PSU 1228 Switching power supply 28a Max

{ } power power supply 28a max, q {}} the power supplies offer in a small case all the amateur radio needs. The power supplies are to go to 13.8v fixed or from a variable output voltage between 9 and 15V. The maximum current can be up to 28a (PSU - 1228, 20th continuous) or 50a (PSU -1250, 40th continuous). This is enough for all 100W transceivers. The built -in fan is at controlled temperature. 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 to work to cool the internal electronics. In cases where interference occur, the PSU-12XX offers a control that moves the frequency of birds, if necessary. The Back-Lit Shows (selectable) voltage tool. All commands are comfortably positioned on the front, the 230Vac and DC connectors are on the back. The PSU -1228 has the same size as the front panel and well -known graphics SX - SERIES SWR / Power and therefore fits perfectly into the shack ham. The PSU -1250 has the same design, but it is a little bigger. {
