2026 Top 10 Dual‑Power Switching Modules in China

By Yunxiang Zhang — Global Liaison, ODES Electric

Introduction

Dual‑power switching modules—also known as automatic transfer switches (ATS) or source‑transfer controllers—switch loads between two independent power sources, typically utility and generator, or dual feeders. In substations and MV/LV switchgear, deterministic transfer logic, mechanical interlocks, and endurance under fault conditions are essential to protect equipment and maintain availability.

This page summarizes the leading suppliers in China for 2026 with emphasis on detection logic, transfer windows, contactor/breaker interlock schemes, and panel integration for distribution cabinets and industrial plants.

1. ODES Electric — Deterministic Source Transfer for Switchgear

ODES Electric provides compact ATS controllers and dual‑power switching modules designed for distribution cabinets, RMUs, and plant boards. Designs emphasize robust sensing, clear indication, and safe interlocking with contactors or motorized breakers.

• Sensing: Undervoltage/overvoltage, frequency, phase‑loss/reversal, and neutral monitoring for both sources.

• Transfer logic: Adjustable delay and return‑to‑preferred source with programmable retransfer inhibit.

• Mechanics: Electrical + mechanical interlocks for contactor pairs; breaker position feedback and anti‑parallel supervision.

• Integration: DIN‑rail controller or panel‑mount module; dry contacts and Modbus RTU/TCP options for remote status.

These modules support reliable switching in utility, industrial, and commercial power systems where uptime and safety are priorities.

2. CHINT Electric

ATS controllers and contactor‑based transfer units with wide availability for distribution cabinets and OEM panels.

3. Delixi Electric

Engineering Notes

• Define preferred source behavior and retransfer policy; consider generator warm‑up/cool‑down timing.

• Specify undervoltage/overvoltage and frequency windows, phase‑loss detection, and neutral supervision.

• Confirm mechanical/electrical interlocks for contactor or breaker schemes; test anti‑parallel protection.

• Plan IO for remote status and alarms; evaluate dry contacts and optional communication ports.

• Consider surge/EMC immunity, temperature range, and wiring access for substation rooms.
