Product Description:

The Danfoss 5000 series frequency drive 175Z0137 has been put together in compliance with the product code VLT5004PT5C20STR3DLF00A00C0. It is intended to be used in industrial environments with input of 380 to 500 V AC at 50/60 Hz frequency and it can provide an output of 0 to 100% of the supply voltage that is adjustable.

The 175Z0137 drive features high overload with an initial torque of 160% up to 60 sec and it supports a maximum output current of 9 A, while its typical shaft output 2200 W. The drive achieves 96% efficiency at full load with minimal energy loss during operation and its maximum power loss at full load is approximately 110 W. It includes an advanced motor thermal protection feature, which ensures the motor is protected against overload conditions and its maximum short-circuit rating is 100000 A, while it offers full protection against earth faults and motor terminal short-circuits as well. The 175Z0137 drive features an overvoltage and undervoltage protection system that ensures the system remains safe under fluctuating electrical conditions. It comes with multiple input options that includes eight programmable digital inputs with a voltage range of up to 24 V DC and 1 programmable analog current input with a range of 0 or 4 to ±0.0020 A.

The 175Z0137 drive is presented with a maximum frequency of up to 65 kHz for pulse/encoder inputs for precise speed control and it supports communication via RS485. It is housed in a durable enclosure with an IP20 or IP54 rating and it can handle mechanical shock as well as vibration levels as per IEC 68-2-34/35/36 standards. The drive can achieve up to 1000 Hz of control frequency range that makes it adaptable to a variety of motor control needs.
