Phoenix Battery Charger, 12 volt 30 amp | Victron Energy PCH012030001

Adaptive 4-stage charge characteristic: bulk – absorption – float – storageThe Phoenix Charger features a microprocessor controlled ‘adaptive’ battery management system that can be preset to suit different types of batteriesThe ‘adaptive’ feature will automatically optimise the process relative to the way the battery is being usedThe right amount of charge: variable absorption timeWhen only shallow discharges occur (a yacht connected to shore power for example) the absorption time is kept short in order to prevent overcharging of the batteryAfter a deep discharge the absorption time is automatically increased to make sure that the battery is completely rechargedPreventing damage due to excessive gassing: the BatterySafe mode (see fig. 2 below)If, in order to quickly charge a battery, a high charge current in combination with a high absorption voltage has been chosen, the Phoenix Charger will prevent damage due to excessive gassing by automatically limiting the rate of voltage increase once the gassing voltage has been reached (see the charge curve between 14,4 V and 15,0 V in fig. 2 below)Less maintenance and aging when the battery is not in use: the Storage mode (see fig. 1 2 below)The storage mode kicks in whenever the battery has not been subjected to discharge during 24 hoursIn the storage mode float voltage is reduced to 2,2 V/cell (13,2 V for 12 V battery) to minimize gassing and corrosion of the positive platesOnce a week the voltage is raised back to the absorption level to ‘equalize’ the batteryThis feature prevents stratification of the electrolyte and sulphation, a major cause of early battery failureTo increase battery life: temperature compensationEvery Phoenix Charger comes with a battery temperature sensorWhen connected, charge voltage will automatically decrease with increasing battery temperatureThis feature is especially recommended for sealed batteries and/or when important fluctuations of battery temperature are expectedBattery voltage senseIn order to compensate for voltage loss due to cable resistance, Phoenix Chargers are provided with a voltage sense facility so that the battery always receives the correct charge voltageUniversal 90-265 V AC input voltage range and also suitable for DC supply (AC-DC and DC-DC operation)The chargers will accept a 90-400 V DC supply.
