Annunciators for each solid state breaker on the EXP BUS
* Over and undervoltage warning lights
* Ammeter display
* Instrument light dimmer circuit
* Single ribbon cable installation to EXP Bus
The Indicator module is an accessory for the EXP BUS DC LOAD CENTER. This optional accessory provides several enhancements to the basic load center, all mounted in a small panel mount module, 4.6 inches long, and 2 inches wide. The module extends 2 inches in depth, behind the panel. The module provides an annunciator output for each fused output on the LOAD CENTER, which illuminates if the circuit is tripped. It also provides OVER and UNDER VOLTAGE annunciators, an AMP-METER indicator, and a light dimmer circuit for the instrument lights.
CIRCUIT TRIP INDICATORS
The circuit trip indicators show the status of each load center output, and if any output has been overloaded and tripped, the appropriate indicator will illuminate. These high brightness solid state lamps are dimmable. The lamp will remain illuminated until the load is removed (the circuit is switched off). If no circuits are tripped, the indicators will all be dark.
OVER VOLTAGE and UNDER VOLTAGE
The OVER VOLTAGE and UNDER VOLTAGE warning lamps illuminate whenever the bus voltage is below 11.5Volts, or above 16 Volts. (22 to 30V for 28V systems) These bright indicators are also dimmable.
The AMMETER function uses a shunt built into the EXP BUS product. The ammeter indicates current flow into or out of the battery, from -40 to plus 60 amperes.
The Indicator mounts in a 4.25 by 2.0 inch rectangular hole in the panel. A flat black bezel and lens assembly compliments your instrument panel.
