PSU-1228/1250 Alimentation à découpage

Petites alimentations à découpage allant jusqu'à 28/50A.

These power supplies offer in a small case everything the radio amateur needs. 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) or 50A (PSU-1250, 40A continous). This is sufficient for all 100 W 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 PSU-12xx 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. The PSU-1250 has the same design but is somewhat larger.

SPS-1050S Alimentation à decoupage Nouveau

SPS-1050S SPS-1050S

Powerful switching power supply for amplifiers or the entireradio station.

The SPS-1050S is a switching power supply with a max. output current of 55A, manufactured by RM Italy. The continous load is 50A, which makes it particularly suitable for the supply of amplifiers or other large loads.

The SPS-1050S can either be set to a fixed output voltage of 13.5V or to a adjustable voltage of 9 to 15 Volt. This makes it useful for other consumers loads which require a different voltage, or to compensate voltage losses on long cables. Two backlit analog instruments show voltage and current at the same time, for an immediate control of the power supply. Safety measures against too high tempereature or excessive current as well as short circuit help to protect the power supply as well as the load. Weight only approx. 3 kg, size 185 × 113 × 285 mm.
