These power supplies offer in a small case all amateur radio needs. Power supplies are switching to 13.8 V fixed or variable output voltage between 9 and 15V. The maximum current can be up to 28A (PSU-1228, 20A continuous) or 50A (PSU-1250, 40A continuous). This is sufficient for all transceivers 100W. The fan is temperature controlled. With little effort the fan does not work at all, the PSU-12xx is absolutely quiet. Only with a longer and higher load the fan starts running to cool the internal electronics. In cases where you are experiencing interference, the PSU-12xx offers a control that shifts the frequency of birds, if necessary. Back-lit tool shows (selectable) voltage or current. All controls are conveniently located on the front, rear and DC are connectors 230VAC. The PSU-1228 has the same front panel size and graphics well known SX-series SWR/power meters and therefore fits perfectly in the ham shack. The PSU-1250 has the same design, but is a bit larger.
