CMC-HX Electronic Soft Starter for Induction Motors - China Suppliers & Factory, 380V, 7.5-995 kW
Features
The SCR close-loop control is specially designed for standard load and heavy load. User can choose current-limit start or voltage ramp start according to load conditions so as to realize absolutely smooth start without torque oscillation.
It is built-in 10 kinds of load types for users to choose. It provides a unique start control curve for each type of load to make soft start match the load, so as to achieve the best start and stop.
Voltage exponential curve start, voltage linear curve start, current exponential curve start, and current linear curve start. Programmable kick start torque and start current limit can be applied in each mode. According to the different loads, you can choose the corresponding start curve to achieve the appropriate starting effect. The device is provided with a variety of stop modes including programmable soft stop, free stop, braking, and pump stop. Unique basic algorithm makes the motor start and stop accurately and smoothly.
Standard Modbus RTU communication. Optional Ethernet/GPRS communication module makes user’s network connection control easier and improves the system's automation level and reliability.
Users can input 4-20mA or 0-20mA standard signal, and conduct upper and lower limit setting of analog to achieve the start and stop control of motor and alarm. The data (pressure, temperature, flow, etc.) can also be transmitted via a soft starter. 4-20mA or 0-20mA standard analog signal output function.
The product of below 90KW is in plastic structure made with inflaming retarding ABS material; for the product of 90KW and above, the upper cover is in plastic structure and main frame is made of aluminium-zinc plate with features of heatproof and corrosion resistance.
The panel can be moved to equipment operating surface through machine interface for remote control.

With two sets of basic parameters, it can control two motors with different power respectively.
Self-adaption of power frequency 50/60 makes user easy to use.
Up to 10 failures can be recorded, making it easy to find the cause of the malfunction.
It detects current and load parameters, having overcurrent, overload, underload, overheating, phase failure, short circuit, three-phase current imbalance, phase sequence detection, frequency error and other functions.
LCD liquid crystal display panel; support English display.
