New HVAC VSD launched

May 2006 Motion Control & Drives

LS Industrial Systems is offering its iP5A series of HVAC variable speed drives. The range is specifically designed to cater for building airconditioning systems and centrifugal pump installations, incorporating Metasys and other HVAC orientated protocols. A fan/pump speed reduction of 20% requires only 64% of the full speed load. Similarly, a fan speed reduction of 30% will require only 49% of the rated full speed load.

This square law characteristic makes the use of the standard VSDs uneconomical, as their output stages are designed to handle high overload currents. With the output stage typified for HVAC applications, a significant reduction in drive cost has been made possible. The new LS iP5A range includes all the sought-after protection including short-circuit proofing earth-leakage proofing (on the run), plastic coated circuit boards, etc.

Features such as multimotor control, enable the drive to control a pump station of up to five pumps, using analog level or pressure control, without the requirement of a PLC for pump switching and sequencing. Full PID control is a standard function, with either a local or a remote set-point value. As with all LS Industrial equipment, the iP5A range has been designed for a MTBF of 200 000 hours.
