Overview

VSD1002 is a single-channel bipolar electronic expansion valve driver developed for commercial HVAC, reversible heat pumps and industrial refrigeration systems. It receives analog control signal (0~10VDC or 4~20mA) from main controller to continuously adjust valve opening. Optimized for Sanhua VPF series two-phase four-wire bidirectional electronic expansion valves, supporting parameter configuration via DIP switch to match different valve full steps. Built-in RS485 Modbus RTU communication, up to 32 units cascading. Equipped with force open & force close terminals for on-site commissioning. Adopts DIN35 rail mounting, widely used in single-loop refrigeration & heat pump equipment.
