eSmart ABE Battery Eliminator

The Audioroot eSmart ABE is an active battery eliminator which can be used to power smart battery operated devices with an alternative DC source such as an AC/DC power supply, wall adapter, or even another battery. A smart battery can also be connected to the ABE’s power input connector to allow larger smart batteries to be used to power devices which normally accept only small format batteries such as the Li-48neo or Li-49Wh.

Wiring of the TA4M input connector :

1.     (-)
2.     SMBus data*
3.     SMBus clock*
4.     (+)

*Wiring of pins 2 and 3 is not mandatory

The ABE includes a smart battery emulation circuit to allow display of some information on Audioroot smart current distributors when a simple DC power supply is connected to the ABE (i.e pins 2 and 3 left unconnected). The ABE’s smart battery emulator is compatible with the following devices :

•  eSMART BG-DH MKII
• eSMART BG-DU
• eSMART BG-DU-REG
• eSMART K-ART

The following informations are available when using the devices listed above with the ABE when smart battery emulation is active :

• voltage
• current
• power
• temperature

Ih this configuration (external DC power source and smart battery emulation ON) other values such as cycle count, capacity and runtime are displayed with arbitrary values.

When should I enable the ABE’s internal smart battery emulator?
The switch enabling the ABE’s internal smart battery emulator should be set to ON when using the ABE to power a eSMART BG-DH MKII, BG-DU, BG-DU-REG or K-ART from a DC power source.

The ABE’s internal smart battery emulator should be set to OFF when a SMBus compatible battery is connected to the ABE’s TA4M input connector using a 4 conductor cable (power + clock/data signals).
