The power supplies are either switched to fixed 13.8V, or to a variable output voltage between 9 and 15V. The maximum current may be up to 28A (PSU-1228, 20A continous) This is sufficient for all 100W transceivers. The built-in fan is temperature controlled. With little load the fan does not run at all, the PSU-12xx is absolutely quiet. Only with a longer and higher load the fan starts to run to cool the internal electronics. In cases where interferences occur. The back-lit instrument shows (selectable) either Voltage or Current. All controls are conveniently located on the front, the 230VAC and DC connectors are on the rear. The PSU-1228 has the same front panel size and layout as the well known SX- series SWR\/power meters and so fits perfectly into the ham shack.
