HFE Energy Saving soft starters are designed to control single phase AC motors. Operation is fully automatic, a low starting voltage is applied to the motor as soon as the supply is switched on. The internal automatic ramp control is immediately activated and raises the voltage progressively, causing the motor to accelerate smoothly.
At the end of the ramp period, the motor is operated in Energy Saving (iERS) mode and the HFE continuously regulates the voltage to match mechanical load. Energy consumption at light loads is reduced, motor winding and case temperatures are lowered, motor life is extended, noise levels are reduced and power factor is improved.
Two LED’s on the front of the unit indicate when the POWER supply is connected and when the unit is in iERS mode. As energy consumption is reduced the iERS LED flashes at a slower rate.
The HFE remains in circuit until the supply is disconnected. The HFE automatically resets and is ready for the next start.
