Overview

SureStart Series is the original single-phase soft starter specifically targeted to reduce light flicker caused by the startup of fixed speed permanent split-capacitor motors (PSC). These motors are often of the scroll compressor types which are commonly used in air-conditioning and heat pump applications. The SureStart has the latest innovations from Hyper Engineering that includes several new features:

  • 60-70% reduction in direct on-line (DOL) orin-rush current.
  • Sophisticated under voltage protection.
  • Motor reversal protection.
  • Self-adjusting up to nominal 7 hp for optimal start performance.
  • 50/60 Hz compatible.
  • ETL, CE, EMC, and RoHs compliant.
  • Tolerant to “dirty power” conditions.
  • Versions available for retrofit installations or OEM production use.
  • Fault LED.
  • Internal Current Limiting.

Note: 

  1. This product requires installation by a certified installer. At checkout, you can request matching to an installer in your area. 
  2. Since conditions of use are outside Enphase or Hyper Engineering's control, we cannot assume any liability for results obtained or damages occurred due to improper application.
