Product Description:

175Z0372 is a Danfoss VLT 5000 series frequency converter. This compact converter is available in an IP20 housing that mounts vertically. A control panel at the front – with display and keypad – allows easy and intuitive monitoring and configuration. An ID sticker is attached to the unit and lists information needed for identification, including type code, serial number, and input and output specifications. Danfoss recommends waiting for 15 minutes after AC power disconnection before performing any repair activity. ESD precautions are also recommended for preventing component damage. Input voltage for the 175Z0372 converter is 380 to 500 Volts. The input current is 3.8 Amps at 380 Volts and 3.4 Amps at 500 Volts. The converter rectifies AC input, and then inverts the resulting DC to obtain controlled AC output for motor speed control.

Output voltage range for the converter is 0 to Vin. Output frequency range for the converter is 0 to 1000 Hertz. Typical output of the 175Z0372 converter to the motor shaft is 1.5 kilowatts (2 Horsepower). The recommended motor cable size is 10 AWG and the recommended power cable size is also 10 AWG. The specified efficiency of the inverter is 0.96. Weight of this IP20 rated bookstyle unit is 7 kilograms. The peak operating power loss is 92 Watts. The main control card of the converter supports several input and outputs. These include 8 programmable digital inputs, 2 programmable analog/thermistor inputs, 4 encoder/pulse inputs, and 2 programmable analog and digital outputs. These I/Os can be used to connect a wide array of sensors, actuators, and motor encoders to the converter, increasing its functionality, improving its usability, and widening is scope of applications.
