Salient features of ESI Charger:
For the life of battery

    1. Pre-programmed multi stage charging profile
    2. Initial de-sulphation ensures cell balancing & longer battery life
    3. Charger prevents over-heating & over-charging of battery
    4. Supersedes standard VOLTAGE sensing (for end of charging process)       by TIMER over ride for ill maintained or aging batteries  

Friendly features for the end-user

  • Depth of charge status by multiple LEDs
  • Charging indication with a blinking LED (LED1).
  • CV  mode charging indication
  • End of charge notification by buzzer and steady glowing of charging LED (LED1)
  • Blinking of end- LED (LED5) for handicapped battery
  • Easy replacement of mother board ensures quick on the spot servicing

For the life and protection of the charger

    • Protection against reverse polarity connection of battery
    • Twin fan cooling
    • Thermal shutdown
    • Standard EMI/EMC compliance
    • Protection against over load & short circuit
    • Protection against input over voltage & surge
    • Inrush current limiting by delay and soft start
    • Incorporation of TVS for protection against switching spikes
    • Multi stage charging reduces over- heating of charger
    • Optimized design for Cost and Quality
    • Generous component layout for easy airflow
    • Proper heat-sinking for good thermal stability
    • Magnetics are vacuum impregnated with class-F varnish
