AH Prover

To Monitor Battery Discharge levels in Traction Applications

  1. The SIRIUS AMPERE HOUR PROVER is a diagnostic test instrument designed to check the performance of industrial batteries, chargers and vehicle electrical systems under actual operation. The instrument is easy to install and provides accurate performance measurements in a highly readable form.
  2. The SIRIUS AMPERE HOUR PROVER is designed to work with batteries for 24V and 48V upto 1500Ah battery and displays typical performance parameters like instantaneous voltage, instantaneous current draw, run-time and discharged/charged Ampere-hours in an alphanumeric LCD display.
  3. The instantaneous current is displayed as a signed number: '+' for charging and '-' for discharging.
  4. The Ampere-hour register counts up or down depending on whether the battery is under charging or is working into a load. The Ampere-hour count is also displayed as a signed number – this reading represents the net Ah drawn from/restored, to the battery from the instant the instrument is connected.
  5. The run-time register counts up when current is drawn from the battery, which provides information about actual working hours of the battery in the vehicle.

Buzzer activated at LOW BATT condition.
LOCK OUT relay will activate when either the on-

discharge voltage or the Ah drained from the battery falls below programmable thresholds whichever is earlier. Relay N/O and N/C contacts are brought out for wiring to the lift motor.

Applications

CHECK BATTERY CAPACITY ON USE

Take a fully charged battery, connect the AHP, use the truck till battery is 80 % discharged.
