Intelligent Power Management
The SX-M2D2's intelligent power management is a combination of hardware and
software which optimizes the distribution and use of electrical power.
It includes the following:
•
High efficiency current limited switching power supplies with automatic load
prioritization
•
Automatic battery charger, low-voltage battery pre-conditioning, detection of
faulty cells and thermal monitoring for charging pause in case of overheating
•
Ultra low standby current
•
Removable battery charge state and voltage measurement
•
Under-voltage automatic power-down
•
Smart load shedding, which shuts down unused inputs and outputs
•
Display auto-off

Power Sources
The SX-M2D2 has two external power connectors and an integrated battery.
The battery must be present in the device to ensure that all functions are always
available.
These sources are independent and can be used simultaneously to prevent a power
failure.
When a power source is disconnected (or fails), the SX-M2D2 automatically switches
to an available power source.
This list reflects the SX-M2D2 power sourcing priority:
1. Hirose 4-pin connector
2. USB Power connector
3. Removable Li-ion battery cell
NOTE
USB Power input can drain up to 1.3A
WARNING
The battery must be present in the device to ensure that all functions are
always available.
The SX-M2D2 can be powered by an external source, without a battery
for a few moments when replacing a discharged battery with a charged
one.
