General Description
|
MPEP is a man portable energy pack that is designed to provide power to man portable equipment such as uggedized field computers, displays, night vision system, laser designator and portable PDU's, MP3(For recorded mission instructions).
It consists of Li-Ion type of batteries such as 2590 Ultralife battery, peripheral electronics and firmware. It can be complementary to PCDU series, or stand alone.
It has the capabilities of power management:
- Provides PCDU voltage to equipment and charge MPEP battery while connected to vehicle.
- Provides battery voltage when disconnected from vehicle.
- Selects charging current per vehicle source.
- Provides feedback on charge status for indication.
- Provides two SMBus for:Charging parameters (Voltage, Current and duration)
Communication with portable equipment.
- Push button for temporary battery indication (Colored LED).
- Other supply voltages are optional.
