Compact modular Powerdrive is robust and efficient

Leroy Somer's design engineers have succeeded in making the new Powerdrive variable-speed drives reliable and easy to install, commission and maintain. One way they have achieved this is by keeping components and wiring to a minimum.

Compact modular Powerdrive is robust and efficient

Covering the range 45-675KW, Powerdrive is modular with air or liquid cooling and offers open- or closed-loop vector or simple V/F control. The individual inverter, rectifier, cooling and electronic modules make for easy accessibility and the front-mounted HMI panel and optional remote keyboard make reading and writing the main parameters extremely simple.

Included on the Enhanced Capital Allowance list, Powerdrive can be ordered already configured for most major applications, allowing commissioning to be achieved with only eight parameters. There is automatic auto-tuning at the first start-up and all the parameters can be saved to the patented Xpresskey with one click of a button.

Multilingual, PC-based commissioning software provides a motor database, user help and a set-up wizard. The drive also tests itself at low voltage on initial switch-on to avoid irreparable damage in the event of shorts or earths on motor phases, for example. The drives are also much less susceptible to power disturbances thanks to new technology developed in collaboration with EDF.

Powerdrive's enclosures are sealed to IP21 or IP54 and there are numerous options such as filters, encoders, units for most Fieldbus protocols, dynamic breaking and emergency-stop features.
