    Megger MPU690 Proving Unit 1001-561

    This product is also available in a safe isolation kit alongside the Megger TPT320 Voltage Tester for just £89.00! Click here to find out more.

    The new Megger MPU690 Proving Unit provides a portable, battery powered voltage source that can verify the correct functioning of a voltage tester. The MPU690 safely generates a range of voltages from 50V to 690V in five steps. When switched on the MPU 690 proving device will initially generate 690 volts and after a short period will slowly ramp down through each voltage step until the unit switches off. Each individual voltage step is indicated by an LED with one for indicating power that also indicates exhausted battery. The Megger MPU690 will automatically power up when voltage tester probes are inserted into the output terminals, generating a 50Hz output voltage which simulates the AC mains supply.

    Megger MPU690 Proving Unit Features:

    • 5 stepped nominal output voltages from 50 - 690 volts
    • Automatic operation
    • High output power suitable for test lamps
    • Extended battery life
    • Magnetic base
    • Rugged case

    The Megger MPU690 proving unit has a generous output rating and the spacing of the output terminals allows it to verify the correct operation of voltage detectors that use a lamp for operation (John Drummond test lamps). It is also the perfect proving unit for the new Megger TPT210 and TPT220 voltage indicators. Despite the proving device's high output it has an exceptionally good battery life.

    you can never really go wrong with megger testing equipment. the proving unit is a bit expensive but its awsome very well made and ive seen a few others but this one is definalty the best on the market i think anyway. the LED display looks nice its even got a magnet on the back to hang on the board covers if you wanted to carry out a quick test which i found handy but anyways really happy.
