SEC — switching power supply 13.8/27.6 V, 10–35 A
Country: Netherlands · Model: SEC
SEC switching power supplies deliver 13.8 or 27.6 V DC at 10–35 A from 115–230 V AC, 50–60 Hz mains. Output ripple is < 120–150 mV, so they feed radio stations, communication systems, test equipment and on-board electronics on the bench.

Description
The units come in bench and stationary versions. Output voltage holds within ±1%, so gear built for a vehicle system sees the same voltage it would get from a charged battery. The version for 24 V systems is sold as the SEC-2412G. Depending on the model, cooling is by convection or by a fan, and fan-cooled units need a clear air path. Protection covers short circuit, overload, reverse polarity and overtemperature, so a wrong terminal connection does not kill the supply. The 115–230 V input suits European mains as well as equipment that came from 115 V countries.
How to choose
Size the current by the peak draw of the load, which for a radio means transmit current, not receive. The SEC range covers 10–35 A, and the 13.8 or 27.6 V output follows the supply voltage of the equipment. If the load must stay on through a mains failure, the SEC-1225G-BBM at 25 A with a built-in backup battery module fits better. For rack-mounted telecom nodes needing 100 A with N+1 redundancy there is the 1U SEC-HCP system.
