Features: The casing is made of aluminum and the product has good heat dissipation performance and corrosion resistance. All electronic components are selected according to military grade, and the whole circuit board is sealed with epoxy resin, which makes the product more resistant to moisture, corrosion and vibration. Applicable to the charging of various brand models 12V and 24V batteries, select 12V or 24V battery charging mode by jumper. Working voltage AC80~275V, working frequency 20~600Hz, can ensure that the engine can still be charged at low speed (idle speed). The electric energy of the diesel generator set can be directly charged to replace the fuselage charger. It can be used in a humid environment with a temperature of -40 ° C ~ +65 ° C and a relative humidity of 98 % RH without condensation. Allows the motor to be started while the utility is charging the battery. Applicable to lead-acid batteries, especially suitable for charging fully sealed solid wide temperature batteries. Can be self-stopping for constant current, constant voltage and turbulence of the battery. Soft start function: Since the system adopts the soft start design, it will not generate a large spark due to the power surge. In addition, when the charger is connected online, it will not interfere with the power supply system just after the power is turned on. Specification: Constant Current Fast Charge: When the voltage of the charged battery is lower than the set value (12V battery pack <12V, 24V battery pack <24V When the charger is charging the battery at the maximum constant current. Current Limiting: When the charged battery is nearly full (12V battery pack ≥12V, 24V battery pack ≥24V), the charging current is automatically limited. Turbulent Floating Charge: When the voltage of the charged battery reaches the floating charge setting value (12V battery pack is about 13.8V, 24V battery pack is about 27.6V), it will automatically switch to the floating state, that is, about the current 0.1 ~0.2A is charged (specifically related to the current power consumption of the powered device). Stop Charging: When the voltage of the charged battery reaches the filling set value (14V at 12V and 28V at 24V), the charge output is automatically turned off. Over-Current and Short-Circuit Protection: The product has perfect over-current and short-circuit protection. Due to the constant current characteristics of this product, when the battery capacity is large (the internal resistance is very small), the load is short-circuited or started during the mains charging period. In the case of a motor (the starting current is very large, it is close to a short circuit for the charger) and it will not be damaged. At the same time, due to this characteristic of the product, the charger does not need to be disconnected when the battery is used as a starting power source. The product panel is equipped with indicator lights (light-emitting diodes). When the indicators are in different colors, it represents the different working conditions of charging. Red: constant current fast charging phase, that is, the charging current is the rated maximum current value (including red when the output terminal is short-circuited); Yellow (red + green): the slip current floating phase (constant voltage), that is, the charging current begins to decrease, the current is larger when the lamp is red, and the current is less when it is greenish; Green: The battery is almost full (green when the output is open). Package List: 1 x Charger 1 x Users Manual Note: The product is specially designed for charging the battery. Since the output contains pulse components, it is not suitable for direct use as the power source of the electronic device when the battery is not connected. Otherwise, the electronic device may cause interference or even damage. If you do not have good anti-shock measures, it is not appropriate to install the charger directly on the diesel unit. The product should be protected from water or other liquids, and should be kept away from heat and thermal radiation.
