The T4812M converter module is specially designed for distributed power systems, and its high power density reduces the size of the product. The high power density and forward airflow design reduce the product volume and increase scalability. The product offers many features, including RS485 interface, which make it have a wide range of application areas. The above characteristics make this product a wise choice for you.

Function

Output overvoltage shutdown

If the output voltage exceeds the preset value, the rectifier will automatically shut down. The overvoltage shutdown point is reduced by approximately 1V at full load to ensure smooth shutdown of the rectifier during overvoltage. The overvoltage cut-off voltage can

be adjusted and is set at the factory.

Hot Plug

When performing rapid module insertion and removal, the module should be fully discharged internally to ensure that the automatic restart of the module can be completed smoothly. The method to ensure sufficient discharge inside the power supply is to observe the rotation of the fan after unplugging the module, and only insert the module again after the fan stops rotating.

Inrush current

At the start-up of the rectifier, the peak value of the input impulse current is not greater than twice the maximum input current. The output voltage and current will slowly rise from zero during start-up, providing a soft load characteristic for the equipment.

Over temperature protection characteristics

When the maximum operating temperature is reached inside the rectifier, the rectifier will gradually reduce the output current to lower its internal temperature. In extreme environments, even if the output current is reduced, the internal temperature of the rectifier may continue to rise. In this case, the rectifier will be completely turned off and will automatically restart after the internal temperature returns to normal.

When operating at full load, the operating temperature of the rectifier is -33 to+55 ℃, with a maximum operating temperature of+65 ℃. The rectifier operates at a reduced load at a temperature of+55 to+65 ℃ to maintain its internal temperature within the normal range.

Reverse polarity protection

The rectifier has reverse polarity protection fuses and diodes inside, which can provide timely and effective protection.

Current Sharing

When multiple rectifiers are used in the system, the rectifiers will effectively balance the current. Each rectifier's hardware monitors the current bus voltage and adjusts its own output current to complement other rectifiers.

Fan cooling

The rectifier continuously monitors its internal temperature, ambient temperature, and output current to adjust the fan speed. This fan speed control reduces noise and dust accumulation. If a fan stops working and cannot be restarted by the microcomputer, a fan failure alarm signal will be issued, and the output current of the rectifier will decrease.
