Powerwerx SS-30DV
$$ยทยทยท
| Frequency | n/a (14.1 VDC switching power supply) |
| Bands | n/a (station power supply) |
| Power | A 14.1 V DC switching bench supply. It delivers 25 amps continuous and 30 amps surge (up to 5 minutes); any single output can draw up to 30 A and the total is limited to 30 A. |
| Modes | DC power supply (switching, 14.1 V fixed) |
| Weight | 1.36 kg (3 lb) |
| dc output front | Two sets of Anderson Powerpole connectors on the front (RACES/ARES orientation) |
| dc output rear | 1/4-inch binding posts on the rear (also accept banana plugs, ring terminals or bare wire) |
| ac in | 100-120 / 200-240 VAC switchable (rear 115/230 select switch; ships set to 230 V), 50/60 Hz, internal 6.3 A fuse |
| power req | Universal AC input, 100-120 or 200-240 VAC (set the rear 115/230 switch to your mains; it ships set to 230 V). Output a fixed 14.1 V DC. |
A compact, light, affordable 25-amp (30-amp surge) switching supply that easily powers a 100-watt HF radio, with two front Anderson Powerpole outlets and rear binding posts. It is a fraction of the weight of a comparable linear supply, runs cool with a quiet, thermostatically-controlled fan, has a universal AC input, and carries a three-year warranty. Most users report it is RF-quiet.
Output is a fixed 14.1 volts (slightly above the usual 13.8) and there are no meters on this model. It ships set to 230 V, so US users must flip the rear voltage switch before first use. Being a switching supply, a minority of users report RFI on some bands, so it is worth checking on a sensitive HF receiver.
The Powerwerx SS-30DV is a popular compact switching power supply that delivers a fixed 14.1 volts at 25 amps continuous (30 surge), enough for a 100-watt HF station, with front Powerpole outlets and rear binding posts in a small, light package. It suits anyone who wants an affordable, portable alternative to a heavy linear supply and is mostly RF-quiet; those who need adjustable voltage or built-in meters look at the metered SPS-30DM, and the RF-sensitive may prefer a linear supply. Remember to set it to 115 V.
The Powerwerx SS-30DV is a compact switching power supply for a 12-volt station. It turns household AC into a regulated DC output to run a radio. It is made by Powerwerx, not Elecraft; Elecraft and other radio sellers simply offer it as a companion supply (some buyers receive it bundled with a K4). It supplies 25 amps continuously and 30 amps on surge, which comfortably powers a 100-watt HF transceiver.
Its appeal over a traditional linear supply is size and weight: it is about 6 by 5 by 2.5 inches and only three pounds, where a comparable linear supply can weigh ten times as much. It outputs a fixed 14.1 volts (slightly above the usual 13.8, but within tolerance for typical radios), with low ripple and noise, thermal and over-current protection, and a fan that only spins up above 70 C so it is quiet at normal loads. Most operators report it is RF-quiet on the HF bands, although a minority have reported RFI spikes on some units, so it is worth listening on a sensitive receiver.
For connections it has two sets of Anderson Powerpole outlets on the front, arranged to the RACES/ARES standard, plus 1/4-inch binding posts on the rear that also take banana plugs or ring terminals. One important setup note: it has a universal AC input but ships set to 230 volts, so US users must move the recessed rear switch to 115 volts before first use. It carries a three-year warranty.
It is the light, switching alternative to a heavy linear supply such as the Astron RS-35M, and it pairs naturally with a distribution panel like the West Mountain RIGrunner 4005 to feed a whole station.
