Csd-sa1e0-1

What is a CSD-SA1E0-1 you ask?

It's the gadget on the lower right..

http://cgproducts.johnsoncontrols.co...q=CSD-SA1E0-1*

Wow, that's some URL..

I was thinking of making my own 230vac circuit breaker..
Just add a big honkin SSR and some controls..?.

Or, maybe just an over-current alarm?

Do I understand their description correctly? It appears to be a device made to monitor the amount of power a hardwired item is consuming, such as a stove or an HVAC unit. I like the way it installs around the wire it is monitoring.

Seems like a great way to monitor the performance of an item that was not reasonable to monitor before.

Xringer · 01-06-11, 08:39 AM

It's basically an AC current level detector that can be used, to control a device,
like a compressor motor, because it can be set to trigger when Amps exceed your setpoint.
(It's NO, and the contacts close when the current is => than the setpoint).

They also use these to insure motors (or other loads) keep drawing their normal power.
If a motor draws 10A normally, and the setpoint is 8A, the contacts stay closed all the time.
But, if the belt falls off, (or other problems) cause the motor to run at <8A, the contact will open.
Lighting up the Belt-Off LED or shutting down the power supply..

I got this brand new off Ebay for $1.26. But the bad news is, $15.99 shipping.
(The stamp shows he paid $1.73 to ship it to me)..

That all adds up to 89.09 bucks Canadian..

I'm going to figure out a way to use this thing.. Just need to think about it for a day or two..

OK, it makes even more sense now that you explained it.

As for the Ebay pricing, I believe that many sellers make the sales price way lower than it should be and the shipping price way higher than it should be in order to reduce the amount of money they have to pay Ebay as a commission.

I was wrong about the picture.. Those are the non-adjustable versions.
Mine has a trim-pot and two indicator LEDs.

Anyways, I was thinking of building a sensitive 230vac Circuit-Breaker for my Sanyo.
It would kick-out and remove power from the Sanyo if it went over a 10A set-point. (2500w).
And then, it would wait for 5 or 10 minutes and restore the power.
The Sanyo will come back up, and go into shut-off mode (deep standby).
The only thing using juice will be the compressor heater.

BUT, the remote control unit, sends updated temperature information to the Sanyo every 5 minutes, (it's on battery),

The IR data burst will also turn the Sanyo back on and it will start the compressor again after it's standard 5 minute time delay.

Seems like a good DIY project.. Just need two 220v SSRs, a 555 timer and a small power DC supply.

Xringer · 02-08-11, 12:03 PM

Another app would be to sense the Sanyo was using over 400w and trigger an SSR
to connect a GTI to the AC line.

By using DC from the PV as the trigger PS source, the GTI would be off-line, when:
Sun isn't out, AND when the Sanyo isn't running over 400w.

By using under 400w of PV, no power would ever be put on the grid..
Still, I wonder if that would be legal..

(The array on the left is 400w).

This CSD-SA1E0-1 gismo is a life saver!

My efergy power monitor failed yesterday. I think the receiver has died.
The transmitter and current probe is still working.

Anyways, I have to have a way to monitor the Sanyo's power use!
I hooked* the CSD-SA1E0-1 to the 240 AC line going to the Sanyo
and used the output lines to control a beeper connected to a 5VDC PS.
(* Used 4 loops around the core, it's a non-contact pickup).

The Radio shack beeper was too weak, so I recycled a horn from an old smoke detector.
(After carefully removing the radioactive canister).

If the Sanyo starts using over 2300 watts tonight, that horn is going wake up the whole neighbor hood..
I even had to put some gorilla tape over it's output.. It was too loud!

Edit 3/15/2011:
It was really damp and frosty last night and the Sanyo defrosted three times.
The alarm went off at 1:30, 3:30 & 7:45 AM..
It was doing 2.5 to 2.6kw when I reset it. (Power off, power on).
Woke me up too once too many times!
I'm going to convert this alarm into an automatic programmable load controller..

I found some cheap 230v SSRs (Solid State Relays) on Ebay.
New in Box Solid State Relay SSR 24-480V AC, 25A - eBay )

I'm thinking of using two of these. Putting one on each side of the 230vac feeding the Sanyo.

The SSRs would be normally On, and I would use the CSD-SA1E0-1 over-current signal to turn them off.

At first, I was thinking of using a timer to insure the power was totally
disconnected from the Sanyo for a few seconds.
That would insure the Sanyo would go into a Power Fail Recovery mode,
once timer ran out and the power came back.

But, then I started thinking about skipping the time delay..

1. Over current occurs at 10A.

2. The CSD-SA1E0-1 contacts close, turning off the 5VDC control voltage to the SSRs.

3. The SSRs remain On, until the 60Hz Zero-crossing. Then shut down.

4. No AC current shuts off the CSD-SA1E0-1 and it's 'contacts' open.

5. The 5VDC control voltage is re-applied to the SSRs.

6. At the next Zero-crossing, the SSRs come back on.

7. AC Power is re-applied to the Sanyo.

Depending on the speed of the devices, I guess the AC would be off
1/2 to a full cycle, at a minimum.
The maximum time off could be a few cycles. And it should be possible
to add a tiny time delay, using a small capacitor on the 5VDC control switch.

The goal of a very small time delay, would be to reduce the AC frequency
somewhat, while leaving the voltage alone.

Since Amps are a measure of electrons-per-second, I think, the delay might
reduce the watts being used by the Sanyo..

In other words, it would be a Power Limiter. .

If the CSD-SA1E0-1 was set for 10A, (and the voltage was 250vac),
then it would be impossible for the Sanyo to draw more than 10A.
Thus it's power use would be limited to 2500 watts..

Comments??

Yeapers, I found another current sensor.
VERIS HAWKEYE 705 Solid State Status Sensor 135A 600V - eBay (item 220263071259 end time Apr-15-11 10:19:44 PDT)

Model 705
Max Sensed Amperage: 135A @600VAC
Max Output Switching: 0.2A @ 30VDC (Solid State)
MADE IN THE USA BY
Veris Industries, Inc. in their Wilsonville, Oregon plant.

It seems to have the same specs as the other other one..
These are cool devices, IF you have an app..

Xringer · 04-03-11, 08:48 AM

I tested the new (used) Hawkeye Model 705 current sensor using 120vac.
Put 3 loops though the core and used a space heater for the load.

It's got N.O. contacts until the setpoint is hit. (Just like the 1st one).
But, it seems to have a lot of hysteresis.
That won't matter if it's used as a circuit breaker (as in my Sanyo app),
since the loss of load kills sensor's operating power.
Contact closure only lasts milliseconds after the trip.

It might be more sensitive (smoother?) at 230vac..?.

You can still find the Hawkeye 705 for 15-20 USDs.
But, I really like the CSD-SA1E0-1, it seems to be a more precision device. Easy to adjust etc.
