30 Amp @ 110-230 Volts
APPLICATION
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 immediately takes
over 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 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.
The LED in the unit indicates when the unit is
ENERGY SAVING. As energy consumption is
reduced the ENERGY SAVING LED flashes at a
slower rate.
The HFE remains in circuit until the supply is discon-
nected. The HFE automatically resets and is ready for
the next start.
