Description
1. Connect the charger sytem to a wall receptacle and make sure the connection is tight.
2. Connect the DC cables to the charger before making any connection to the battery.
3. Please be sure the polarity is correct before turn on the charger: red terminal<=>red
cable<=>battery(+); rlack terminal<=> black cable<=>battery(-).
4. Turn on th power that is located at the rear panel, the red LED lights on and bi-color LED will indicate the charger's stage. On the LCD(digital meter) screen will show the charger's stage and the battery's level (or O/P voltage).
5. The charger is designed in aluminum housing as its heat sink, while charging a battery, the case's temperature willl rise to about 50°C, please be careful when touching the unit.
6. Please ensure to place the charger in a well-ventilated and dry environment.
Protection Functions
- Short-circuit Protection: Charger O/P cut-off automatically when short circuit.
- Overload Protection: Charger O/P current-limited automatically when overload.
- Reverse Polarity Protection: Charger O/P cut-off automatically when battery reverse connection.
- Automatic multi-rate charging function: Equalizing charge, Floating charge and options for Pulse charge and Pre-charge (for WHC-XXXXD only).
- Unique LCD (or digital meter) Display: Indicating both charger status and battery level (or voltage, current, capacity, timer and charging time).
- 3 LED Display: Red(power), green(floating charge) & orange(equalizer charge).
- Can be used as DC power supply when connect the device in a parallel with batteries, also function as an UPS.
- Aluminium housing take elegant, anti-corrosion and compact all into account.
4 stage charge cycles: Pre-Charge, Equalizing Constant Current, Constant Voltage, Pulse Charge & Float Charge. Digital meter indicating numerous charger status and battery level, LED display. Short-circuit, overload, reversed polarity protections. When the charger is in Equalizing stage, cooling fan speeds up; when in Float charging stage, cooling fan slows down or stop spinning. Manual Built-in Pulse Charging Switch. Twin outputs for charging batteries independently.
