Smart 40 Amp Change Over Card | Single-Phase Automatic ATS Controller

Smart 40 Amp Change Over Card (Smart ATS Change Over 40A) is a control and automatic power transfer board designed to manage two power sources in single-phase systems. This card is intended for use in ATS panels, automatic change over, mains and generator power, mains and UPS, and other systems requiring automatic load transfer between two power sources.

This product automatically performs the transfer process between mains and backup source by monitoring input source status and using an adjustable time delay, reducing the need for operator intervention.

Operation of the 40 Amp Change Over Card

The Smart ATS card is designed to control two power sources. Normally, mains power is prioritized as the primary source.

In case of mains power failure, after detecting the input status and the set delay time, the system issues a load transfer command to the secondary source such as a generator or UPS.

When mains power returns, the card performs the load return process to mains after the specified delay time.

This operation allows power source transfer without manual switch toggling and with controlled timing.

Why use an ATS card in a change over panel?

Designing a change over panel using a dedicated control card can significantly simplify the control circuit.

The Smart Change Over card provides the control and timing of the transfer process in a compact unit for the panel manufacturer.

Advantages of using this board include:

• Reduced control circuit volume
• Simplified wiring
• Fewer auxiliary control components
• Faster panel installation
• Adjustable delay time
• Status indication of sources and outputs
• Suitable for single-phase ATS panels
• Mountable on panel rail

Features of the Smart 40 Amp Change Over Card

? Automatic control of two power sources

This card manages load transfer between mains and generator, mains and UPS, or two single-phase sources.

? Mains priority

When mains power is available, it is prioritized and load transfers to the main source after the set delay.

? Adjustable time delay

The system's delay time can be set according to panel application.

Currently, the delay range is 1 to 10 seconds for transfer processes.

? LED status indicators

LEDs provide quick visual status of inputs and outputs for the operator.

? Suitable wiring terminals

Appropriate terminals simplify installation and maintenance.

? Compact design

The board's size minimizes space inside the panel, allowing more compact panel designs.

? Rail mounting

Mechanical design allows installation on the panel's DIN rail.

Applications of the 40 Amp Change Over Card

This product can be used in systems requiring automatic transfer between two power sources, including:

• Generator panels

  For automatic load transfer between mains and generator in buildings, workshops, and industrial units.

• Single-phase ATS panels

  Suitable for manufacturing single-phase Automatic Transfer Switch panels.

• UPS and backup power

  Usable in systems employing UPS or backup power alongside mains.

• Residential buildings

  For emergency power systems requiring automatic source transfer.

• Shops and commercial centers

  Where power outages could halt equipment.

• Industrial equipment

  In control circuits and industrial equipment needing backup power.

Technical Specifications

Which panels is the 40 Amp Change Over Card suitable for?

The Smart ATS card can be used in the design of panels such as:

• Mains ↔ Generator

• Mains ↔ UPS

• Primary source ↔ Emergency source

• Two single-phase power inputs

Thus, panel manufacturers can implement source transfer control in an independent board using this card.

Difference between ATS card and manual change over

In manual change over, the operator must check the power source status and manually switch the transfer key.

In ATS systems, source status detection and load transfer are automatic.

The Smart Change Over card is designed for this purpose and can serve as the control core of single-phase ATS panel control circuits.

Suitable for panel manufacturers

A key application of this product is for panel builders and manufacturers of electrical and automation equipment.

Using a ready ATS board can reduce design and wiring time of control circuits and enable the construction of change over panels with more organized dimensions and layouts.

Also, in projects requiring multiple similar panels, using a standard control board simplifies assembly and production.
