POWERING THE UNIT ON and OFF :
Unit is powered ON by pressing the main power button(1) for 2 seconds.
Unit is powered OFF by holding the main power button(1) down for 4 seconds. When powering OFF the unit a popup screen comes up and shows how long to keep the main power button(1) pressed to power OFF the unit :

OUTPUTS CONTROL

The eSMART TRIO has a total of 8 DC output connectors. The TA4F connector(13), 4 x HRS4 connectors(14) and front panel HRS4 are connected to the “MAIN” output circuit. These output power as soon the eSMART TRIO is powered ON.
Rear HRS4 output connectors AUX1(15) and AUX2(16) can be independently switched ON and OFF using the AUX(2) button on the front panel. A short press on the AUX(2) button brings up a popup screen. While the popup screen is displayed a short press on the MAIN(1) or AUX(2) buttons respectively activates outputs AUX1(15) and AUX2(16). A long press on the MAIN(1) or AUX(2) buttons respectively deactivates outputs AUX1(15) and AUX2(16).

• Status of AUX1(15) and AUX2(16) outputs is saved and restored after power cycling the unit.
• AUX(2) button illuminates if either AUX1 or AUX2 is ON.

BATTERY INFO SCREENS

A short press on the main power button(1) makes the main display cycle thru different battery information screens :

• Battery #1 is the battery connected to power input #1(10)
• Battery #2 is the battery connected to power input #2(11)
• Battery #3 is the battery connected to power input #3(12)

USB OUTPUTS :
The eSMART TRIO has 2 USB power outputs located on the front panel of the unit.
The USB type C connector(3) is Power Delivery capable and can output up to 45W of power in 5 different schemes :

• 5V @ 3A
• 9V @ 3A
• 12V @ 3A
• 15V @ 3A
• 20V @ 2.2A

The power delivery scheme is negotiated automatically between the eSMART TRIO and device connected to the USB-C port(3).
The USB type A connector(5) is Quick Charge 3.0 compatible and can output up to 15W of power in 3 different schemes :

• 5V @ 2.4A
• 9V @ 2A
• 12V @ 1.5A

QC 3.0 power is negotiated automatically between the eSMART TRIO and device connected to the USB-A port(5).

A red LED(15) shows the power status of the USB internal sub-circuitry.

TA4F POWER + smBUS AGGREGATED OUTPUT :
The TA4F output connector(3) outputs power and aggregated smBUS information from all smart batteries connected to the system. This output delivers up to 5A of current and can be used to power an smBUS capable device (such as Sound Devices™ mixers/recorders) or to extend output capabilities via another smart battery distributor such as the eSMART BG-DU.

ACTIVE OUTPUT SHORT CIRCUIT/OVER CURRENT DETECTION :

• The eSMART TRIO has a unique active short circuit/over current monitoring system which helps the user troubleshooting faulty equipment and/or cables.
• In the event of a short circuit (or overcurrent condition) on any of the eSMART TRIO’s outputs the distributor will shut down all outputs to prevent catastrophic failure. A red popup screen will inform the user that a short circuit has been detected and that cables/devices should be checked. The eSMART TRIO will automatically try to restore power within 40 seconds. If the short circuit condition has been removed power will be restored. If not the eSMART TRIO will keep all outputs off and will retry restoring power every 40 seconds.
• In most cases short circuits happen in bad or poorly assembled power cables : a solder connection looses up and shorts battery power to ground. Removing the faulty cable will solve the issue. More rarely an overcurrent can be caused by a faulty device connected to the TRIO. In that case disconnecting the bad device will clear the fault.

SPECIAL NOTES

• All Hirose™ compatible DC output connectors are limited to an output current of 2.5A.

• The eSMART TRIO automatically switches from a configuration to another when plugging/unplugging battery or DC power sources.

• Hot swapping is fully supported and any power source (battery or external DC) can be added or removed without power loss as long as at least one valid power source is always connected to the eSMART TRIO.

• The eSMART TRIO is compatible only with smart batteries and couplers such as the eSMART Li-48neo, Li-96neo, Li-49Wh, Li-98Wh, LiFe-256Wh, LiFe-576Wh, BC1150, BH2, etc…
  It is also compatible with 2054 style smart batteries from third party vendors.

• Even though the eSMART TRIO is capable of delivering up to 11.5A of current it is recommended to limit current consumption to 8A when using 2054 style batteries as these are often limited to 8A. Small batteries like the eSMART Li-49Wh are limited to 4A. So please check max current output of your batteries when configuring your system.
  For optimal performance we recommend using 2 x Li-96neo batteries as these are limited to 11.75A which exceeds the current capability of the eSMART TRIO.

WARNINGS

• Do not short circuit the output(s) of the eSMART TRIO.
• Do not expose the eSMART TRIO to temperatures above 120 deg. F (50 deg. C).
• Do not apply reverse polarity current to the power inputs of the eSMART TRIO.
• Do not draw more than 11.5A total from the eSMART TRIO.
• Do not use the eSMART TRIO in a wet environment.
• Do not power the eSMART TRIO using an AC/DC adapter during an electrical storm.
