Voltage and Current Amplifier

The powerful three-phase relay test set MP3000A is designed for multipurpose field test and commissioning application. All types of protection relays, including electro-mechanical, solid state and modern microprocessor based, can be easily tested with our automatic relay testing software. High accurate voltage and current source makes it easy to test energy meeters and transducers too.  The distinguishing feature of voltage and current amplifier is the load-adaptive characteristic, which significantly increase the amplifier effeciency, resulting in both high output power and longer output time at the same time.
