Variable Speed Drive
The variable speed drive is an auxillary feature avail-
able on all EMAX compressors. A variable speed drive
or VSD will save energy consumption and wear on the
electric motor. The VSD regulates amp draw during
start-up and motor speed during operation according
to air demand.
All EMAX compressors are equipped with a VSD com-
pliant motor, ventilated electrical box and adequate
space in compressor cabinet for easy installation.
The electronic controller (PLC) for the compressor
unit, has a 4-20 milliamp control signal built-in to
control VSD speed reference. The PLC can provide
start/stop command and display any fault codes for
the VSD device.
To convert to Varible speed drive,
contact EMAX customer service for
more information. 1-866-294-4153.
Be sure to install VSD in a clean, dust-free
environment.
