Variable speed drives G120P – a product range for all needs

SED Variable SPeed drives products

The G120P family includes variable speed drives for applications ranging from the industrial to the residential sector, ensuring energy-efficient and intelligent speed control of pumps and fans in HVAC systems. The G120P is available in different frame sizes and consists of control unit, power module and operator panel or blanking cover. You can choose between EMC filter type A and B. The drives conform to communication standards USS, Modbus RTU and BACnet MS/TP. CANopen and PROFIBUS are available as options.

Thanks to the drive’s modular concept, you only buy what you really need – an intelligent operator panel, the basic version or simply a blanking cover. Only one operator panel is required to parameterize several variable speed drives. If a component is worn and must be replaced, there is no need to purchase a complete drive. And if the power module is changed, reparameterization is not required. In short: In short, modular design means increased service flexibility, reduced costs and environmental friendliness.
