Used as battery charge / discharge meter, CURTIS 906 state-of-charge gauges are widely applied by golf cart and electric forklift makers. CURTIS 906 meter is a simple and effective BDI (battery discharge indicator). Typical model: 906T36HNDAO, 36V with CURTIS logo.

Overview

Model 906 is an inexpensive, one piece, easy to install battery fuel gauge. It is completely solid state and provides a reliable, accurate, and easy to read display of battery state-of-charge. Model 906 is available in six panel mount packages and a printed circuit board mounted module for custom dash panel applications.

  • The Output Signal option causes the voltage on pin 3 to drop from 5 to 0 volts at 80% discharge. It can be used to signal another component or to allow for the disabling of a specified vehicle function, insuring against abusive deep discharge conditions.

Specifications

  • Manufacturer: CURTIS

  • Model: 906

  • Voltage Options (Volts):

    • 36V: 906T36HNDAO

  • Operating voltage: +/–25% of nominal voltage

Features include:

  • All principal circuits are integrated in a single chip for long-life reliability.

  • A 10-bar LED displays the state-of-charge successively, bar by bar, from full to empty.

  • At 70% depth of discharge, a flashing LED signals an “energy reserve” alert.

  • At 80%, alternately flashing LEDs provides an “empty” status warning.

  • Model 906 is compact and easily installed in panel cutouts as small as 36.8 X 24.1 mm, with as little as 35 mm behind panel clearance needed, see dimensions of various case styles.

  • Recognizes improperly charged battery.

  • Keyswitch activated LED display (state-of-charge is monitored as long as 906 is connected to battery).

  • Memory allows gauge to recall state-of-charge whenever battery is disconnected.

  • Three possible reset methods:

    • Open Circuit Reset (OCR): Upon reconnection of a battery the gauge will reset if it measures 2.09 volts/ cell or higher (example “B” profile) (for units with memory option).

    • High Voltage Reset (HVR): Gauge must measure >2.35 volts per cell for 6 continuous minutes during charging (example “B” profile).

    • Charge Tracking Reset (CTR): Display tracks charge level during opportunity charging (requires gauge to be connected to battery when charging).
