Product Category: Power Distribution Equipment

This product is dedicated power‑distribution equipment designed for UPS uninterruptible power‑supply systems. Suitable for AC 380 V / 220 V low‑voltage distribution systems, it performs power distribution and protection on the upstream and downstream sides of UPS units. It enables isolation, distribution and protection between mains power and UPS power supply, and integrates multi‑layer protection against overload, short‑circuit, earth‑leakage, over‑voltage and under‑voltage. Built with a modular cabinet structure, it accommodates UPS systems of various power ratings. It delivers clean, stable uninterrupted power to critical loads such as servers, communication hardware and medical devices to ensure power‑supply safety.

‑ Short‑circuit Withstand Current: ≥ 50 kA ~ 100 kA
‑ Compliance Standards: GB 7251.1, IEC 61439‑1, GB/T 7260.3
‑ Protection Functions: Overload, short‑circuit, earth‑leakage, over‑voltage, under‑voltage and abnormal‑frequency protection
‑ Standard Features: UPS bypass transfer function, input‑output isolation
‑ Optional Functions: Energy metering, remote monitoring, smart meters, fire‑alarm interlock

① Custom‑engineered for UPS systems. Equipped with UPS bypass transfer capability, it enables mains bypass power supply during UPS maintenance so that connected loads remain powered without interruption.

② Comprehensive input‑output protection. It effectively isolates harmonics and surges from the mains side and supplies clean UPS‑conditioned power to safeguard connected equipment.

③ Modular construction. Circuits can be flexibly configured according to UPS power capacity and load quantity, satisfying UPS distribution requirements for data centres, computer rooms, medical facilities and other environments.

④ High short‑circuit withstand performance. It withstands high‑current impacts caused by UPS‑side short‑circuits for stable and reliable operation.

⑤ Optional intelligent monitoring. Real‑time tracking of UPS input‑output parameters including voltage, current and power, together with automatic abnormal‑condition alarms, supports unattended operation and maintenance.

Q1: What is the function of a UPS distribution cabinet?
A: A UPS distribution cabinet is purpose‑built distribution hardware for UPS systems. It handles power distribution, protection and transfer on the input and output sides of UPS units. It realizes mains‑UPS isolation and bypass switching, delivers stable and secure uninterrupted power to critical loads, and protects both the UPS unit and end‑user loads.

Q2: Does UPS bypass transfer function come supported?
A: Manual and automatic bypass transfer are supplied as standard. When the UPS undergoes maintenance or encounters faults, loads can be transferred to mains bypass supply to maintain continuous load operation.

Q3: What power‑range of UPS systems is compatible?
A: Models with rated current from 100 A to 3000 A can be custom‑manufactured, compatible with UPS systems ranging from 10 kVA to 2000 kVA. The distribution cabinet shall be selected to match the actual power rating of the deployed UPS.
