Five-step voltage controller Power supply: Potentiometer: Controller 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 10-12VDC/10mA, which is available on most of EC drivers. The output is 5-step 0-10VDC 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. Protection grade: IP54. Manufactured in compliance with: EN61000-6-2, EN61000-6-3. WIRING DIAGRAM OFFSET ul. Postępowa 25/27, 93-347 Łódź, Poland tel.
