Low Voltage Switchgear & Distribution Panels
EMDB-ATS / MTS (Emergency Power Automatic/Manual Transfer Switch Distribution Board) is an intelligent transfer system specifically designed for critical power applications, providing automatic or manual switching between main power and backup power sources. This product ensures seamless transition to backup power during main power failure, guaranteeing continuous power supply for critical loads. It is suitable for hospitals, data centers, communication base stations, and other venues with extremely high requirements for power supply continuity.

Q1：What is the main difference between the ATS and MTS in this distribution board?
A: The ATS (Automatic Transfer Switch) automatically detects a power failure and switches to the emergency source (like a generator) within milliseconds. The MTS (Manual Transfer Switch) requires an operator to manually toggle the power source, offering a cost-effective solution for non-critical loads where immediate switching isn't vital.
Q2：What is the typical switching time (Transfer Time) of your ATS?
A: Our ATS units typically achieve a transfer time of less than 100ms (standard range 50ms-250ms depending on the controller), ensuring minimal interruption to your critical equipment during power transitions.
Q3：Does the panel include mechanical and electrical interlocking?
A: Yes, safety is our priority. Our EMDB units are equipped with both mechanical and electrical interlocks to prevent the simultaneous connection of both power sources, eliminating the risk of short circuits or back-feeding.
Q4：Can this board integrate with a Diesel Generator set?
A: Absolutely. Our ATS controllers feature Remote Start/Stop signals. When the utility power fails, the panel sends a dry contact signal to start the generator and switches the load once the voltage and frequency are stable.
Q5：What brands of switching components do you use?
A: We use world-class components such as ABB, Schneider, Socomec, or our high-quality domestic brands (e.g., Aisikai) known for high breaking capacity and long electrical life, depending on your project specifications.
Q6：Do you offer 3-pole or 4-pole transfer switches?
A: We provide both 3-Pole and 4-Pole configurations. A 4-pole switch is often recommended for systems requiring complete neutral isolation to avoid ground loop currents and ensure safety during maintenance.
Q7：What are the enclosure options for the EMDB-ATS/MTS?
A: We offer enclosures made of cold-rolled steel with powder coating (RAL 7035) or stainless steel (304/316) for corrosive environments. Protection ratings range from IP42 for indoor utility rooms to IP65 for outdoor emergency power setups.
Q8：Does the panel support manual override in case of controller failure?
A: Yes. Our ATS units include a manual operation handle. In the unlikely event of an electronic controller failure, authorized personnel can safely switch the power source manually using the provided handle.
Q9：What tests are conducted to ensure reliability before shipping?
A: Each unit undergoes a comprehensive functional test, including multiple cycles of simulated power failure, automatic transfer, return-to-utility tests, and dielectric strength tests. We ensure the logic is 100% accurate before it leaves our factory.
Q10：Can you provide the wiring diagrams and technical manuals in English?
A: Yes, all our documentation—including electrical schematics (CAD/PDF), user manuals, and labeling—is provided in professional English. This ensures your local electrical team can install and maintain the board without any language barriers.
