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.

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.

Care should be taken that the maximum

output power of the unit does not exceed

the maximum rating.
