The DVS3 mk2 is the new smaller, lighter, higher power version of the  DVS3, offering more than twice the output power of the original DVS3. The exceptionally easy to understand user interface of the DVS3 is retained, allowing simple testing of complex voltage and loss of mains protection systems.
Equally at home in a commissioning, maintenance, or laboratory environment, the DVS3 mk2 is a truly flexible system. The DVS3 MK2 has been designed using the latest digital technology to generate a highly stable and accurate output with very low distortion. Each phase output is individually adjustable for voltage and phase angle. In addition, full control of frequency is available. Step changes of any quantity may be generated with automatic timing of the response of the relay under test.
The unit is controlled by a simple user interface with context sensitive menus. Values may be either typed in at the keypad or smoothly varied using a digital potentiometer.
