PSU-1228
Small, switched power supply up to 28A with temperature controlled fan.
The PSU-1228 offers in a small case everything the radio amateur needs. The power supply is either switched to fixed 13.8V, or to a variable output voltage between 9 and 15V. The maximum current may be up to 28 amp, or 20 amp continous load. 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-1228 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 PSU-1228 offers a control which shifts the frequency of the birdies, if required. 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.
