A stabilized power supply device with a switching method that adopts a backup current enhancement model when the power is OFF, with a maximum output of 22A.
● The DT-921 (DT921) is a MAX 22A DC/DC converter manufactured by Alinco. ● It adopts a switching method and, despite its compact size, has a continuous output of 20A and a maximum intermittent output of 22A. ● This model is designed to support car navigation systems and radios that require high current during shutdown processing when the power is off. ● The automatic power on/off function, which detects the ACC position, works in conjunction with the backup terminal, allowing for 6A output when the power is off (compared to 1A for the DT-920) and 15A when the power is on. ● The front panel is equipped with a 10A cigarette socket in addition to the main military terminal, and two USB-type connectors that can be used for charging smartphones and other devices, providing a total of 2A. ● The protection circuit includes a thermal sensing fan, automatic output cutoff at high temperatures, overvoltage output protection using a relay, automatic current limiting for overcurrent with a characteristic curve, and automatic shutdown in case of a short circuit, ensuring comprehensive safety. ● It is a higher model than the Alinco DC/DC converter DT-920. ● JAN code: 4969182320169
