What type of power supply should I use?

To use the WMA-02 high voltage amplifier, you should use a 24V DC power supply with a continuous output current capability larger than 200mA. If the power supply has an adjustable current limit, it should be set at 200mA or higher as well. Falco Systems offers a suitable 24V power supply; for more details, please visit

How much power does a power supply provide?

How Much Power? Power supplies are often rated by their continuous and intermittent/peak (ICS) current capacities. The figure you want to look at is the continuous rating—the amount of current the power supply can provide. For example, the Samlex SEC-1235P-M switching power supply is rated 30A continuous output, 36A peak.

What is a good power supply for a 25 AMP Radio?

Some good examples of switching supplies in the 25-30 amp range are the Samlex SEC-1235, Alinco DM-430T, and the Astron SS-30M. Astron has a good line of linear (transformer) power supplies that start at a slightly higher price point. If you have one radio, hookup is fairly simple.

What are the different types of power supplies?

Power supplies come in a variety of configurations, from simple to full-featured. Basic models just change 125VAC to 13VDC. Typical add-on features include volt/amp meters, multiple power outputs, noise offset controls to minimize RFI, variable voltage output controls, and over-temperature protection.

Are switching power supplies better than AC power supplies?

These power supplies are often large, heavy, and more expensive than switching power supplies discussed below. Many old-timers believe they are better because they’re less likely to generate RF noise. With switching power supplies, the AC line voltage is converted directly to DC and filtered.

How do I choose a DC power supply?

DC output options available on power supplies can include Anderson Powerpoles, binding posts, set screw terminals, and lighter plugs, or combinations of these. Choose the options most useful to you. Don’t worry about buying a power supply with a little extra current capacity. Your equipment will only draw the current it needs—no more, no less.
