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

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.

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.
