AC UPS Power Cabinet in substations, thermal power plants, hydropower stations, wind farms and photovoltaic power stations

NASN POWER AC power supply cabinet is designed for power grid industrial sites. It is uninterruptible AC inverter UPS, offering non-stop backup power for critical control & communication loads. It owns comprehensive electrical protection and intelligent monitoring, suitable and widely deployed in substations,power plants, thermal power plants, hydropower stations, wind farms and photovoltaic power stations. It provides continuous backup power for critical secondary equipment including relay protection devices, power automation terminals, RTUs, communication controllers and measurement instruments, to guarantee the safe and stable operation of the whole power grid.

Functions

1. Uninterrupted Power Backup It converts DC power from batteries into stable pure sine-wave AC power. Once the mains power fails, it switches to battery supply instantly with zero transfer time, preventing power loss for key electrical loads.

2. Voltage Stabilization & Power Quality Regulation The inverter module delivers regulated AC output to suppress voltage fluctuation, harmonic distortion and grid surge, supplying high-quality power to sensitive automation and protection devices.

3. Comprehensive Electrical Protection Built-in protection mechanisms cover overvoltage, undervoltage, overcurrent, short-circuit and overtemperature. It triggers local light alarms and remote fault signals when abnormalities occur.

4. Intelligent Monitoring & Management Equipped with an integrated monitoring unit. It real-timely displays operating parameters such as voltage, current and running status, supports fault recording and remote communication for centralized management.

5. High EMC Adaptability It fulfills strict electromagnetic compatibility requirements for power industry. Strong anti-interference capability guarantees stable operation under the harsh electromagnetic environment of substations and power plants.
