Smaller inverter drives January 1st 2006 Moeller Electric has added two new models to its DF5 and DV5 inverter ranges. The DF51 is designed specifically to provide energy efficient speed control for fans, pumps and similar variable torque loads, while the DV51 combines high starting torque with accurate sensorless speed control for constant torque applications such as mechanical handling and hoists. Available with ratings up to 7.5kW, both drives have integral Modbus communication facilities, making them easy to integrate with factory or building automation systems.
Requiring 40% less space in the control panel than its predecessor, the DF51 V/f drive has built-in PID functionality.
In the DV51, the sensorless vector drives have removable keypads, meaning a single keypad can be used to set up many drives - and protecting against tampering.
