Description The Mean Well PB-300P-12 is 12V 20A (12.5A continuous) intelligent 3 stage battery charger. Designed to charge lead acid (flooded, Gel, AGM) and Li-ion (lithium iron & lithium manganese) type batteries. Note: the charging curve is designed for lead-acid batteries, speak to us if you wish to operate with other battery chemistries. Recommended battery size: 60 ~ 200Ah Features: Passive PFC Adjustable charging voltage Protections: Reverse polarity Short circuit Over voltage Over temperature LED (2 colour) loading indicator Cooling by free air convection High reliability – 3 year warranty 3 Stage Charging Program Stage 1 – Bulk Charge This is where the battery typically receives the initial 80% of its charge. The charger is operating in constant current mode, where the maximum current is delivered and the battery voltage rises to 2.4V per cell. This stage finishes when the battery’s voltage reaches it’s peak. Stage 2 – Absorption This is where the battery typically receives the remaining 20% of its charge. The charger is operating in constant voltage mode, where the maximum voltage of 2.4V per cell is delivered and the current decreases. Stage 3 – Float This is where the voltage lowers to the maintenance level 2.3V per cell to maintain charge.
