Auber EZboil DSPR 400 Controller

[Salt Must Flow]

List of major components:
Auber EZboil DSPR 400
Aluminum enclosure
Power on/off switch
Flashing Buzzer, 110 or 240V AC. 22 mm
12V Green Indicator Light
RTD Sensor PT100
RTD Sensor Panel Mount
RTD Sensor Extension Wire - soldered to the RTD sensor panel mount and connected to the EZboil DSPR 400
40A SSR
Aluminum heatsink
Male Twist Lock Plug 30A
Female Twist Lock Plug 30A

I installed the fan on the top of the enclosure to blow air down directly onto the heatsink & SSR. That's a green indicator light, red flashing alarm/buzzer and an alarm kill switch. The kill switch is handy so you can shut the alarm off immediately then you can turn the alarm setting off withing the EZboil controller.

Thank you for taking the time to write this up!

No problem. I think I even have a template I drew in CAD for the cutouts. I'll try to figure out a way to convert the drawing to PDF or a .jpg or something.

Nice rig! Mine is similar. Love the DSPR400.

I'm thinking, for my hot plate and air still (both 120v) I could take the SSR hot output and a neutral line and run them to an outlet. Haven't had the chance to draw it up or try it yet, but I can't see why the SSR wouldn't work in a 120v circuit.

The only thing I would be wary of is any internal safety components that would make the SSR controlled outlet moot.
They may be set to turn off or operate differently if exposed to low voltage.

Now that you mention that, I looked up the Auber SSR and it rates the operating voltage as 24-480, so I don't think it'd be an issue.

I have an SSVR for the 120v systems and it works fine, but I like the digital nature of the DSPR.

I meant with your hot plate and air still. They may have safety features that shut the items off when voltage isn't up at 110v

You certainly use use the same Auber conroller using an SSR and make it run with a 120V circuit. If I can figure out how to send you an image in a private message I'll send you a wiring diagram. All of the EZboil models can, but the DSPR 400 model is the most feature rich version. As pointed out by bcook608, if the air still or hot plate has built in controls then it might not work quite right for those heat sources. I had to bypass similar controls with a 120V hotplate in order to use my controllers otherwise they would interfere with the controller's operation/control.

Ah, yeah. Both the air still (the way I run it at least) and the hot plate I have if set on high run straight, brainless, 100% on heating coils and work fine with an SSVR so I don't think the switch to an SSR would be an issue.

But a good point for others who may be running different units. Especially anything that's got any circuitry in the heater.

Thanks bcook.

Oh, I think I know how. Take the hot going through the SSR and run it to the hot side of a standard 120v outlet, take the neutral from your 4 wire input and run it to the neutral side, and don't forget the ground. Then just plug in. I can probably have both the 120v and the 240v outlets 'live' as long as I only use one at a time. Now I just need to find the time to tinker with it.

I agree on the 400 having all the features and for only something like $10 more. A versatile little unit.

Thanks.

Sounds about right. Basically you'd just treat it like any other controller except you'll be wiring up an outlet instead of an element. You end up with the same 3 wires going to it. I've actually seen more than a few people do it this way on the forum to make swapping the controller from one rig to the other quick and easy. They just wire a pigtail onto the element and wire the controller up with an outlet like you're referring to.

I can't remember exactly where I've seen it as I've been doing TONS of reading in the "Related Electrical Accessories" board, but they're there for the finding if you're looking for wiring diagrams or inspiration.
