Name: VSD2001 HVAC Electronic Expansion Valve Drive Module
SKU: VSD2001
Availability: InStock

Overview

VSD2001 is a dual-channel independent electronic expansion valve driver developed for commercial HVAC, reversible heat pumps and industrial refrigeration systems. It receives analog control signals (0~10VDC or 4~20mA) from main controller to adjust valve opening continuously. It supports independent selection of unipolar and bipolar drive modes, fully compatible with Sanhua VPF, DPF, LPF series stepper electronic expansion valves. Equipped with RS485 Modbus RTU communication interface, supports up to 32 units cascading. It adopts DIN slide rail installation, with forced open/forced close function for on-site debugging, widely used in systems requiring two independent refrigerant flow control loops.
