HD2 – AC Variable Speed Inverter Drives


The HD2 range of AC Drives are high performance, open and closed loop vector control inverters specifically designed for controlling asynchronous AC induction motors and permanent magnet synchronous motors. Utilising the most advanced vector control technology, the HD2 range offers unparalleled reliability, environmental adaptability, high precision and stable performance.

What is an AC Variable Speed Inverter Drive?

Whether you call it an AC Variable Speed Inverter Drive, a Variable Frequency Drive, a Variable Speed Drive, Micro Drive, or just an AC Inverter, it is a type of adjustable speed drive used in electro-mechanical drive systems to control AC motor speed and torque by varying motor input frequency and voltage. AC Variable Speed Inverter Drives are used in applications ranging from small appliances to large industrial compressors. About 25% of the world's electrical energy is consumed by electric motors in industrial applications, which can be considerably more efficient when used in conjunction with an AC Variable Speed Inverter Drive, saving both energy and money.

Why the HD2?

When selecting an AC drive, two important factors are performance and price. Performance because you need to ensure your inverter can cope with the most arduous applications, and price because AC drives are often about saving energy, and a short pay-back time on capital expenditure is key. The HD1 delivers on both these counts.

HD2 Features

The HD2 range with its high performance and extensive range of features and options lends itself perfectly for both demanding load applications and building management systems where communication and control are a must. With a plethora of extension cards for additional IO or communication options as well as numerous encoder cards providing closed loop control, the HD2 has it covered. The full LCD keypad with 16 lines of readable text makes the drive simple and intuitive to program.
