Power supply Barrett 2022 is a stabilized DC power source with an output voltage of 13.8 V and a load current up to 21 A, operating from AC voltages from 88 to 264 without switches and transceivers designed for RF power (HF) range 2000 series and accessories. This type of power sources can be referred to the first view.
Barrett 2022 has connectors for the connection of one transceiver 2000 series and one 2000 series of accessories, such as a modem.

Barrett 2022 has power backup battery system that includes a charge circuit with automatic failover to a backup power supply in case of refusal or failure of the main (main) power supply - power. This eliminates the need to restart the modem and re-start their initialization during main power failure. Charge the backup power source occurs during the presence of the main power supply with a maximum current of 3 A. When the backup battery is fully charged in continuous charge mode switches to pulse with the reduced value of the charging current to prevent overcharging.

Barrett 2022 includes a speaker 2000 series transceiver for using it in the configuration of a base station. The loudspeaker is automatically connected to the transceiver through the power source connector. The power supply has a built-in fan for continuous operation in data transfer mode.
