Digital potentiometer for V/F Speed Controllers EM-3790.1

EMKO EPM-3790.1 is a digital potentiometer designed for precise speed reference control of V/F (Variable Frequency) motor speed controllers. Featuring a 4-digit LED display, forward and reverse direction outputs, fault input monitoring, and adjustable ramp-up/ramp-down functions, it provides smooth and reliable motor speed control in industrial automation applications. The unit supports configurable display scaling from -1999 to 9999 and offers either 0/2–10 VDC voltage output or 0/4–20 mA current output for seamless integration with variable frequency drives. With IP65 front panel protection and easy front-panel parameter adjustment, the EPM-3790-N is ideal for conveyor systems, pumps, fans, and industrial motor control applications.
