13.8 V desktop power supply

The Astron SS-25 delivers 13.8 VDC from a 120 to 230 VAC source with automatic wide-range input selection. It provides 20 A continuous output and 25 A peak for intermittent communication service loads. Two USB ports supply 5.2 V at 1.5 A each for charging accessories. The unit is sold new and intended for desktop use.

Automatic wide-range input and output limits

The supply accepts nominal 120 to 230 VAC at 50 or 60 Hz without manual switching. Continuous current is limited to 20 A while peak demand may reach 25 A under ICS rating. Output voltage can be adjusted by ± 1 V from the 13.8 V nominal setting. Two Anderson Power Pole ports and rear two-wire terminals handle the DC connections.

20 A continuous versus 25 A peak current

The single specification that decides suitability is the 20 A continuous rating against the 25 A peak allowance. Equipment drawing more than 20 A continuously will exceed the design limit even if peak headroom exists. Buyers needing sustained current above 20 A should select a higher-rated unit.
