SPECIFICATIONS ZY54.6V10A CHARGER
Totally Automatic Switch-Mode Battery Chargers
Summary: 54.6V10A Constant Current
- Automatic Cut-off and then true Float. Can be left connected indefinitely without harming the battery.
- Input Universal (170VAC~264VAC) - Suitable everywhere in the world.
- Many advance features described in this spec.
- Very small size and very lightweight
- Explanation of the Features:
The advance technology of the OEM Battery Chargers is fundamentally different from other battery chargers. The conventional linear battery charger is an electrical device whereas the ZY54.6V10A is a lightweight sophisticated electronic device.
1. Switch-Mode Technology:
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 54.6VDC at 60 Hz. This requires a large transformer, which has the disadvantage of lower efficiency resulting in higher heat generation, larger size and weight.
The Battery Charger transforms the 90VAC~264VAC into 54.6VDC at 55,000 Hz which requires a much smaller transformer and this results in a unit of smaller size, low weight and improved efficiency.
The ZY54.6V10A uses sophisticated electronic circuitry with microchips. All present day computers use switch-mode technology.
2. Input Requirements:
a)Universal 170~240VAC AC voltage.
b)47 - 63 Hz
Input AC tolerance +/- 20%. This means ZY54.6V10A 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).
3. Output:
10Amps Constant Current @ 54.6Volts 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 150mV for
the output voltage above 54.6VDC.
- Charging Cycle:
If the LED is ON ( Red ), it shows that input power is ON.
The charging curve is attached. The explanation of the charging cycle is as following.

*** See Stage 2 description below
Stage 1: Constant Current Mode (CC):
The charger changes to constant current 10A. When the battery voltage reaches up to 54.6V, 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 54.6V and the current slowly reduces.
5. Two colors in one LED:
LED 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.
6. 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.
