When selecting a high-power DC power supply, note the following:

1.220V and 110V DC systems shall use battery packs. For dc systems up to 48V, batteries can be used.

500kw load bank
 

2. For auxiliary workshops with long power supply distance, when DC power is needed, dc system should be set independently.

3. Normally, the battery group should operate in floating charge mode.

4. The lead acid battery group is not suitable for installing end batteries. Chrome-nickel alkaline battery should reduce the number of terminal cells.

5. Nominal voltage of DC system: 110V should be used for DC system designed for load control; The DC system for power load should use 220V. The DC system for controlling load and power load and supplying power adopts 220V.

6. Charging device: should meet the charging and floating charging requirements of the battery; Can meet long-term continuous work needs; The charging device should have the performance of stabilizing voltage, stabilizing current and limiting current; The charging device shall have the functions of automatic and manual float charging, equalization charging, steady current charging, current limiting charging, etc.
