Notes:
1. Cross regulation is measured with the output being tested at 50% load. The second output is varied from 10% to 100%
load.
2. When measuring output ripple, it is recommended that an external ceramic capacitor (approx
10 µF) be placed from the +V
OUT
to the -V
OUT
pins for single output models; or from each output to common for dual
output models.
3. Transient recovery is measured to within a 1% error band for a load step change of 25%.
4. Short circuit protection is provided by a “hiccup mode” circuit.
5. These units should not be operated with a load under 5% of full load. Operation at no-load will not damage the unit, but
they may not meet all specifications.
6. These units should not be operated over +85°C. Exceeding +85°C may damage the unit.
7. It is recommended that a fuse be used on the input of a power supply for protection. See the Model Selection table above
for the correct rating.
Adapter Plate
Derating Curve
All models of the
MB1000x-xxERW
series are available mounted on an adapter
plate similar to the one pictured above. The adapter plate will allow the user to easily
mount the unit to a chassis or to a standard DIN rail. Please contact the factory for
more information.

Notes:
1. All units are rated for EN 55022 (CE/RE) class A without external components.
