5 stepped nominal output voltages
High output power suitable for test lamps
Extended battery life
Good practice requires that two pole voltage detectors are proved to be functioning correctly on a known voltage source, both before and after they have used to verify that a circuit is not live.
The Megger MPU690 proving unit provides a portable battery operated voltage source that can verify the correct functioning of a two pole voltage detectors.
The generous output power rating and the spacing of the output terminals allows the MPU690 to verify the correct operation of voltage indicators that utilise a lamp for operation. Although the unit has a high output the unit has exceptionally good battery life.
The rugged case of the MPU690 features a magnetic base for convenient use.
N.B. The MPU690 is not recommended for use with multi- meters.
