Design and Manufacturing of Industrial Electric Machinery, Motor Soft-Start

■With RS485 ModBus communication function, it could display the working current, output percent, internal temperature of the machine and twelve faults.
■Settings of multiple functions and protection parameters:
>Current limit, overload function setting, detection of overload current ratio, setting of time parameters.
■Various fault indicators and protections:
> Input power phase failure and out of phase indications, Overload protection、Overheating protection, and SCR gateway short circuit protection.
3-phase power regulator with load disconnection detection that allows setup of sensitivity and effective time, with the sensitivity that can detect one broken set of the 5 sets.
1-phase power regulator with load disconnection detection.
■ Start/stop delay time setting.
■ Provide signal input control of 4-20 mA, 0-5V, 1-5V, 0-10V, 2-10V.
■ Built-in intelligent overheat protection and indicator, equipped with intelligent cooling fan.
■ Fault output contact provided for emergency control of system in case of faults detected.
■Built-in high-speed fuse especially for semi-conductor, to provide protection from short circuit.
■ Special use to Silicon carbon rod、molybdenum(IV) oxide load.
