MEGGER MPU690 PROVING UNIT

Good safety 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.

MEGGER MPU690 PROVING UNIT Features:

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

    MEGGER MPU690 PROVING UNIT

    Two pole voltage testers generally have a self testing function to check the unit is working and does not have exhausted batteries. This test does not necessarily indicate the instrument will safely show a voltage measurement, particularly voltages in excess of 50 volts. Two pole voltage testers are recommended to be tested with a known live voltage source prior to making a voltage measurement on a circuit.

    The Megger MPU690 proving unit provides an alternative portable battery operated voltage source that can verify the correct functioning of a voltage tester.

    The Megger MPU690 safely generates a range of voltages from 50 to 690 volts in five steps. At switch on, the unit initially generates 690 volts then after a short period, slowly ramps down through each voltage step until the device switches off.

    The individual voltage steps are indicated by an LED with a power indicator LED that also indicates an exhausted battery. The MPU690 features automatic power on when voltage tester probes are inserted into the output terminals, generating a 50 Hz output voltage which simulates the AC mains supply

    MEGGER MPU690 PROVING UNIT APPLICATIONS:

    The generous output power rating and the spacing of the output terminals allows the MEGGER 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 multimeters.
