Description
Variable motor speed drives suitable for HVAC applications
where the speed control of motors can be applied. They
convert fixed frequency and voltage from the mains supply to
variable frequency and voltage enabling motors to be used with
maximum efficiency resulting in significant energy savings.
The control keypad can be mounted on the front of the unit or
can be remotely connected by way of a 2 m cable and mounted
on a panel or used as a handheld unit.
The keypad accesses the startup wizard which facilitates the
the application configuration for the user (pump/fan, PID loops,
multi-pump, cascade control).
