The RF-5910-PS005 Power Supply provides a regulated output voltage to the AN/PRC-117G(V)1(C) and RF-7800M-MP FALCON III Manpack transceivers from an AC input range of 85-265 VAC/47-440 Hz and a DC input range from 10.5 to 34.5 VDC. It is designed to supply power to the Falcon III Manpacks, without performance degradation, through a TX-RX frequency range from 30 MHz to 2 GHz. The unit includes a rechargeable backup battery, with instantaneous switch-over if both the AC and DC inputs fail or are disconnected. The backup battery enables radio operation for a minimum of 15 minutes. Switchover to the backup battery occurs via a zero-wait switching feature that ensures transceiver operation is not disrupted. The RF-5910-PS005 indicates operational status through the use of three indicators. These indicators display AC ON, DC ON, and battery status.
