High precision thermal relay calibrator

High precision thermal relay calibrator

Function Introduction:

A new generation of testing instrument developed by collecting feedback information from users across the country and years of practical experience, mainly used for setting and verifying various thermal relays and motor protection devices. Due to its reasonable design, easy operation, and high output power, it is widely used in electrical testing sites of enterprises such as power systems, railways, petrochemicals, metallurgy, and mining.

High precision thermal relay calibrator

Product nickname:

Three phase thermal relay tester, electronic thermal relay calibrator, thermal relay calibrator, thermal relay tester, motor protector tester.

Product features:

1. The three-phase output 0-50A-500A three-phase instrument can be tested simultaneously or adjusted in phases. And it can synchronously record the action time with automatic discrimination of normally closed contacts.

2. Adopting a multifunctional digital LED display instrument, the reading is intuitive and the accuracy is high.

3. Adopting a beautiful and elegant aluminum alloy chassis with a flip cover, the chassis is equipped with handles on both sides for on-site movement.

4. The use of imported components increases the load capacity of the instrument and provides a more complete electrical protection circuit, which can be connected in series with several devices for simultaneous verification. Greatly improved verification efficiency.

5. Increased the output current to adapt to commonly used current settings and increased it to multiple output currents to adapt to the detection of various commonly used electrical appliances.

Other structures have also been improved accordingly, with more complete functions, providing convenience for use, simplifying operating procedures, and making them more suitable for on-site use.
