When it comes to automatic transfer switches, we use the acronym ATS. In other words, an ATS panel is a metal cabinet that hosts a transfer switch of a suitable size for your standby generator. The ATS controller with its ancillary instruments is normally placed on the metal cabinet's door.
Protect your business in case of a power outage
The automatic transfer switch panel is conveniently tasked with driving the switching of your load to mains or generators. The power configuration and general arrangement are the same for all panels. The input-output lines for the engine connection and ancillary equipment depend on the type of controller fitted to the panel. The automatic transfer switch panel continuously monitors the status of the utility power. You can set low and high limits for Voltage and Frequency. In other words, when the voltage and the frequency are within limits, the automatic transfer switch panel connects the load to the utility power.
If the voltage drops below the lower limit (or rises above the high limit), the automatic transfer switch panel will disable the utility power circuit. This prevents, after a programmable delay, severe damage to your load. If the failure persists over the programmed time, the ATS panel will instruct the generator to start.
Using our ATS panels you can avoid purchasing brand-new expensive automatic generators. Purchase a low-cost second-hand generator. You will get a state-of-art backup power system.
With or without an electronic controller!

(contactor changeover)
Our panels feature two contactors with mechanical interlocks. You will achieve a granular control monitoring and protection of your building's electrical system.
The contactors, usually four-pole, are coil-operated switches that close a circuit when the excitation coil is supplied with alternating 230V.

(motorized changeover)
These panels offer an internal manual override. This will allow you to activate manually the changeover switch. These panels are recommended when you have to manage large power involving high currents. You can connect generators without a built-in controller.
The motorized ATS panel offers superior performance when it is too big currents. Starting from 80kVA we use the BeK3 controller that features CANbus and MODbus remote control monitoring options. You can connect RS485 drivers to get GSM and TCP/ip monitoring. You can purchase separately the MODEM and TCP/IP server

An automatic transfer switch is one piece of electrical equipment capable of controlling a backup generator.
BEFORE CONNECTING YOUR LOAD
The automatic transfer switch panel checks the quality of the generator voltage and frequency. The ATS panel will connect the generator circuit to your load when the parameters are within programmed limits. During a power outage, the automatic transfer switch panel monitors the utility power. When the utility power parameters return within the programmed settings, the automatic transfer switch panel will transfer the load to utility power. This will happen after a delay that will ensure that the utility power is in stable conditions. The engine will run offload after connecting your load to the utility power. Then, the engine will stop and the automatic transfer switch panel is ready for a new power outage.
The automatic transfer switch panel wiring diagram
In the following wiring diagram, you can see all the details about an automatic transfer switch panel. The size of the wires, contactors, transfer switches or changeover, cabinet size, and terminal blocks, depend on power rating.

What kind of generator can you use with our automatic transfer switch?
Our automatic transfer switch panels support all engines and generators. You can upgrade a second-hand generator by using our automatic transfer switch panel.
The internal interface board of our automatic transfer switch panels features all relays that interface with all kinds of engines. In other words, you do not need any controller fitted with your generator. Our automatic transfer switch panel will take care to control all functions. If you own an old generator, check the electric start and stop. In the worst case, you will use two automotive relays to interface with the engine as shown in the below picture
CAN I MAKE MY OWN ATS PANEL?
Yes, you can. We offer to you a wide range of Automatic Mains Failure and Automatic Transfer Switch Controllers. Visit our website now and choose the product suitable for your application.
HOW TO BUILD AN ATS PANEL TUTORIAL
Why does using our automatic transfer switch panel exponentially increase the long-term reliability of your standby generator?
This is because of a big misunderstanding about overvoltages and flashes of lightning. The low-cost controllers on the market are erroneously placed on the frame of generators. This forces the user to connect the wires of the mains to the controller inside the generator. Despite all your efforts, you will never get protection from the electronic boards. The wires' parasitic capacitance cannot be eliminated.
NEVER DO LIKE THIS WITH AN AUTOMATIC TRANSFER SWITCH
It is a money-saving practice to connect the cables of the mains directly to the AMF controller.
This is an unsafe practice. Forget about it!
CONNECT THE ATS PANEL IN THIS WAY
The overvoltages will never hit your generator.
The controller Be242 will protect your generator from mains surges, You can optionally use your auto-start module, or use the normal input-output lines of the Be242 controller.
How to use the automatic transfer switch?
Our automatic transfer switch panels are based on the user-friendly Be242 controller. In this example, we describe the way to use the Be242 controller.
Push the AUTO button. The Be242 controller will automatically manage all tasks. The MANUAL button always overrides the automatic mode. The basic protections will always be active. This prevents dangerous situations. The Be242 is a combined ATS, and generator controller. It offers a large flexibility of use. You can manually start and stop the engine. You can manually control the changeover switch.
THE LOAD IS CONNECTED TO THE MAINS
THE LOAD IS CONNECTED TO THE GENERATOR
AUTO MODE OF OPERATION
The Be242 must be programmed in the factory according to the panel size. To adapt the panel to your application you may need to program some settings. The programming is easy. Use the navigation buttons on the controller's front panel. You can download the following user's manual:
ATS CONTROLLER INSTALLATION MANUAL
This panel supports all kinds of engines. The internal interface board features all the relays you need to start and stop the engine. You can connect the automatic transfer switch panel to a generator fitted with any auto-start module.
How do you connect two generators in a standby configuration?
Program the configurable inputs and outputs to define the start priority. This is the typical duel generator configuration.
Serve two separate buildings with one standby generator.
Forget to use complex PLC when you have to make this kind of application. It is about the DAUL-LOAD configuration, You program this function into the adjustable input-output of the controller.
