ePOWER Smart Charger - 20Amps / 12V EN31220 e P O W E R Smart Charger - 20 Amps / 12 V Features Multistage Charging: Fully automatic multistage battery charger with the ability to charge 3 separate battery banks. Separate Battery Banks: Isolated charging design where battery bank one is separate from battery bank two and three. Programmable: Battery bank 1 can be programmed with a different charge algorithm over banks 2 and 3. Current Control: User adjustable current output (e. g. Dial the 60amp unit back to run off a 1k V A generator). Smart Charging: The e P O W E R 30 A battery charger will regulate its output based on the loads connected to your battery banks. Wide A C Input Range: Operates on both 110 V / 60 Hz and 240 V / 50 Hz. L E D Display: Easy to useset and select menu along with scrolling charger status. Silent Mode: Disables the cooling fan for total silent operation at night or whenever required. Activation reduces charge output by half and locks out fan for 12 hours. Temperature Sensor: Battery temperature sensor included with 3 meter cable. 2 Year Warranty from an Australian company renowned for customer support Please Download e Power Battery Charger User Manual for more information Please Download e Power Lithium Charging Profile for more information Multistage Charging Process The Enerdrive e P O W E R 20 A Battery Charger is a fully automatic,set and forget charger. It is designed to quickly and accurately recharge your batteries using algorithms that help maximise service life. Multistage smart charging technology enables the charger to be connected to your battery banks permanently. As dictated by battery manufacturers recommendations, batteries require a multistage charge sequence for perfect, fast and accurate charging. Our e P O W E R multistage smart 30 A battery charger delivers four primary charge stages: -Stage 1 Bulk or Boost Charge; The battery is charged at full rated output current of the charger until the battery reaches its final charging voltage, known as its absorption voltage. In this step, around 80% of the battery capacity is recovered as fast as possible. Stage 2 Absorption Charge; With the charger voltage held steady the remaining 20% is replaced allowing the current to drop as the battery approaches its full charge. Stage 3 Float; Finally, in the float stage the charger voltage is lowered and held at a constant and safe predetermined level. This prevents the battery from being overcharged while supporting any additional loads connected to the battery, such as D C lighting and refrigerators. This stage allows for the charger to be used as a D C power supply. Stage 4 Maintenance; This stage is a regular timedreturn to bulk stage. After 7 days of constant operation infloat the Enerdrive e P O W E R Battery Charger will switch the charger from float to bulk to agitate the batteries electrolyte helping to provide an extended service life. All About Lithium The recent advances in high capacity Lithium battery technology have seen the need to develop a battery charger suited to their needs. With most traditionalsmart chargers their suitability to Lithium batteries is limited. Lithium batteries require a constant current / constant voltage charge algorithm and are unique in that almost every amp-hour of charge delivered by the charger is accepted as one amp hour into the battery, hence the need to deliver a constant current as long as possible. The Enerdrive e P O W E R charger can be programmed for Lithium batteries. This setting delivers the full rated output of the charger constantly with the charger switching to power supply mode once the voltage peak is met (indicating a full battery bank). The graph shows the e P O W E R charger algorithm perfectly supporting Lithium battery requirements. The Display Panel The e P O W E R 20 A Battery Charger display gives you all the information you need for the operation of your charger. At a glance, key information such as charger amps, battery voltage and charge state continually alternate on the screen. When in float / power supply mode, the load amps are displayed so you can see exactly what the charger is doing. The display also allows you to program all settings of the charger, as well as activate the silent mode. Silence when you need it By pressing theS E L button for 5 seconds, the e P O W E R Charger enters theSilent mode that prohibits the fan from working. This ensures totally silent and safe operation at night, ideal if the charger is located close to your sleeping quarters. Silent mode limits current output to no more than 50%, and is programmed to remain on for 12 hours before automatically returning to a normalfan-on & full output setting. Battery Temperature Sensor Included standard with all e P O W E R Battery Chargers.
