1. Features
Optimised operating software
When charging or discharging, A8 has an 'AUTO' function that sets the feeding current
automatically. Especially for Lithium batteries, it can prevent the over-charging can lead to
an explosion by users fault. Every program in the unit is controlled with mutual links and
communication for every possible error so it introduces a maximum safety. These can be set
at users option.
Special recharge plugsport for receiver, transmitter and igniter charger. And for
frequently used charger port such as multi purpose crocodile pin etc.
A8 provides most convenient balance charge port for Lithium batteries, with separated
3,4,5,6 7,8 charge port, and external reverse connector.
High-power and high-performance circuit
A8 employs the circuit that has maximum output power of 150W. As a result it can
charge or discharge up to 27 cells of NiCd/NiMH and 8 series of Lithium batteries with
maximum current of 7.0A. Furthermore the cooling system is so efficient that can hold such
a power without any trouble of running the CPU or the operating program.
Individual voltage bala ncer for Lithium batteries inside
A8 has an individual-cell-voltage balancer inside.This does not require any extra
balancer separately when charging Lithium batteries(Lilo/LiPO/LiFe) for cell voltage
balancing.
Balance individual cells on discharge
A8 also can monitor and balance individual cells of the Lithium battery pack during
the discharge process. If the voltage of any one cell varies abnormally, the process will be
stopped with the error message.
Accept various types of Lithium battery
A8 can accept three types of Lithium batterles- Lilo, LiPo and LiFe. They have different
characteristics by their chemistry. You can select any one of them that you are going to
process before the job. For their specifications, refer 'Warnings and safety notes' section.
Lithium battery 'Fast' and 'Storage' mode
You can charge Lithium battery for special purposes. 'Fast' charge reduces the charging
time of Lithium battery and 'Storage' mode controls the final voltage of the battery to be suit
for long time storage.
Maximum safety
Delta-peak sensitivity: The automatic charge termination program works on the principle
of the Delta-peak voltage detection.(NiCd/NiMH)
Auto-charge current limit: When charging NiCd or NiMH at 'AUTO' current mode, you
can set the upper limit of change current to avoid from high current charging. This is very
useful when charging the low impedance and small capacity NiMH battery in 'AUTO' mode.
Capacity limit: The changing capacity always calculated by multiple of the charging
current and time. If the charging capacity exceeds the limit the process will be terminated
automatically when you set the maximum value.
Temperature limit: The temperature of the battery on charging will rise by its internal
chemical reaction. If you set the limit of temperature the process will be expired forcibly
when the limit has reached.
