Description

Fan speed controller 0-10V/4-20mA ERV 5A

Works at 5A

The ERV series are speed regulators by phase control for single phase fans. They have a control input that permits to control the regulator by means of an external signal.
The regulator allows to be controlled by a 0-10VDC input or a 4-20mA input, that can be selected through the selector SW2.
