(Model NL07C-25HT)
DESCRIPTION:
NL07C-25HT is a smart charger specially designed for Li-ion battery pack composed cells in series.
ELECTRICAL SPECIFICATIONS:
1. Input: I00-240VAC, 50/60 Hz. Output: 29.05V± 0.2V 2.5Adc ± 10%
2. Charger output: The charger is preset by factory for charging 7 cells Li-ion battery pack.
Its charging mode:
(1) Constant current (CC) mode : at beginning of charging, an 2.5Adc±10% (1(ave))
constant charging current to charge the pack until the pack voltage reaches to
29.05V± 0.2V.
(2) Constant Voltage (CV) mode : the output will keep 29.05V±0.2V constant through
the end of charging.
(3) Pre-charge state: When battery voltage is lower than 21V±1V. will start the
