The Barrett 4022 Power Supply (P/N BC402201) with built-in charger provides regulated 24V power to one Barrett 4050 HF SDR Transceiver and 12V
power to one accessory. The 4022 also has provision for a battery backup
system in case of mains power failure. The battery backup incorporates a
true automatic no-break change over circuit with a battery charging system,
which restricts the output to the maximum 13.8 V of the battery.
The Barrett 4022 is a low noise switch mode power supply which delivers
24 V at 18 amps continuously. It supports a mains input supply that can
vary from 85 V AC to 264 V AC This combined with the ability of the power
supply to operate with a Sealed Lead Acid (SLA) backup battery, makes
the 4022 ideal for use in areas where mains voltages vary dramatically and
occasionally fail altogether. It has a 10 W speaker and an internal fan which
provides airflow to keep the power supply operating at a safe temperature
level even during the most demanding duty cycles.
