Audioroot eSMART BG-DU power distributor with universal fuel gauge
The eSMART BG-DU is a compact and lightweight powering box with 8 protected outputs, 3 locking switches and a full featured fuel gauge.
This product was designed for use in large sound bags or small location carts. The power distributor can be connected to any battery type (SLA, NI-MH or LI-ION) and the fuel gauge provides all the informations required to monitor the battery’s state of charge (voltage, current, power, etc.).
The eSMART BG-DU uses an internal coulomb counter and a calibration routine to measure the battery’s true capacity and display it’s remaining capacity in real time. This power distributor is also fully compatible with our full line of Li-XXwh smart batteries. A stainless steel clip is included and can be mounted on the top or bottom of the unit for easy attachment in a sound bag.
- real time monitoring of the battery’s SOC : remaining capacity (%), run time estimation, battery voltage, power consumption, power and coulomb counter
- 8 switchable outputs using 3 locking switches
- polyswitch 2.5 A resetable fuses on each output
- a blinking LED indicates when the battery capacity falls below 10 %
- compatible with any battery ranging from 6 to 24 V
- stainless steel clip included
- compact and lightweight : 129 g , 85x75x30 in mm
a 4 conductor battery input cable is required for eSMART operation (i.e when connecting eSMART batteries to the BG-DU). This cable is sold separately under reference eHRS4-OUT-4W. The 2 conductor Hirose battery output cable available under reference eHRS4-OUT will not enable battery data communications between the eSMART batteries and the BG-DU.
FOR HAWK WOODS USERS: the wiring of Hawk-Woods products is incompatible with the BG-DU or BG-DU-REG out of box. On these products the internal pins of the Hirose male plugs are tied together 2 by 2 : pins 1 and 2 / pins 3 and 4. When using the BG-DU or BG-DU-REG pins 2 and 3 of the male Hirose plug connected to the unit’s input must be left unconnected as these are used for communication with smart batteries. Hawk-Woods users can solve this issue by rewiring the male Hirose plug (leaving pins 2 and 3 un-connected) or by removing 2 solder jumpers inside the BG-DU or BG-DU-REG.
the BG-DU can handle standard (non smbus) batteries from other manufacturers up to 40 Ah. A special version capable of handling batteries up to 200Ah can be delivered upon request.
