Protection systems play a key role for the safe and reliable operation of today’s electricity power systems. Properly working protection devices help to maintain the safety of the system and to safeguard assets from damage. SXJB-3300 Protection Relay Tester is the essential test tool for relay protection technicians.

♦  Large LCD screen.

♦  4 phases voltage 3 phases current outputs. Each phase can output 120V, current at three paralleled can reach 120A, the fourth phase voltage Ux has multi functions, which could be set as 4 kinds 3Uo or synchronous voltage, or any one voltage value. 

♦  Good heat dissipation, long duration of large current output.

♦  Enough on-off contacts: 7 channels contact inputs and 2 pair’s idle contacts outputs. The input contact is idle and can be compatible with 0~250V potential contacts and identify automatically. Input/output contact numbers can be customized according user’s requirements.

♦  High output precision and anti-interference.

♦  High fidelity power amplifier and high-speed digital signal processor.

♦  Build-in IPC, can operate with outside laptop.

♦  Panel with keyboard.

♦  Over-heat, over-current, over-voltage and short circuit protections.

♦  Friendly English interface, easy to operate.

♦  One channel 110V and 220V independent DC source output

♦  Auto generating WORD format test report and is editable.
