SPECIFICATIONS –ANN3604 CHARGER
Totally Automatic Switch-Mode Battery Chargers
"Suitable for Li Ion and Li Polymer Batteries"
Summary: 36V， 4A Constant Current
- Automatic Cut-off and then true Float. Can be left connected indefinitely without harming the battery.
- Input Universal (90VAC~264VAC) - Suitable everywhere in the world.
- Many advance features described in this spec.
- Very small size and very lightweight
1. Switch-Mode Technology:
ANN\'s Battery Charger transforms the input into charger output using high Most of the battery chargers use linear technology， which convert the 115 VAC or 230VAC to 42 VDC at 60 Hz. This requires a large transformer， which has the disadvantage of lower efficiency resulting in higher heat generation， larger size and weight.
ANN\'s Battery Charger transforms the 90VAC~264VAC into 42 VDC at 100，000 Hz (1667 times faster than conventional charger) which requires a much smaller transformer and this results in a unit of smaller size， low weight and improved efficiency.
The ANN3604 uses sophisticated electronic circuitry with microchips. All present day computers use switch-mode technology.
2. International Safety Approvals & Listing:
CE
3. Input Requirements:
a)Universal 100~240VAC (Range 90VAC~264VAC). No switch to change AC voltage.
b)47 - 63 Hz
Input AC tolerance +/- 20%. This means ANN3604 will operate satisfactorily in areas where the input voltage is low.
This charger is also suitable for every part of the world. where the AC is 100VAC (Japan)， 115VAC (USA)， 230VAC (Europe) or 240VAC (UK).
4. Output:
4 Amps Constant Current @ 42Volts DC
a) Line Regulation @ Full Load 2%
b) Load Regulation 3%
c)Ripple Voltage: Very low
The peak-to-peak ripple voltage into a resistive load is less than 200mV for the output voltage above 42VDC.
5. Charging Cycle:
If the LED1 is ON ( Red )， it shows that input power is ON.
The charging curve is attached. The explanation of the charging cycle is as following.
Stages | Condition | Mode | Current | Voltage | LED Indication |
Stage 1 | Constant Current mode | CC mode | 4A | to 42V | Red |
Stage 2 | Constant Voltage mode | CV mode | Reduces from 0.4A | Holds at 42V | Red |
* CC mode = Constant current charge
* CV mode = Constant voltage charge
*** See Stage 2 description below
Stage 1: Constant Current Mode (CC):
The charger changes to constant current 4A. When the battery voltage reaches up to 42V， the charging stage changes from CC (Constant Current) to CV (Constant Voltage) mode.
Stage 2: Constant Voltage Mode (CV):
In this stage the voltage of each cell in the battery is equalized. The charger holds the battery at 42V and the current slowly reduces.
6. Two colors in one LED:
LED2 shows the charging status. The LED ON shows presence of input power. The bicolour LED shows Red when charging and changes to Green when the battery is fully charged.
7. Reliability:
a)Mean Time between failures (MTBF):
30，000 power-on-hours (POH) or greater. This translates into 10 years of everyday operation of 8 hours.
