PSU-1228 / PSU-1228.DIG / PSU-1228.PP


PSU-1228 Netzteile

In a small enclosure, the power supplies PSU-1228, PSU-1228.DIG and PSU-1228.PP offer everything what a radio amateur needs power-wise. The supplies PSU-12238 and PSU-1228.DIG can be either switched to a fixed 13.8V voltage or to a regulatable voltage from 9 to 15V. The PSU-1228.PP is always wired for a fixed 13.8V voltage.

The maximum power load may peak up to 28A (20A continuous load). This is sufficient for practically all usual 100W transceivers. The built-in ventilator is temperature regulated. At low loads the fan does not move at all, the power supply is completely silent. Only with longer lasting and higher loads the fan begins to turn to cool the compact electronics. To avoid the rarely occuring HF noise effects from the switching circuit a regulator can shift the frequency of the birdies.

The backlit analog meter on the PSU-1228 and PSU-1228.PP can be switched to show either the output voltage or the current load. The model PSU-1228.DIG has a backlit digital readout which shows both, voltage and current. The model PSU-1228.PP is equipped with two sets of power pole connectors.

All controls are located on the front side of the power supply, the input supply connection is on the rear as well as the large DC outlets. The front plate of the supplies have the same size and same design like the well known "SX-..." SWR meters and so fits perfectly into the ham shack.

PSU-1250 Switching Power Supply 50A

PSU-1250

Compact Power Supply 50A

The PSU-1250 offers a lot of power in a small enclosure. The supply is either switched to a fixed 13.8V or to a regulatable output voltage from 9 to 15V. The maximum power load may pek up to 50A, and can stay at 40A continous load. This is absolutely sufficient for larger transceivers (200W) and accessories, or a small power amplifier.

The built-in ventilator is temperature regulated. At low loads the fan does not move at all, the power supply is completely silent. Only with longer lasting and higher loads the fan begins to turn to cool the compact electronics. To avoid the rarely occuring HF noise effects from the switching circuit a regulator can shift the frequency of the birdies.

The backlit analog meter can be switched to show the output voltage or the current. All operating controls are located on the front panel, the connections for AC and DC on the rear side.

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.
