The VSD2H range of variable motor speed drives are especially designed for use in the HVAC environment,enabling fans and motors to regulate delivery of air and water in variable flow applications.
A control pad is supplied mounted on the front of the unit and can be detached to be used as a panel mounted or a handheld unit.
The control pad is multilingual with menu driven selection options, scrolling text messages and setup wizards for extremely fast start of basic pump and fan applications.
Compact size, slim, space-saving, bookshelf design
An optional Trend Network Interface Card interface can be fitted into the VSD2H drive to allow the system to be monitored from Trend supervisors and controlled from trend IQ controllers.
