Frequency converter OWEN PChV203-5K5-V

Frequency converter OWEN PChV203-5K5-V

The universal low and medium power vector frequency converter OWEN PChV2 can be used in automated drive systems with a power of not more than 22 kW, including a variety of HVAC systems, low and medium power machines, conveyor lines, spatial positioning systems, etc.
For programming and operational control of frequency converter1 serves as an operator panel LPO1 or LPO2 (supplied by separate order) . There is a potentiometer on the front of the LPO1 panel.
The factory default settings allow the user to test the operation of the drive in manual and automatic modes at minimal cost after entering the main parameters into the LPO.
