Integrated internal battery 7.4 V, 7800 mA-hr, Lithium-ion
Internal battery operates as a UPS in the event of external power source
failure
Internal battery will charge from external power source when input
voltage is >15 V
Integrated charging circuitry
Power input on Lemo 7-pin 0-shell is optimized for lead acid batteries with
a cut-off threshold of 10.5 V
Power input on the 26-pin D-sub connector is optimized for Trimble
Lithium-ion battery input (P/N 49400) with a cut-off threshold of 9.5 V
Power source supply (Internal/External) is hot-swap capable in the event of
power source removal or cut off
9.5 V to 28 V DC external power input with over-voltage protection
Receiver will automatically turn on when connected to external power
Power consumption 6 W, in rover mode with internal receive radio
8 W in base mode with internal transmit radio
