The Astron RS12M delivers reliable 13.8 V DC power with a peak current capability of 12 amps, and features front‑panel analog meters so you can monitor both voltage and current draw at a glance. Built as a solid‑state, electronically regulated linear supply, it features fold‑back current limiting, crowbar over‑voltage protection, and ultra‑low ripple (less than 5 mV peak‑to‑peak full‑load/low‑line) — ensuring clean, stable power for your amateur device, base station, or communications gear. The meter switch allows you to toggle between volts and amps, giving you real‑time insight into what your gear is drawing. The RS12M is designed for heavy‑duty use: it's rated for continuous duty at about 9 amps and intermittent peaks up to 12 amps. Its adjustable voltage (internally adjustable from about 11‑15 VDC) makes it suitable for a wide variety of device installations. Key Use‑Cases & Benefits: Ideal for powering amateur HF/VHF/UHF transceivers, repeaters, or mobile gear in a fixed station environment. The built‑in volt/amp meter gives the user “what's going on right now” feedback — valuable for troubleshooting or monitoring load. Linear, regulated design means extremely low noise and ripple — beneficial for sensitive device setups or digital modes. Manual voltage adjustability allows compensation for cable drop or battery‑like setups. Heavy‑duty build ensures it's not a disposable supply: designed for serious use.
