Product Description:
This 178B0237 HVAC drive’s control panel consists of a display and a keypad. The drive comes with a preset protection against overload of the motor. This product features improved speed regulation. The device facilitates mounting near another drive. This unit’s RFI filter complies with EN 55011 Class A1 specifications if the screened motor cable is 150 m long. Its PID regulator allows two feedback signals to be connected. The drive comes in a user-friendly design.
This product portrays high starting torque. The device highlights the local speed of the drive on its graphical display. This unit comprises a flying start function. It supplies the motor with variable frequency plus voltage. The drive’s automatic energy optimization function is activated by default. This product regulates the pressure constantly in a water supply system. The device’s ramp time varies from 1s to 3600s. This unit’s programmable pulse inputs have a maximum frequency based on the terminals they are associated with. Its 24 VDC power supply and the analog inputs have the same potential.
The drive’s minimum ambient temperature at reduced performance is -10 °C. This product executes a controlled deceleration when a mains fault is triggered. The device’s installation should ensure its proper cooling through the circulation of air. The unit requires adequate clearance at its top and bottom to release the cooling air. It supports flange-by-flange mounting. The HVAC drive’s installation is possible only on a flat surface. This product’s motor cables and control cables should be separated by at least 20 cm. The device can’t be used with Type A ELCB relays. This unit’s RFI switch should not be operated when the drive is actively connected to the mains. It uses braided screened cables as its control cables.
