MAGNUM AGRI 25 12/24V GEL Automatic Rectifier

MAGNUM AGRI 25 12/24V GEL Automatic Rectifier The AGRI 25 12/24V AUTOMATIC charger from MAGNUM is an inverter solidly built device with an intelligent charging process. It automatically detects the voltage of a 12 or 24V battery, and is designed for ordinary and maintenance charging of batteries: lead-acid batteries of open or closed type (e.g. WET - with liquid electrolyte, GEL - with gel electrolyte, or AGM - with electrolyte-absorbing mat).The AGRI 25 12/24V AUTOMATIC charger operates in a four-stage mode, this is especially important for batteries that are significantly discharged, or not used for a long time.Pre-charging is especially important for batteries that are significantly discharged, or not used for a long time. In this mode, the charger excites the battery with a low current in order to safely restore the battery to the parameters that allow charging in normal mode. Then the charger will automatically proceed to charging according to the next modes.The last mode is maintenance charging. When the battery is fully charged, the charger will turn off the charging indicator light and the fan, and turn on the "Charging - Maintenance" light.At this point, the battery is ready for use, it can be installed in the vehicle. If the battery needs to be stored, the charger will then operate in the support mode, keeping the battery at maximum charge past the storage period. The rectifiers have a number of protections such as: - anti-short-circuit, - against reverse connection of terminals, - against overheating, - against overcharging, - against charging damaged or completely discharged batteries.Protections used in the rectifier allow you to charge the battery without removing it from the vehicle and even perform engine starting while the battery is being charged (providing a slight boost to the start). AGRI 25 -12/24 is a battery charger that meets the requirements of European standards for safety and electromagnetic compatibility. Its manufacturing process conforms to the ISO 9001 Quality System standard.Charging current : 5-15ABattery voltage 12/24VPrinciple of operation of MAGNUM series inverter chargers:The rectifiers charge the battery to a threshold voltage of about 16V (safe for the battery and car system ) , and then switch to a second voltage level of 14V (blue light on), recharges the battery and at the same time can keep it fully charged for a long time.If the battery has already reached 16V after charging for a while and causes the charger to go into the 14V charging/holding state, it means that the battery is fully charged or damaged ( sulfated , bad electrolyte density , mechanical damage to the plates ).The correctness of the charger's charging can be checked on your own using a voltmeter connected to the battery terminals while charging.Rectifiers a number of safety features such as:short-circuit protection, reverse terminal connection protection,overheating protection, overcharging protection, protectionagainst charging damaged or completely discharged batteries. EQUIPMENT:rectifieroperation manualoriginal boxThe Agri 25 inverter rectifier, is designed to charge 12V-24V batteries with a capacity of 50 to 300 Ah, lead-acid batteries of open or closed type (e.g. WET batteries - with electrolyte in the form of liquid, GEL - with electrolyte in the form of gel are now the most popular batteries, and AGM - with electrolyte-absorbing mat.)It has 3 stages of charging: 1 charging with direct current, 2 charging with constant voltage at a decrease in amperage, 3 maintenance (maintenance) charging. After the battery is fully charged, the charger turns off the charging indicator light and the cooling fan. At this point, the battery is ready for use and can be installed in the vehicle.However, if you need to store the battery, you can not unplug it and turn off the charger. It will then operate in backup mode, keeping the battery at maximum charge throughout the storage period.
