Millisecond Switching Guarantee: Solenoid Type ATS Empowers Uninterrupted Power Supply in Critical Scenarios

In modern society, the continuity of power supply directly determines the normal operation of critical fields. Scenarios like hospitals and data centers have extremely high requirements for power stability—even a millisecond-level interruption may cause irreversible losses. As a core device for switching between main and backup power supplies, the Automatic Transfer Switch (ATS) is a key line of defense for uninterrupted power supply. Among them, the Solenoid Type ATS has become the preferred solution for critical scenarios due to its millisecond switching capability, providing solid support for high-reliability power supply needs.

1. Introduction: Core Demand for Uninterrupted Power Supply in Critical Scenarios

For critical scenarios such as hospitals and data centers, the continuity of power supply is crucial. Power outages may threaten patients’ lives in hospitals and cause data loss or business paralysis in data centers. According to Frost & Sullivan’s 2018 Business and Industrial Power Reliability Report, the average loss caused by power outages in critical scenarios exceeds $100,000 per hour. The Solenoid Type ATS addresses this issue by compressing power interruption time to a negligible range, effectively avoiding related risks.

2. Technical Core: Realization Logic of Millisecond Switching

The Solenoid Type ATS is mainly composed of an electromagnetic drive module, a switching actuator, and a detection control unit. Unlike traditional mechanical ATS that relies on motor and gear drive, it uses electromagnetic induction to drive the switching mechanism, fundamentally improving switching speed and accuracy. Its switching speed can be as low as 80-150ms, meeting the IEC 60947-6-1 standard (≤200ms for critical scenarios), with a rated current ranging from 63A to 6300A for both residential and industrial applications. Some high-end models are equipped with an RS-485 interface for remote monitoring.

Hospitals require switching time

4. Stability Guarantee: Design to Avoid Power Fluctuations

Power fluctuations during switching are caused by mechanism delay, unreasonable circuit design, and inaccurate detection. The Solenoid Type ATS solves this through hardware (high-quality electromagnetic components, voltage buffer modules) and software (precision detection algorithms, fault self-diagnosis) optimization, complying with IEC 60947-6-1 and IEC 60364-5-56 standards.

5. Advantage Comparison with Traditional ATS

Compared with traditional mechanical ATS (switching speed >500ms), the Solenoid Type ATS achieves 80ms switching. It consumes power only during switching (almost zero standby energy consumption), has less wear, lower maintenance costs (1/3 of traditional ATS), and a longer service life (10-15 years vs. 5-8 years).

6. Practical Cases

A Grade A hospital replaced traditional ATS with Solenoid Type ATS, reducing switching speed to 120ms and achieving zero interruption for 1 year. A Tianjin cloud computing center used it to handle 2 power failures with switching time <100ms, maintaining PUE ≤1.3 and reducing operational costs.
