Even when they’re operating outdoors in extreme weather conditions, ac variable speed drives in the latest VACON® 100 X range need no additional protection of any kind, making them a cost-effective and convenient choice for use in demanding environments where ordinary drives would need to be mounted within a protective enclosure.

With a power range up to 37 kW, which is unmatched by competitive products, VACON 100 X drives feature a rugged die-cast metal enclosure with an IP66 ingress protection rating and have an exceptionally wide operating temperature range of -40 ºC to +60 ºC, allowing them to perform reliably and consistently in even the toughest of operating conditions.

The drives can be mounted in any orientation and are also resistant to vibration up 3g. They can, therefore, optionally be mounted directly on the motor they are controlling and, in appropriate applications, this can result in valuable space savings as well as reducing the amount of cabling required.

Suitable for use with standard induction motors and with the latest high-efficiency permanent magnet motors, VACON 100 X drives fully support decentralised control system architectures and, as standard, they have integrated RS485 Modbus and Ethernet communication ports. The also have built-in EMC filters for EN61800-3 category C2 applications, and can optionally be supplied with filters for C1 applications.

Other key features of the robust drives in the VACON 100 X range include a safe-torque-off (STO) mode that conforms with the requirements for SIL3, an integrated brake chopper and a PTC input that can be used to provide enhanced motor overload protection. In addition, they use the latest film capacitor technology to ensure long working life and to minimise environmental impact.
