Notes:
1. When measuring output ripple, it is recommended that an external 1.0 µF ceramic capacitor
be placed from the +Vout pin to the -Vout pin for single output units and from each output to
common for dual output units.
2. Transient recovery is measured to within a 1% error band for a load step change of 75% to
100%.
3. Operation at no-load will not damage these units. However, they may not meet all specifications.
4. Dual output units may be connected to provide a 10 VDC, 24 VDC or 30 VDC output. To do this,
connect the load across the positive (+Vout) and negative (-Vout) outputs and float the output
common.
5. With the addition of a simple input Pi filter, the unit should meet the conducted emissions
requirements of EN55022 class A. Typical component values would be 2.2 µF/100V for the two
capacitors and 12 µH for the inductor. The filter components should be mounted as close to
the unit as possible.
6. It is recommended that a fuse be used on the input of a power supply for protection. See the
table above for the correct rating.

Output Trim
(Single Output Models)
A simple external circuit may be used to
adjust the converter output. To adjust the
output DOWN, connect a 5%, 3W resistor
between the plus output pin and the Vout
trim pin. To adjust the output UP, connect a
5%, 3W resistor between the minus output
pin and the Vout trim pin.
For UP/Down trimming capability, con-
nect a 10 kW potentiometer between
the plus and minus outputs with the
wiper arm connected to the Vout trim pin.
