SM2420 LiFePO4 charger 1、Charger type Name：LiFePo4 25,6V 2A battery charger Type ：8 serials-2A 2、Charger parameter length 170mm width 70 mm height 47 mm weight 0.34 kg color Black Cooling way Natural convection Input volts 160V-240VAC input Input frequency 50Hz / 60Hz Appearance Working performance Maximum output voltage 29.2±0.5V Maximum output current 2A Charge type CC/CV Working Temperature 0°C to 50° C Storage temperature Working environment Humidity 95% concussion quiver guaranty -20°C to +65° C About 10g 10-55HZ,1.5mm(double amplitude) One year 3、 、Charge process The converting point is set to 3.65V, from CC to CV . 4． ．Instruction 1)Be sure that output wires of charger should be rightly connected with the battery, otherwise the charger will not work. Warning: Do not connect pole of the charger and battery in reversed condition. 2). There should be a good earth line after connected to AC power. Notice: When the battery is not connected, the charger do not work to output for the reason of safety. 3)When connected to the power, turn on the switch and the RUN LED will light on, then the charger begin to work and the fan start to rotate. 4). During charging, the RUN LED will light on, CHARGE LED will turn out to be red. CHARGE LED indicates the status of the charger. Red, yellow and green color show different charge status. The light will change color automatically for every status. 5)When CHARGE green light was on, charger will be turn off automatically and the fan will stop. 6)After charging finished, pull off the plug will disconnect the AC power. 5、 、simple failure treatments: ! warning！Maintenance and repair is limited to professionals only. NO. FAILURE Charger fail CAUSE to work, and indicator LED does Treatment approach not shine. Check whether the battery voltage is The battery voltage is too low or poor connect . contact . Input power connected is or not power connection is bad. The indicator LED shines,but charger Charger running too hot the power plug is loose. not,or the cooling fan is working correctly. The Charger is connected reversely to People Battery failed to be anode and cathode of mistake,need sent it back to repair. charged. the battery. Charger fault 4 Check AC power is normal or not，or Check the charger vent is clear or fail to work 3 voltage. check the charger and the battery is connected or in pool 1 2 below the discharge protection The Status indicator Battery voltage level is LED only over charging voltage of lighting for a short the charger or a the of time then charger battery capacity is too auto-off. low . is themselves made the If charger internal wires fault, then need send it back to repair. First check the battery voltage level, and then check the battery is aging. Remark: If the handle is invalid, please contact our company in time to resolve. 、 guaranty 6、 Our chargers could be replaced within two months if there are any quality problems.
