Overview

SEC711 is a professional bipolar electronic expansion valve controller developed for modern commercial HVAC, reversible heat pumps and industrial refrigeration systems. As the intelligent control core of HVAC refrigeration throttling loop, it adopts advanced PID control algorithm, specially designed to drive VPF series bidirectional stepper electronic expansion valves. It collects real-time signals from pressure and temperature sensors to automatically adjust valve opening, stabilize evaporator superheat, optimize system operation efficiency and reduce unit energy consumption. It supports 8 working modes including superheat control, temperature control and pressure regulation, equipped with RS485 Modbus RTU communication interface, supports DIN rail installation, and is widely compatible with mainstream pressure sensors and temperature sensors for refrigeration systems.
