Battery Charger-Analyzer for small battery systems (up to 10A-Hr)

24-400l.jpg (224219 bytes) 

  • The 24-400L is an instrument designed to charge, trickle charge and analyze (discharge) Nickel-Cadmium, Sealed Lead-Acid and other types of rechargeable batteries.
  • With its multiple modes of operation of Constant Current Charge, Constant Current & Float Charge, Constant Current & Peak Stop Charge, Automatic Discharge (analysis) and Full Discharge (deep cycle), the 24-400L can satisfy the requirements of most small (0 to 10 A-hr) rechargeable battery systems.
  • The charger features safety interlocks to protect the operator, the charger and the battery in the event of reversed polarity connection, short circuit, open circuit (no load) and overvoltage conditions.
  • Two large LED digital meters permit the simultaneous monitoring of voltage and current, while six indicator lights inform of the status of the operation.
  • An optional external electronic timer (Timer 24) complements the 24-400L charge and discharge operations in applications requiring a time limit.
