The RD05 series is a universal frequency converter for controlling pumps and fans and for general automation applications. The drive is designed for operation in 1×220 V and 3×380 V supply mains and power from 0.75 to 22 kW. The drive has a built-in RS-485 network interface. Having “booklet” design, this drive series allows for wall-to-wall mounting without compromising performance. Separation of the cooling system prevents air flow through the electronic components, which increases the service life of the frequency converter. The efficient cooling system allows operation at ambient temperatures up to +50 °C. The RD05 frequency converters can handle motor cable lengths up to 150 m without reducing nominal performance. The RD05 Basic Drive reduces user costs and commissioning time due to built-in elements such as EMC filter, brake interrupter unit, and user-friendly operator panel with potentiometer.
