IP55 Low‑Voltage Water Pump Variable‑Frequency Control Cabinet

Material: Carbon steel
Color: Gray
Place of Origin：ShanXi, China
Application：Industrial
Product Category: Control Box

This is a low‑voltage variable‑frequency control device with IP55 protection rating specially designed for water pump systems. It integrates variable‑frequency speed regulation, intelligent control and multi‑protection functions. Suitable for AC 380V/220V low‑voltage power distribution systems, it delivers precise adjustment of water pump flow and pressure via PID closed‑loop control. Compatible with single‑phase and three‑phase water pumps, it covers power ratings from 0.75 kW to 315 kW. It supports manual, automatic and remote control modes, and can connect to PLC/SCADA systems for unattended operation. The cabinet adopts a modular design to adapt to harsh industrial environments such as humidity and dust.

① IP55 high‑protection rating, suitable for harsh outdoor environments with humidity and dust for extended service life.

② Intelligent variable‑frequency control. PID algorithm realizes constant‑pressure / constant‑flow control with energy‑saving efficiency of over 30%.

③ Comprehensive safety protection. Real‑time monitoring of current, voltage, temperature and other parameters. Automatic alarm and power cut‑off upon faults to protect equipment and operating personnel.

④ Modular construction with standardized components for easy maintenance. Custom‑extended functions including liquid‑level linkage and multi‑pump switching are supported.

⑤ Remote monitoring available. Remote operation via mobile APP or PC terminal enables unattended maintenance.

Municipal constant‑pressure water supply systems, industrial circulating cooling water systems, secondary water supply for high‑rise buildings, fire sprinkler pressurization systems, water‑saving agricultural irrigation, sewage‑treatment lift pump control, central‑air‑conditioning cold‑hot water circulating systems, etc.

Q1: What pump power ratings are compatible with this control cabinet?
A: Standard models support single‑phase and three‑phase water pumps from 0.75 kW to 315 kW. Higher‑power specifications are available upon custom request.

Q2: What does IP55 protection rating mean?
A: IP55 means complete dust protection and resistance against low‑pressure water jet ingress. It fits outdoor, humid and dusty industrial conditions without extra protective housing.

Q3: Does it support remote control?
A: Equipped with standard RS485 communication interface compatible with Modbus protocol. It can connect to PLC, SCADA systems or mobile APP for remote start‑stop, parameter adjustment and status monitoring.
