King Power ATS Panel 400A–2000A Industrial Dual Power Automatic Transfer Cabinet

Product Description

ATS, short for Automatic Transfer Switch, is an intelligent dual power transfer cabinet that auto-switches power between municipal mains and standby generators without human operation. Our King Power ATS Panel series includes 400A, 800A, 1000A, 2000A heavy-duty models for industrial and commercial power backup.

This King Power automatic ATS cabinet instantly triggers genset power once grid electricity cuts off, and safely reverts to mains after power restoration to eliminate costly blackouts. Equipped with reliable control modules, full overload and short-circuit protection, our generator ATS panel fits factories, hospitals, malls and construction sites. Customizable 3-phase & 4-phase designs perfectly match all standby gensets, delivering stable emergency power distribution for continuous-load applications.

How King Power ATS Panel Works

This automatic transfer switch cabinet continuously monitors mains utility power and standby generator power 24/7.

1. Normal State: Load runs fully on stable city mains power; ATS keeps generator standby ready.

2. Power Failure Trigger: When mains cuts out, drops voltage or loses phases, the King Power ATS controller instantly sends auto-start signal to the genset.

3. Load Transfer: After the generator stabilizes voltage & frequency, the ATS safely disconnects mains then switches all loads to generator power within seconds.

4. Mains Recovery: Once grid power restores and stabilizes, the dual power ATS panel automatically shifts loads back to mains, then shuts down the generator after cooling delay.

5. Manual Override: Built-in manual switching mode for maintenance testing of the ATS transfer cabinet without power shutdown risks.

ATS Panel Application in Generator Sets

King Power ATS Panel 400A, 800A, 1000A, 2000A automatic dual power transfer cabinet serves as the core intelligent switching device for all generator set backup power systems. It acts as the critical connection between standby generator sets and building/industrial electrical loads, enabling automatic power switching, safe source management, and full system protection for genset power supply solutions.

1. Utility-to-Generator Systems

This is the standard working mode for most commercial and industrial emergency power systems. The King Power automatic dual power transfer cabinet connects the main utility grid and one or more standby generator sets. When utility power fails, experiences undervoltage or phase loss, the ATS panel automatically triggers the generator to start, transfers all electrical loads to genset power within seconds. Once municipal power restores and stabilizes, the device safely switches the load back to utility power and shuts down the generator intelligently, ensuring uninterrupted power supply for critical equipment.

2. Generator-to-Generator Systems

Ideal for remote installations, off-grid facilities and sites equipped with multiple generator sets, this King Power ATS cabinet supports dual-generator load management. The system can be professionally programmed for automatic backup operation: it will start the standby second generator immediately if the primary running generator fails. Additionally, it can periodically alternate the lead operating generator to balance running time, reduce mechanical wear, and extend the overall service life of the generator sets.

3. Multi-Source Redundant Power Systems

For high-reliability power demand scenarios, our heavy-duty ATS panel supports advanced multi-power-source configuration, including utility-generator-generator and utility-utility-generator combinations. The King Power ATS transfer cabinet intelligently sets power supply priorities, automatically identifies available power sources, and executes seamless switching between multiple power inputs. This multi-redundant design eliminates power outage risks and guarantees 24/7 continuous power for key infrastructure.

4. Integrated Power Protection & Intelligent Control

Integrated with high-performance circuit breakers, the King Power generator ATS panel provides professional overload and short-circuit protection to safeguard generators and electrical loads. It delivers full intelligent control functions, including automatic generator start/stop signal transmission, real-time system status monitoring, and intelligent alarm prompts for common faults such as generator fail-to-start and low oil pressure.

In short, the King Power ATS Panel is the intelligent core and switching hub of the entire genset emergency power system. It precisely manages safe, stable and timely power switching, ensuring generator sets can supply reliable emergency power whenever required.
