Martindale PD440S Proving Unit

Martindale PD440S 440V AC Proving Unit

Safe electrical working requires the use of a voltage indicator that has been proven with a suitable proving device before and after use to ensure the instrument is working correctly in accordance with the Electricity at Work Regulations.

The Martindale PD440S voltage output is matched to the VI13800, the MTL10 and MTL20 Drummond test lamps and all other 440V voltage indicators and testers.

The PD440S features a tough overmoulded low profile case and comes with an MG3 magnetic hanger (excluding kits). It is fast and easy to use, instantly supplying the test voltage for both high and low impedance voltage indicators, test lamps and meters.

It’s good practice to match the output voltage of the proving unit with the voltage range of the instrument to be proved.
