ELO Full Automatic SMPS Battery Charger provides the batteries to be charged in the most optimum way without exceeding the charge voltage limits. Charger reduces the charge current automatically when the charge voltage limit has been reached and switches to trickle charge mode only to compensate for battery self-discharge. Thus, the battery always stays at the highest level of charge. The unique design of the unit increases the efficiency up to 85% while reducing weight and total heat dissipation in comparison to linear chargers.

CURRENT LIMITATION
ELO Full Automatic SMPS Battery Charger incorporates a current limiter. The charger limits the current at 5A in the case of any defective/shorted cell battery being connected. The charger keeps voltage reduced and continues to charge at 5A until the batteries reach the normal charge level. The charge current reduces proportionally as the battery voltage increases. The charge status can be observed from the "Charge Status LED" on the front panel. The red LED indicates that the unit is being charged, while green LED signifies full charge.
 
SHORT CIRCUIT PROTECTION
Due to its short circuit protection, the charger will not give an output unless the battery is properly connected. Consequently, if the (+) terminal and the (-) terminals are short circuited, there will be no negative consequences since there is no output. The charger begins to give output when the battery is correctly connected. When one of the terminals are removed from the battery, the charger cuts off the output voltage automatically.
 
CROSS CONNECTION
The unit has the feature of protecting the battery when terminals are reversely connected to the charger, also known as cross connection. Therefore, if the battery terminals are accidentally connected in a reverse manner, the charger will not give an output. This way a possible damage to the charger or the battery is avoided. The "Cross Connection Warning" red LED is lit in case of reverse polarity connection.  The charger begins to give output only when the terminals are connected correctly. Again, the charger ceases to give output when terminals are shorted or cross connected. The charger and the battery will not be damaged even in the case of battery terminals being reversely connected to the charger cables.
 
OVERHEAT PROTECTION
In cases which many parallel batteries or a battery which is below the permitted discharge values or a faulty battery connected, there will be excessive heating due to the prolonged drawing of maximum charge value of 5A from the charger. In the case of overheating of the electronic components, the charger switches to excessive heat protection mode. When the heat decreases the charger switches back to charging mode according to the need of the battery.
 
INPUT VOLTAGE RANGE
The input voltage needed for the unit is 220 VAC. However, the unit is designed to operate normally in order to compensate the fluctuations between 176 and 264V of voltage input.
