Martindale PD440SRD 440V Advanced Proving Unit

The Martindale PD440SRD 440V Advanced Proving Unit is suitable for use in both domestic and commercial applications for proving situations up to 440V. The PD440SRD has push button functionality which allows for switchable AC/DC output modes. Offering four proving rages of 440V, 230V, 150V and 50V.

The PD440SRD is the ideal proving unit for low and high impedance voltage indicators and has colour coded voltage out put to 440V, and AC or DC output which is selectable by using the push button switch. Stepped voltage LEDs with thresholds that are matched to most voltage indicators and two pole testers.

The PD440SRD offers High/Low Z compatibility and is suitable for multimeters, multifunction testers, 4-500V voltage testers and Drummond test lamps.

With its over moulded low profile design and included MG3 high strength magnetic hanger, the PD440SRD also a low battery LED and auto power off function, helping preserve the battery life.
