ATS Control Box

Material: carbon steel
Color: Gray
Place of Origin: Shanxi, China
Application: Industrial
Product Category: Control Box

This product is dedicated control equipment for Automatic Transfer Switch (ATS). Compatible with AC 220 V / 380 V low‑voltage power distribution systems, it controls automatic transfer between two power sources and enables intelligent switching between mains‑to‑mains power or mains‑to‑generator power. It integrates functions including voltage monitoring, time‑delayed transfer and fault alarm. Compact in size and easy to install, it suits dual‑power‑supply retrofits for various small distribution boxes and control cabinets, ensuring power‑supply continuity for critical loads.

‑ Rated Voltage: AC 220 V / 380 V (optional)
‑ Control Supply Voltage: AC 220 V
‑ Transfer Time: 1 ~ 60 seconds (adjustable)
‑ Monitoring Functions: Over‑voltage, under‑voltage and phase‑loss detection
‑ Transfer Modes: Auto‑return after restoration / non‑auto‑return after transfer
‑ Interlock: Mechanical plus electrical dual interlock
‑ Ingress Protection Rating: IP30
‑ Compliance Standards: IEC 60947‑6‑1, GB 14048.6
‑ Optional Features: Fire‑alarm interlock, remote communication interface

① Compact footprint for easy installation. It can be mounted directly inside distribution boxes and control cabinets to satisfy dual‑power transfer requirements of small‑size equipment.

② Intelligent voltage monitoring. Real‑time status tracking for both power sources triggers automatic transfer upon abnormalities without manual intervention to maintain uninterrupted power supply.

③ Multiple configurable transfer modes. Either auto‑return or non‑auto‑return operation can be set to match power‑supply requirements of different working conditions.

④ Dual interlock protection. Combined mechanical and electrical interlocks prevent simultaneous closing of both power sources, eliminating short‑circuit risks and securing equipment safety.

⑤ Wide operating‑voltage range. It tolerates grid voltage fluctuations for stable performance.

Small‑scale loads requiring dual‑power‑supply backup, such as small computer rooms, office equipment, household critical devices, small retail shops, compact medical equipment, communication terminal units, fire emergency lighting and surveillance systems.

Q1: What is the function of an ATS control box?
A: The ATS control box governs the automatic transfer switch and continuously monitors the status of two incoming power sources. When the preferred power source fails, it automatically switches over to the standby source to guarantee uninterrupted power for critical loads with no manual operation required.

Q2: Does it support manual transfer?
A: Yes. Both automatic and manual modes are available. Manual mode can be activated for emergency operation in case of faults within automatic mode.

Q3: What size of ATS switch is compatible?
A: It works with most standard‑model ATS automatic transfer switches up to 630 A rated current. The control box shall be selected to match the specifications of the connected ATS device.
