Series:
The HD22020-2 is a product model from EMERSON, but it is not explicitly divided into a specific family.
Features:
High efficiency: The use of advanced high frequency switching power supply technology, efficiency greater than 91%, power factor greater than 0.90.
Safety: With electromagnetic compatibility and safety measures, in line with IEC standards.
Stability: The output ripple is greatly reduced, and the flow sharing between modules adopts advanced low-difference autonomous flow sharing technology.
Protection: It has perfect protection and alarm functions, including input over/under voltage, phase loss, output over/under voltage, etc.
Intelligent: The internal monitoring board not only monitors the operation of the control module, but also has the functions of remote control, telemetry, remote communication and remote adjustment.
Functions:
HD22020-2 DC power supply charging module is mainly used to protect power systems, railway electrification systems, communication systems in various electrical equipment (such as transformers, switches, capacitors, stoppers, transformers, generators, electric power, power cables, etc.) from atmospheric overvoltage, current operating overvoltage (current) and power frequency transient overvoltage (current) damage.
The module is suitable for the DC screen of the distribution room for charging, and it is also called the module of the DC screen of the high voltage room.
