DC speed controller ZEC 2

EC

ZEC 2 - 5-STEP VOLTAGE CONTROLLER 0-10VDC Controller is designed to control the speed of ventilators equipped with electronically commutated motors (EC) or other devices controlled by 0-10Vdc signal. Required power supply is 10-12V /1mA, which is available on most of EC drivers. The output is 5-step 0-10V signal, which is controlled by 6-position switch. “0” position turns off control output. “Offset” function allows to change the level of voltage down approximately 2,5V +-20% for fifth step, decreasing for lower steps. LED diode signalizes operation of controller.
