Generator Model: 3634778 charger is the use of high-frequency power supply technology ESD5500E, the use of advanced intelligent charging technology for dynamic adjustment. It uses a constant-current / constant voltage / constant current smart three-stage charging a small way, with high charging efficiency, simple operation ESD5550, light weight, ESD, small size and other characteristics. Charger is capable of Shanghai Electric Equipment Co., Ltd. Shi design, machine internal power devices (such as transformers, inductors, capacitors, etc.) are larger, there is generally less noise in the larger load operation, but the models in harsh Grid-resistant strong anti-environmental conditions of performance, reliability and stability than high-frequency machine is strong. Charging Model: volvo high frequency machine is a microprocessor (CPU microarrays) as process control center, is complicated hardware analog circuit programming the microprocessor to the way the software program to control the operation of UPS Thus, the volume greatly reduced, greatly reduced weight, low manufacturing costs, the price is relatively low. High Frequency inverter frequency generally 20KHZ above, but high-frequency machine in harsh environmental conditions and poor grid tolerance, more suitable the grid more stable and less dust, temperature / humidity appropriate environment.
