Automatic Transfer Switch(ATS)
The ATS (Automatic Transfer Switch) series delivers versatile three-phase AC power solutions, enabling seamless switching between primary and backup sources for industrial, commercial, and critical infrastructure applications. It encompasses CB-Class and PC-Class models (e.g., YCQ9, YCQ9Ms, YCQ9B-63) with tailored current, protection, and performance specs, unified by core reliability and adaptability.
Covering 10A–800A current ratings with 2P/3P/4P configurations, the series integrates overvoltage (OV), undervoltage (UV), and phase protection. With short-circuit making capacities from 5kA to 100kA and CE compliance, it supports grid-to-grid and grid-to-generator scenarios.

FAQ
What does an automatic transfer switch do?
An ATS (automatic transfer switch) automatically switches power supply from primary to backup sources (e.g., grid to generator) during outages, ensuring uninterrupted power for industrial, commercial, or critical infrastructure.
What's the difference between ATS and STS?
ATS handles high-power AC switching (e.g., 10A–800A) for three-phase systems, ideal for heavy loads. STS (Static Transfer Switch) is for low-power DC/AC with faster切换 (milliseconds), suited for sensitive electronics.
What is the disadvantage of an automatic transfer switch?
Higher initial cost compared to manual transfer switches; requires professional installation and periodic maintenance to ensure reliability.
What is the difference between ATS and transfer switch?
"Transfer switch" is a general term; ATS is a subset with automatic switching. Manual transfer switches require human operation, while ATS triggers automatically during power failures.
What types of ATS are available?
Our series includes CB-Class (circuit breaker-based) and PC-Class (contactor-based) models, with 2P/3P/4P configurations and 10A–800A current ratings for diverse industrial/commercial needs.
What certifications does your ATS have?
All ATS products comply with international safety standards and mainstream certifications for global markets.
Do you support OEM/ODM services?
Yes, we offer OEM/ODM customization for ATS, including branding, specifications, and design tailored to client requirements.
What is the lead time for ATS orders?
Lead time varies by region and order volume; contact our team for a detailed quote based on your location.
