First, the product description
1. Slow start time, stop time and the start torque can be adjusted so that the smooth start smoothly.
2. The built-in three kinds of startup modes: slope start, constant current start, constant current plus kick start automatically.
3. Use silicon controlled rectifier control: no contact, no arc, no light side wear, equivalent semi-permanent life.
4. Simple wiring: three-three means cost saving tedious manual wiring.
5. Slow start controller microprocessor type and severity of the load with automatic proofreading function and torque control.
6. The operation of the cooling fan has a temperature control, work when the heat sink temperature of 55 degrees, 45 degrees when stopped, can increase fan life 2-3 times.
7. The electronic controller includes CT detecting protection: overload, power source due to phase protection, Ma Daka died protection, over-temperature protection controller, motor low load (water) protection, ultra-sensitive sensors degrees and no heat accumulation effect, the ambient temperature is not affected.
8. The controller provides three sets of output contacts: output contact when having started operation after the completion of outputs, system abnormal output contacts.
9. The pump motor controller provides dedicated slow stop function, eliminate water hammer in order to achieve optimal function.
