Notes:
1. Transient recovery is measured to within a 1% error band for a load step change of
75% to 50% to 25%.
2. Operation at no-load will not damage these units. However, they may not meet all
specifications.
3. 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.
4. 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.

To help meet EN55022 conducted emissions requirements, a simple Pi filter
should be added externally to the input of the converter. Recommended
components (C
1
, C
2
& L
1
) are shown in the diagram above.These compo-
nents should be mounted as close to the module as possible.
To meet the requiremets of EN61000-4-4, EN61000-4-5 and EN61000-4-6,
an external capacitor is required. It is recommended that the value shown in
the figure above (C
3
) be used.
A positive logic Remote On/Off input (Pin 6) can be used
to control the converter. An open collector (or open
drain) switch (Q
1
) is placed between the control input
(Pin 6) and the -V Input (Pin 2).
If not being used, the control input should be left open.
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. For
noise sensitive applications, the use of 3.3 µF capacitors (as shown in the
diagram above) will reduce the output ripple.

B2000RU
Series
A simple external circuit may be used to adjust Vout on
single output models. To adjust the output DOWN, con-
nect 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. Resistor values are given in the chart below.
For UP/Down trimming capability, connect a 10 kW poten-
tiometer 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.
