Finally, a solution to annoying LIGHT FLICKER!  

 

The new 1P100-ST is the only available, specially engineered, SCR Soft Start that will meet mandatory Rule 2 compliance for Maui County or other Municipalities that require limiting Inrush below 100 AMPS. This is also the only Soft Start that is approved by Rheem Mfg. for use on their new or existing           1.5 – 5 ton Air Conditioners, without violating the WARRANTY.

 

The 1P100-ST uses the latest Digital Signal Processor (DSP) and is easily connected in series between the contactor and the compressor, making the installation fast and easy. The Soft Start feature is optimized through advanced proprietary software used to program the Texas Instruments solid state DSP. This solid state, NASA inspired technology incorporates silicon rectifier switches, which will deliver years of reliable and maintenance free service.

 

Rheem Mfg. subjected our soft start to extensive testing followed by Copeland’s inspection of their AC test compressor, which revealed no unusual wear or damage.  As a result, Rheem Mfg. has approved the 1P100-ST soft start for their 1.5 – 5 ton, 1 phase air conditioners/heat pumps where the goal is to reduce inrush current.
