Product Description:
The 178B0623 Frequency Converter is designed for industrial motor control with reliable performance. The model supports a wide frequency range and high torque during start up. It ensures system stability under various operational loads.
This 178B0623 frequency converter from Danfoss operates at 3 × 380 – 460 V input. It supports 50 - 60Hz supply and 0 – 1000Hz output frequency. The unit delivers a current of 7A input with 7.2A output max and 6.3 A continuous. The apparent output power of the converter is 5.2 kVA. It offers a starting torque up to 160 % for 0.5 seconds while the acceleration torque is rated at 100 % and overload torque reaches 110%. The converter operates within ambient temperatures of up to 45 °C (113 °F). The chassis protection rating of the model is IP20. This ensures basic protection against solid objects. The frequency resolution is precise at ± 0.003 Hz that allows accurate speed control. The system response time is 3 milliseconds which supports rapid control feedback. The speed regulation in open loop mode offers a 1:100 control range of synchronous speed. For speeds under 1500 rpm, accuracy is ± 7.5rpm and for speeds over 1500 rpm, the error is limited to 0.5 % of actual speed.
The 178B0623 frequency converter safety features include monitoring of intermediate circuit voltage which cuts off the converter if voltage limits are exceeded. It also shuts down automatically if a motor phase is missing. In case of a mains fault, it enables a controlled deceleration to protect the motor and system. The frequency converter ensures operational reliability through these built in protections. These safeguards help maintain consistent performance and avoid damage under fault conditions.
