The SecureStart™ electronics module is designed for use with single phase Copeland™ compressors in a variety of applications. It is best suited for applications where in-rush current is regulated or where current variations are common. This device can be used with Copeland Scroll™ single-stage, Copeland Scroll UltraTech™ two-stage or Copeland Scroll Digital™ compressors.

Dramatically Reduced Light Flicker

Upon start-up, electric motors consume large amounts of current as they accelerate and build up a magnetic field. Starting currents may reach five to eight times the levels of nominal operating currents. By limiting starting current by up to 75%, the SecureStart module eliminates nuisances such as light flicker caused by current variations (see graph below). Over time SecureStart self-adjusts to motor starting current thereby eliminating any manual calibration. The SecureStart module is designed for motors with a maximum operating current of 32 amps.

Compressor Protection

SecureStart provides additional benefits by continuously monitoring motor current and voltage. When conditions such as low supply voltage or locked rotor exist, this module will switch off the motor. A delay function provides additional protection in the event of an emergency shutdown.

Additional SecureStart Benefits:

  • Easy to install
  • Self contained, light weight, compact design
  • Flame retardant ABS plastic enclosure
  • UL, CE and RoHS compliant
  • Proven performance in the field


The SecureStart module is ideal for applications where in-rush current is regulated or where current variations are common and can be applied with the Copeland compressors below:
