| Charge Algorithm | Three stage: Boost CC (Constant current stage) —— Boost CV (Constant voltage stage) —— Float (Constant voltage stage) | ||||||
| Charge Stage Transition Definitions | Boost CC Stage: If A/C input is applied, the charger will run at full currentin CC mode until the charger reaches the boost voltage. | ||||||
| Boost CV Stage: In this stage,the charger will keep the boost voltage in Boost CV mode.The charging current will reduce, until less than 2A, then drop the voltage down to the float voltage. | |||||||
| Float Stage: In float mode,the voltage will stay at the float voltage. If the A/C is reconnected or the battery voltage drops below 12VDC / 24VDC / 48VDC, the charger wil reset the cycle above. | |||||||
