This T&R DVS3 MKii Relay Test System has been tested and is working, but please note the screen defects in the photographs.

Missing side panel and the lcd screen has dead pixels - See photos.

Missing Pelicase.

The T & R DVS3 Mk2 offers 3 phase relay testing at a maximum current of 335mA.

It features an easy-to-use interface to allow simple testing of complex voltage and loss of mains protection systems. 

The DVS3 is ideal for a wide range of industries including commissioning, laboratory and maintenance.

It uses the latest technology creating a stable and accurate output with very low distortion.

Individual phase output is adjustable for both voltage and phase angle, with full control of frequency.

Step changes of any quantity can be generated with automatic response timing of the relay under test.

In terms of control, the user interface is simple with context sensitive menus.

An external keyboard is included for typing values in, or they can be smoothly varied using a digital potentiometer.

The LCD is backlit, with menu options having a dedicated button on the panel.

This simple layout enables quick access for adjusting voltage, phase and frequency.

Both phase to phase and phase to neutral voltage are simultaneously displayed, with frequency and phase information.

In addition a graphical vector diagram is shown, along with the state of the two contact inputs.

The DVS3 is suited to testing G59 protection, including loss of mains protection.

Along with vector surge and dt/df relays, the DVS3 is also ideal for testing the following:

Under and over frequency relays

Under and over voltage relays

Synchronising relays

dt / df & ROCOF relays

Transducers

We ship via Royal Mail and Parcelforce for all orders, and pride ourselves on our fast and efficient service.

All our static-sensitive components and parts are shipped in specialised anti-static bubblewrap and carefully packaged.

We sometimes use generic images for our items - the one you receive will be the one described, and/or similar to the one shown in the photos. Due to multiple quantities being stock under the same listing, the locations of marks and scratches may differ.
