Automatic transfer switch panels from 32 A to 3200 A
ATS panel- Auto Change over working:
ATS (Auto Change over panel ) using for control generator set start-stop sequence in with the availability of electrical power system. When power fails in residential building and hospitals emergency generator is critical things. AMF working as automatic transfer switch in standby power system.
They work by stopping the backup generator from become a source of electrical power until start on for temporary power. When the generator is ready to perform, the switches the emergency power to the load. The ATS then commands the generator to shut down when the utility power is restored.
A unique method of meeting fire safety Building Regulations. our Dual Mains Automatic Changeover Panel has been specifically formulated for buildings with duplicate power supplies. The Changeover automatically switches mains electricity from one supply to another. in the event of a fire or mains power failure, to ensure continuous of supply to firefighting lifts.
ATS controller
An ATS controllers used to control a diesel generator connected to a load for emergency power in a standby load. ATS means Automatic Transfer Switch that is used for auto transfer panels. An ATS controller governs a transfer switch via relays and software subroutines.
In order to suit all specifications of our clients. Our electric control panel Manufactured as per Indian standard using best quality raw material and sophisticated technology. These board use circuit breakers or motorized changeover switches to power your infrastructure during a mains failure.
We supply changeover systems from 32A for the smallest backup systems to 3200A ACB-based synchronizing for much larger installations.
Finally, we are growing as top auto change over panel manufacturer in India.
An auto changeover panel (automatic transfer switch, ATS) transfers the load between two supplies — mains and DG, two DISCOM feeders, two transformers or grid and solar-plus-storage — when the preferred source fails or drifts outside limits, and transfers back when it recovers. Accu-Panels Energy manufactures contactor, MCCB and ACB-based changeover panels from 32 A to 3200 A on its CPRI type-tested IEC 61439 platform in Ahmedabad, in open-transition, closed-transition and delayed-transition schemes.
- Auto / manual / off selector with source-available and source-on-load indication
- Adjustable transfer and re-transfer delays; DG start signal and cool-down output for AMF operation
- Electrical and mechanical interlocking so both sources can never be paralleled (open transition)
- Motorised MCCB / ACB changeover with under-voltage releases for higher ratings
- Bypass-isolation option for maintenance without load interruption
- Metering of both sources; Modbus and BMS contacts on request
- IEC 61439-1/2 assembly; transfer switching equipment per IEC 60947-6-1; CPRI type-tested design
- 415 V AC, 3-phase 4-wire, 50 Hz; 3-pole or 4-pole (switched neutral) changeover
- 32 A to 630 A contactor-based; 100 A to 3200 A MCCB / ACB-based
- Short-time withstand 25 kA to 65 kA for 1 s
- IP42 / IP54 indoor, IP55 / IP65 outdoor (IEC 60529)
- 1.6 / 2.0 mm CRCA, 7-tank pre-treatment, powder coated; wall- or floor-mounted
Choosing the transfer scheme
Open transition (break-before-make) is the standard and simplest scheme: a brief interruption of 100 ms to a few seconds. Delayed transition adds an intentional off-time so motor loads decay before reconnection. Closed transition (make-before-break) parallels the two sources for under 100 ms for a no-break transfer, which requires synchronising check — see our synchronising panels. We recommend the scheme from your load type and the utility’s paralleling rules.
Frequently asked questions
What is the difference between an auto changeover panel and an AMF panel?
The changeover panel only switches between two available sources. An AMF panel also starts, monitors and stops the DG engine. Many installations combine both functions in one panel.
Do I need a 4-pole changeover?
Yes when the two sources have separate neutrals or earthing systems (typical for DG and mains); a switched neutral prevents circulating currents and nuisance RCD tripping.
Can the panel be operated manually during maintenance?
Yes. Manual mode and, for critical loads, a bypass-isolation arrangement allow transfer and servicing without dropping the load.
Lead time?
2 to 4 weeks for contactor-based panels, 4 to 6 weeks for ACB-based panels after drawing approval.
