    Tips: High frequency plating rectifier in power system

    In the power system, the DC power supply is used as a power source for relay protection, automatic devices, control operation circuits, lights, sound signals, and accident lighting. It is a relatively important equipment in power plants and substations. Accidents caused by DC power supply failures occur from time to time, so the reliability and stability of the DC power supply have high requirements. In recent years, many DC power supply manufacturers have introduced intelligent high-frequency plating rectifier switching power supplies. This power supply system has many advantages: Safety, reliability, high degree of automation, smaller size and weight, high overall efficiency, and low noise. To meet the needs of power grid development, it is worth promoting. Therefore, the DC power supply used in the power system is gradually changing from the traditional phase-controlled power supply to the modular high-frequency electroplating rectifier switching power supply.

    The working principle of the high-frequency plating rectifier switching power supply is: AC power is connected to the rectifier module, converted into DC after filtering and three-phase full-wave rectifier, and then connected to a high-frequency inverter circuit to convert DC to high-frequency AC. Finally, after passing through the high-frequency transformer, rectifier bridge and filter, the output is smooth DC. This high-frequency switching power supply is mainly composed of a high-frequency switching charging module, a centralized monitor and a battery pack, etc., wherein the charging module and the centralized monitor have a built-in microprocessor, and the degree of intelligence is high. When the high-frequency switching power supply system is running normally, the output of the charger runs in parallel with the battery pack to supply power to the regular load.

    Existing reviews of 4000A Three Phase Plating Rectifier, 480V AC to 24V DC
    Some power supply information I want to know
    We are still designing a system trying to utilize one of these models. I believe we will use the 480V AC 3ph 60hz input >> 36V DC 2000A water cooled power supply. What I still need to know is the following:
    - What is the maximum water outlet temperature permissable to run the unit?
    - Is there a temperature the unit will shut down?
    - What are the water inlet/outlet port sizes?
    - Can the unit be run at a lower water flow rate (~5gpm) if the inlet temperature is constantly controlled to~20deg C?
    - What is the actual input amperage rating of this unit at 480V AC under full load?

    1. The maximum water outlet temperature permissable to run the unit is 35°C.
    2. The equipment has temperature protection, and the power supply will automatically
    stop when the outlet water temperature is 75 degrees Celsius.
    3. Outlet port size DN20.
    4. If the inlet temperature is constantly controlled to~20deg C, the unit can run at a lower water flow rate.
    5. 480V AC actual input rated maximum current 95A.
    I have another question about 4000A 3 phase plating rectifier
    I had one remaining question regarding this 4000A three phase plating rectifier. The product page has a value for output frequency, but my use for the device requires continuous output. Is that possible with this device or will there always be some sort of frequency associated with the output?
    From: Zleahv | Date: 02/09/2021
    Was this review helpful? Yes No (0/0)
    ATO Responded
    1. If it is a conventional DC voltage output, there is no frequency output.
    2. If the requirement is pulse frequency output, we can customize the pulse frequency output according to your requirements. In this case, you need to tell us the range of the output pulse frequency.
