We integrate scientific research, development, production, sale and service in one company. Our custom soft starters products are characterized by their superior dustproof, splash-proof, anticorrosion, fire-resistant, thermo-stability and aging-resistant properties. Having received ISO9001 certification for our manufacturing and sales systems, we have also been issued European 'CE' and Chinese 'CCC' safety authorizations for our products. All of our OEM soft starter products are strictly according to IEC/GS/EMC/LICE/UL/CSA standard and guaranteed by People's insurance Corporation of China (PICC).

HPS2DN15...840 series is a sort of current-controlled intellectual soft starter newly designed on the basis of HPS2S, HP2D/DH and adopting the most advanced digital
processor to regulate voltage. Its unique intellectual electronic circuit provides perfect controlling and protective functions: linearity acceleration start,pump start, pump stop control, preset low voltage operation, preset both of parameters for soft start and soft stop and switch each other freely, monitor load status and automatically change to the light -load and energy-saving pattern,protective function of testing motor insulation, phase loss, short circuit, protection against over-load, etc. With RS 485 and Profibus protocol, which realizes full micro-controller and monitoring.

The HPS2S 18/30...HPS2S300/5 15 is a type of flexible and multifunctional softstarter which could be adopted by most situations and substitute Y/ starts All the control connection and parameter adjustment are completed on the face due to converiences in installation and modification. The board forward presents an obvious working status and error analysis. The Sotstarter could be easilly modified by the customers after installation such as accessional function of current-restricting and alternative of inside connection or outside Connection. The machine is able to successionally operate on line without bypass. A control relay of machine was set solely for faults and bypass. It is accurate and simple to set the parameters with three knob potentiometers and dial switch.
