Hyper Engineering Soft Starters for Commercial HVAC Air Conditioners Three Phase

Three Phase Soft Starters

The Sure-Start 3 phase soft starter connects between the contactor and the motor. It reduces the starting current and offers a controlled start to limit the damaging start-up and noise in a three phase motor compressor. They are also designed to offer reverse phase protection for motors.

The Sure-Start 3 phase soft starter is also designed to learn the motor characteristics of the load. After a few starts, it will have automatically adjusted itself to the load and the electrical supply impedance at the site. Our soft starter is designed to function as an auto-start device. Our range of models do not require any auxiliary control input. This makes them much easier to install and are readily compatible with different installations. Sure-Start soft starters are ETL, CE and RoHS compliant.
