l Three-Phase Compatible Single-Phase There are 3 phase voltage outputs and 2 phase current outputs, which can reach AC120V/80VA and AC50A/450VA respectively. The 2 phase currents can be paralleled as single phase output, reaching AC80A/900VA. New-type high-power modular high fidelity DC power amplifier is adopted in output units, which can directly output AC/DC voltage or current with variable frequency and phase angle. 0~6th harmonic can be overlapped. Accuracy and reliability is high.
l Independent Operation Photoelectric rotary mouse and large LCD screen is installed on the panel for convenient operation, with total Chinesized interface. Fit for most verification test on-spot.
l Large LCD Screen 320x240 lattice screen and high-definition graphical LCD are employed, with whole operation process displayed. Operation interface and test result are displayed in Chinese clearly and intuitively.
l Foolproof Operation Advanced photoelectric rotary mouse is used, which largely simplifies operation structure and realizes convenient and easily-grasped operation. Instant and permanent faults (such as single phase grounding, two-phase short-circuit) can be simulated factually. Various kinds of relays and microcomputer protection unit can be verified.
l Perfect Self-Protection Not only reasonable heat dissipation structure, multiple perfect and reliable protection are also adopted, such as power soft-start, thermal protection, output time limit, current/voltage amplitude limit, voltage short circuit lockout, current open circuit indication, fault self-diagnosis and so on.
l Abundant Contacts 7 digital input contacts and 2 pairs free output contacts are available. Input contacts are compatible with free contacts and 0~250V potential contacts, with adaptive identification.
l Uniform Structure with Mainframe Integrated The stand-alone device is portable with dimension 400x370x140mm3 and weight 13kg, which is convenient for flow test. Power supply for the device is AC 220V. Operation is accessible right after device starts.

The device can not only test the protection of all kinds of relays (such as current, voltage, normal inverse, power direction, impedance, differential, low-cycle, synchronization, frequency, direct current, auxiliary and time) and microcomputer protection units, but can also simulate temporary, permanent and conversion faults from single-phase to three-phase for group test. Operation is accessible right after switching on, which is convenient and speedy.
