PRS3000 / PRS3000B series Soft Starter is original structure, small volume, reliable performance, convenience for installation, easy operation and use.

Three reverse-parallel connection SCR modules are adopted as power element. The soft starter can pick up

synchronization signal from input voltage sampling, and realize feedback fuzzy control by output current

sampling, trace the phase automatically and control phase displacement angle. Voltage can thus be increased step by step, and startup current will be under control. After startup, the bypass contactor will short-circuit the SCR. The motor will finally be driven into the electricity network for operation, applied for fan, water pump, ball mill, compressor, crusher, conveying machines and so on.


1.Adopt 16-digit SCM, full digital automatic control;

2.Main circuit connection is 3-inlet & 6-outlet, realizing online protection;

3.Thyristor module made by japan Sanrex Corporation,

and CPU with chip supplied by Philips Corporation;

4.The starting torque current, voltage and time can be

set flexibly according to different loads;

5.Soft stop character;

6.Protections against over current, over load, power

failure and so on;

7.Convenient external control interfaces has multi-

functions: digital time-delay starting control, soft-stop control input, starting delay relay output, fault relay output, etc;

8.Can identify the phase sequence;

9.The time of soft stop is adjustable;

10.With standard RS232/RS485 interface;

11.PR3000B:Built-in bypass
