Imperium IMP002 AC-DC Charger 20A Lithium Battery Charger

Safety

  1. Check the battery’s technical specification very carefully before charging, to make sure that it matches the IMP002 Imperium 20A AC-DC charger’s technical data.
  2. Make sure the charger output is connected securely to the batteries terminal on the correct polarity.
  3. Input/output connectors must be connected firmly during charging.
  4. Reverse polarity connections or short circuits are prohibited during charging, as they will cause damage to both the battery and charger.
  5. If the charger or battery are found to be abnormal or damaged during charge, immediately unplug the input and output cables.
  6. If you use different input wires from the ones supplied then you must make sure that these cables can withstand the maximum input current of the charger, and also that the charger’s input voltage is within its working scope.
  7. If you need to extend the output connection cable, you must make sure that the cable can withstand the maximum output current of the charger and also that the voltage-drop between the charger and the connection wire of the battery is less than 1% of the battery voltage. Otherwise, it may have an adverse affect on the charging process.
  8. DANGER – inside the charger there are high voltage components. If there is a defect you must contact either a qualified electrician, or Purple Line directly. Do not tamper with the casing of the product and do not attempt repairs to the internal components if unqualified to do so.
  9. Never use the charger during a lightning storm.
  10. Ensure that charger does not get wet.
  11. Never use the charger near a heat source or in direct sunlight.
  12. Never use the charger in or near flammable gas.
  13. Ensure the compartment it is mounted in is ventilated and free from dust ingress.
  14. Never place a wire, rod or other metal object into the vents or other openings of the charger body.
  15. Never cover the air vent, and always leave 10cm space for it – at least.
  16. Never shake, bump or drop the charger.

Instructions for Use

  1. Turn off the power switch.
  2. Connect the batteries to the output socket with the output wires supplied -positive to positive, negative to negative.
  3. Plug the input wires in correctly and connect to the input power source.
  4. Turn on the power switch; the LED will flash blue meaning that the battery is being charged.
  5. When the LED turns green this means that the battery is fully charged.
  6. At this stage you can switch off the charger, disconnect he input cable and disconnect the output wires. Or, you can leave it plugged in and attached, so that it can maintain the battery charge.

Product Features

  1. High efficiency, small size, light weight: The IMP002 Imperium charger control circuit uses advanced LLC half-bridge resonant soft-switching power supply control technology. The casing is a robust structure and has a positive thermal design which makes the charger efficient, small and light weight with easy installation.
  2. Multi power supply options and MCU-controlled charging technology: pre-charge mode, repair mode and prolong life mode function for long-term unused batteries.
  3. High reliability: The IMP002 charger is made of high quality industrial level components. Advanced circuit design and strict production process, according to ISO9001:2008 quality management system, make the charger robust, reliable and long lasting.
  4. The IMP002 Imperium charger has multiple protection features: over temperature protection, output short-circuit protection, reverse polarity protection and output over-voltage protection, all of which prevent damage from misuse or incorrect operation.
  5. The charger’s case is made of aluminium alloy with surface oxidation treatment. This sleek design is high-grade, has excellent heat dissipation qualities, is very robust and anti-oxidative and is non-fading.

Charging Modes

  1. Pre-charge stage (T1): When the battery voltage is very low the charger cannot withstand large current charging. In this mode the charger will supply a smaller current for charging. This has the functions of activation, repair and battery life extension. When the output voltage reaches a normal level, or at the T1 of the timing period, the charger will switch to the next “fast charge” stage automatically.
  2. Fast charge stage (T2): When the battery is into the main stage of charging, the charger will quickly charge the batteries with a constant flow, at the maximum current which can be delivered to the battery. When the battery voltage gets up to the maximum charge, the charger will switch to the next “float charge” stage automatically.
  3. Float charge stage (T3): As the charger switches to the float charge stage, the charging current will fall off gradually until the current drops to the
    set value or at the T3 of the timing period. At this stage the charger will turn off the output voltage automatically and the battery charging is complete.

Protection Features

  1. Over Temperature Protection: When the charger’s internal temperature reaches it’s protection point, the charger will stop charging automatically and the LED is always on red.
  2. Output Short-circuit Protection: When the charger has a short-circuit, it will cut off the output current and the LED is always on red.
  3. Reverse Polarity Protection: When the battery polarities are incorrectly reverse connected, the charger will cut off the connection and the LED is always on red.
  4. Output Over-Voltage protection: When the charger’s output is over-voltage, it will cut off the output current and the LED is always on red.

LED Indicator
