Tim Gelvin K3TEG –
This would be a great addition to my shack, however, we need a power supply that can switch automatically to 12v battery when the AC power goes off due to extreme weather. And when in steady state, this power supply would be giving the battery a trickle charge to keep the battery fully charged. It must work with all types of batteries including the LiFEPo4 batteries.
The Dude –
I’ve been using this RPS-50PRO for about 3 weeks. It’s worked flawlessly so far, though I haven’t pushed it hard at all. The heaviest I’ve used it is transmitting ~50 W on a VHF radio for a short time. That was a 9 amp draw. I have a 100 W capable Ham base station which would draw about 23 A. A supply rated for 25 continuous should handle things, but extra capacity is never a bad thing.
I got this to replace a TekPower TP30SWII. The TekPower is a 25 amp (30 max & 25 continuous) supply which honestly covered my needs for power, but it has a needle meter which can show you voltage and current, but not both at once. One has to switch between which measurement to display. The other thing is the ammeter side was flaky and not accurate. Bottom line I want to see both voltage and current at once at a glance, and if I had to pick one to leave it on most of the time it would be current. So, time for an upgrade. TekPower came out with a newer model (the TP30SWV) which has a digital display that shows voltage and current simultaneously but otherwise is the same. This would undoubtedly meet my requirements as well. The TP30SWV appears to be the same unit as BTech’s RPS-30PRO. Of those two I would choose the BTech RPS-30PRO because of BTech’s U.S. support etc. Also, the RPS-30PRO has white contrast on the adjustment knobs for voltage and noise offset. That’s a nearly insignificant detail, but a nice touch just the same.
But, since I was upgrading… I saw this newer BTech RPS-50PRO. It also has a dual digital display which has a very nice high contrast uniform backlight. Better yet, it supports twice the sustained current draw as the others mentioned here. I don’t technically need that much, but extra capacity can’t hurt and probably will offer better reliability for the long haul. Other benefits of the RPS-50PRO is that it offers what I consider more flexible front panel power connectors. Like the other units mentioned, the RPS-50PRO has binding posts on the rear which is pretty standard and also a 10 A cigarette lighter socket on the front. It does not have a spring terminals like on the other units but, instead it provides 2x power-pole connectors and 2x USB C connectors. The USB C connectors are 5V of course and 2 A capable. The power-poles are what helped sell me. The USB ports would have also helped sell me except they are unfortunately a bit hamstrung. See below for info on that in the criticisms section.
Now I’ll mention what I don’t really like about this unit. The list is pretty short and not show stopping, but I think it’s deserved criticism. Unless this unit lets me down in the future, really at this point my only real gripe with it is the USB ports. They are USB C. That would be on the right track for the future IF they were PD (power delivery capable), which they are not. Having a box like this with all that DC power capability and not providing the PD circuitry is a crying shame. But, if you are going to skip the PD capability, it would be better to provide USB A ports instead of C. Why you ask? Because if you have a USB C port which is dumb, meaning lacking PD circuitry, then in many / most cases anything you plug into it will default to limiting it’s current draw draw to 0.5 A lowest common denominator USB spec power draw. 0.5 A is only 25% of the measly 2 A the port could otherwise support. That’s only enough power to keep a lot of modern smartphones just treading water with no appreciable recharging possible. If the ports were of the A type, there is a better chance that your device would be able to pull the rated 2 A out of the port. It’s not guaranteed as it depends on a number of variables (beyond the scope of this review), but the odds are at least much better. But with this: dumb C type ports, you are virtually guaranteed to be limited to just a sip of power. If you are going to have USB C ports, then they should have circuitry which can negotiate the power levels appropriately. I don’t know what the margins on these RPS-50PROs are, but PD smarts could probably be added without cutting into it too deeply. If not, an appropriately modest price increase to accommodate PD smarts would be well worth it IMHO. Otherwise, just put type A ports on please.
