The Astron "50" series are heavy-duty power supplies capable of supplying 37 amps continuous at 13.8 VDC from 115 VAC line voltage. The output voltage is adjustable from approximately 11-15 VDC. These supplies are protected against overload and short circuits by foldback current limiting.
The RS-50M delivers a nominal 13.8 VDC output, which is internally adjustable between 11 to 15 VDC. It provides 37 Amps continuous current and can handle 50 Amps intermittent surge. The ripple is less than 5 mV peak-to-peak, ensuring stable DC output for sensitive equipment.
The RS-50M does not use a fan; it relies on its heavy-duty heat sink for passive cooling. This design minimizes noise and maintenance while still allowing for stable operation.
The RS-50M measures 6 x 13.75 x 11 inches and weighs 46 lbs. This makes it a robust desktop supply suitable for both home and amateur radio or laboratory use.
