This Modular DC charger was custom-designed for the new substation of NGCP Power Grid Company in the Philippines. There are a large number of high-voltage switchgear in the substation, and it is equipped with power monitoring system and automatic operation device. NGCP Grid companies need to provide a stable DC operating power supply for these devices, sowe we recommend the smart maintenance-free Modular DC charger.

EverExceed customized the high-frequency rectified 125VDC200A Modular DC charger according to the customer's requirements. The operating system mainly adopts five high-frequency rectifier modules, and itis equipped with monitoring module and lightning surge protection; The output load with customized buck silicon chain (Max buck 35V, 50A). In addiction, The lP52 cabinet has functions such as temperature compensation, battery discharge test, and ground fault. This customized DC charger has better monitoring and protection functions, not only meetsthe power needs of the special equipment in the substation, but also monitors the working status, timely notifies the duty personnel of any fault warning,and ensures the normal operation of the equipment in the substation.

Custom design highlights:

More flexible:Custom-designed cabinets, 7-inch touch screen. lt can monitor equipment operating status and parameters.

More reliable: Configure the control switch of each rectifier module to effectively protect the circuit.

More affordable: With remote control, remote adjustment, telemetry. telecommunication functions and remote communication interface. Through the remote communication interface, the operating parameters of DC power supply system can be obtained in the remote place, and the operating status and fixed value can be set and modified through the interface to meet the requirements of power automation;
