CDRA-K3 Series Built-in Bypass Soft Starter is an advanced and innovative motor control device that integrates power electronics, microprocessor technology, and modern control theory. This product effectively reduces the startup current during the startup of asynchronous motors and is widely applicable to heavy-load equipment such as fans, water pumps, conveyors, and compressors. It serves as an ideal replacement for traditional step-down starting methods like star/delta switching and self-coupling step-down startup.
As a multifunctional motor control device, the product offers soft start, soft stop, and multiple protection features, ensuring an impact-free and smooth motor startup. Equipped with a built-in bypass contactor and control power supply, the product simplifies installation, allowing users to connect the input terminal of the soft starter to a circuit breaker and then connect the motor directly to the soft starter for immediate use.
Technical Characteristics
AC 3PH 200V-240V : 0.4-93kW AC 3PH 340V-420V : 0.75-630kW
Excellent Performance - Due to a new vector control algorithm, the inverter features high starting torque, quick torque response and high control precision simultaneously increasing the efficiency of the motor
Strong Function and Low Cost - The large number of internal function modules such as timer, virtual time-delay relay and math operation modules are as a whole equivalent to an additional small PLC thereby reducing cost significantly
Easy Operation - A special-purpose function is embedded, and the conversion between the special-purpose function and the common function is available through one function code, for the convenience of type selection and flexibility in use.
Flexible Type Selection - The 15kW or below types have standard internal brake units, the 18.5-30kW types can have optional internal brake units, and the 37kW above types shall be connected with external brake units. The 1kW, 15 kW, 200 kW or above types have standard DC inductors, and 18.5-55kW types can have optional DC inductors.
