Product Description

Motor soft starter
220-500V
12-420A
Effective in improving motor start, stop characteristics
From power and mechanical shock, extended equipment life

6 Thyristor Three-phase full wave control, quality start, stop characteristics. (Generally two-phase control can not compare)
With sufficient cooling capacity, long life, free installation of By Pass electromagnetic contactor.
Micro-computer digital control, high precision, multi-functional, easy to control adjustment, and with less phase and temperature protection.
Electronic, no contacts, no noise, semi-permanent life.
Small size, easy wiring, only to receive the three motor wires.
Replace the Y-△ electromagnetic switch, auto transformers, reactors and other traditional control, and more value.

At startup, to limit the supply voltage drop rate, or reduce the surge current,
Limit starting torque to protect the mechanical load driven
To be smooth acceleration or deceleration in order to prevent the object being driven fall, when dumping
High inertia loads, the slow start may be required to protect the motor and precision equipment
To be smooth all the other start, stop function, but not for speed control of machinery and equipment
For example: pumps, windmills, conveyors, cranes, shredders, centrifuges, ice machine, air compressor ... etc.
When used for pumps, water pressure to prevent an instant impact and stops the water hammer effect

To prevent the start due to phase
Less if the main power before starting phase, the Err. Yellow long light, and to prohibit start. (Main power K1, K2, K3, and then other components can not, or will be affected due to phase detection)
SCR overheating protection
When the heat sink temperature is higher than 80 ± 3 ℃, then the automatic buffer stop or prohibit the start, and Err. Yellow light flashes.
Cooling fan to protect
Fan cooled models, with fan operation control:
A. When the grants power transmission, the fan running 10 seconds prior to stop (easy to confirm if the fan works)
B. When the cooling temperature is higher than 55 ℃, the cooling fans start to turn, lower than 50 ℃, the cooling fan to stop, effectively extending fan life.
