Military AC / DC dual input charging machine power supply

1. Input voltage:

a) AC voltage range: 90 ~ 264Vac, 47 ~ 63Hz;

b) DC voltage range: 10 ~ 32vdc;

2. Output voltage: charging voltage 29.4vdc (battery capacity 4.4ah, voltage output range 20V ~ 29.4V);

3. Charging current

a) Standard current: 0.2ita ~ 0.4ita;

b) Fast current: 0.5ita ~ 0.8ita;

c) Maintenance current: 0.1ita ~ 0.2ita.

Note: ITA ＝ c5ah/1h, C5 refers to the amount of electricity that the battery should provide when it is discharged to the termination voltage at a rate of 5h at an ambient temperature of 23 ℃± 2 ℃.

4. Charging efficiency: under the condition of -40 ℃ ~ 55 ℃, the charging effect is as follows:

a) Standard charging time ≤ 180min, battery capacity ≥ 95%;

b) Fast charging time ≤ 120min, battery capacity ≥ 90%.

Note: the charging efficiency is tested on normal batteries with an initial voltage lower than 17.5V, excluding abnormal batteries
