Compact and efficient variable frequency drives

Controls and automation specialist, Carlo Gavazzi has launched the RVBS variable frequency drive for speed control applications such as pumps, fans, conveyors, compressors and HVAC systems of up to 0.75kW.

The open board design is available in 0.55kW (2.7 Arms) and 0.75kW (5 Arms) versions, providing a compact solution that especially suits electrical panels where a space-optimised design is essential. Minimal set-up and push-in connectors make for a more simplified, faster and more reliable installation time.

The fanless design increases reliability in harsh environments and is equipped with optimised features to control the speed of the 3-phase compressors with an induction motor via its two digital inputs and one analogue input; the RVBS offers a flexible configuration to adapt to varied application needs.
The RVBS can be configured via the configuration software, an optional remote keypad or a PLC, providing increased operational flexibility.

Utilising the built-in Modbus RTU communication port facilitates integration with an automation system and/or PLC, allowing realtime status monitoring and data exchange of motor variables.
