resistor
Rext:
Programming of the output voltage by means of an exter-
nal resistor
Rext is possible within a limited range of
100...105% of
Uo nom. Rext should be connected between
the Trim pin and Vi–. Connection of
Rext to Vi+ may dam-
age the converter. The following table indicates suitable
resistor values for typical output voltages under nominal
conditions (
Ui nom, Io = 0.5 Io nom), with either paralleled
outputs or equal load conditions on each outputs.
b) Adjustment by means of an external voltage source
Uext.
For external output voltage programming in the range
75...105% of
Uo nom a (0...20 V) source Uext is required,
connected to the Trim pin and Vi–. The table below indi-
cates typical
Uo versus Uext values under nominal condi-
tions (
Ui nom, Io = 0.5 Io nom), with either paralleled outputs
or equal load conditions on each output. Applying a con-
trol voltage >20 V will set the converter into a hiccup
mode. Direct paralleling of the Trim pins of units con-
nected in parallel is feasible.

Auxiliary Functions
Shut Down Function
The outputs of the converters may be enabled or disabled
by means of a logic signal (TTL, CMOS, etc.) applied to the
shut down pin. If the shut down function is not required then
it should be left open-circuit.
Converter operating:
2.0...20 V
Converter shut down:
–10...0.7 V
Adjustable Output Voltage
– R input for single output units and -0503- types
– Trim input for double output units
As a standard feature, the IMS 15 single and double output
units offer adjustable output voltage(s) by using the control
input R or Trim. If the control input is left open-circuit the out-
put voltage is set to
Uo nom. For output voltages Uo > Uo nom,
the minimum input voltage
Ui min (see: Electrical Input Data)
increases proportionally to
Uo/Uo nom.
Single output units and -0503- types:
The R input is referenced to the secondary side of the con-
verter. Adjustment of the output voltage is possible by
means of either an external resistor or a voltage source.
a) Adjustment by means of an external resistor
Rext:
Depending upon the value of the required output voltage,
the resistor shall be connected
either: Between the R pin and Vo– to achieve an output
voltage adjustment range of approximately
Uo = 80...100% Uo nom.

b) Adjustment by means of an external voltage
Uext be-
tween Vo– and R pins.
The control voltage range is 1.96...2.62 V and allows for
an adjustment in the range of approximately 80...105%
of
Uo nom.

Attempting to adjust the output below this range will
cause the converter to shut down (hiccup mode).
Note: Applying an external control voltage >2.75 V may
damage the converter.
Double output units (except -0503- types):
The Trim input is referenced to the primary side. The figure
below shows the circuit topology. Adjustment of the output
voltage is possible by means of either an external resistor
Rext in the range of 100...105% of Uo nom or an external volt-
age source in the range of 75...105% of
Uo nom.
