Eriks UK has announced the launch of Fenner's Quickdrive (QD) range of inverters and electric motors.

The range is available in a number of designs, including IP55 variants of the QD:Easy and QD:Constant Torque Plus, which are suited to harsh environments.

The company said the QD range is easy to install and commission and has many beneficial features and functionality.

The range caters for variable torque applications and those needing high-performance open-loop requirements and simple speed control such as heating, ventilating and air conditioning (HVAC).

The Fenner QD:E range is a basic, simple-to-use drive available in ratings from 0.37kW to 11kW.

The range is competitively priced, with factory pre-set settings that are suitable for most applications.

The 14 basic parameters can easily be adjusted to suit more demanding requirements.

The QD:E units have an overload capacity of 150 per cent for 60s, and are supplied with an integral RFI filter.

Repeat programming can easily be carried out with the aid of the new Fenner Q-stick, a memory stick that plugs into the front of the drive to allow the specific parameter settings to be uploaded quickly and efficiently.

Suited to providing energy savings in HVAC applications is the QD-VT (variable torque) range.

This range is specifically designed for use with fans and pumps and is available with ratings from 1.5kW up to 160kW.

Integral RFI filters are fitted as standard and each drive is capable of a number of real-time energy optimising functions, together with integrated PID (Proportional Integral Derivative controller) functionality.

The QD:CT (Constant Torque) Plus range offers open-loop vector control for motors with ratings from 0.37 kW to 160 kW.

These drives are capable of delivering 200 per cent torque right down to 0 Hz, allowing them to be used in many applications where closed-loop control would have previously been essential.

Setting up QD:CT Plus drives is simple - all that is needed is the data found on the motor plate.

The drive will then continuously (and automatically) track the motor characteristics and, using the vector control algorithms, adjust for optimal performance ensuring maximum torque at low speeds.

Completing the range are the enclosed QD:E IP55 and QD:CT PLUS IP55 units that offer a fully weatherproof drive suited for even the harshest of industrial environments.

The front facia comes complete with speed control knob, forward/reverse or, lockable isolator and full programming keypad and display.

Fenner QD drives from Eriks are Modbus compatible and can be converted to allow easy integration with Fieldbus and Ethernet connections via the RS485 port.

All QD drives can operate in ambient temperatures from 0C to 50C for IP20 units and 0C to 40C for IP55 units.
