GZ22010-3 is a self cooling (natural cooling) high-frequency switch charging module designed specifically for DC operation power systems, with an output voltage of 220V DC, a rated current of 10A, and a rated power of 2.2kW. The module adopts a fanless natural heat dissipation design, which poses a risk of fan failure and is suitable for power system scenarios with high requirements for operational reliability, low noise, and minimal maintenance, such as substations, distribution rooms, rail transit, data centers, hospitals, and communication base stations.
