Thanks everyone.
Roberto, your explanation makes a lot of sense and I assume Jebao is going to be controlling the signal when they add "the function to the controller which can adjust the speed" and that's what they adjust for the night mode, which runs at 1/3rd power.

Although they do offer a variable voltage power supply on their web site now.

Thanks for the answers and Roberto it was your hands on and helpfulness and the speed in which you jumped on figuring how to control the WP40 when it came out that led to my decision for a Reef Angel as opposed to the others.

RRJ-45 jack for network connee: Thinking of getting a Reef A

Post by Sacohen »

One more question.

Does the RA+ have a RJ45 jack for network connectivity without WIFI.
My router is right next to my tank.

Hey Roberto,

While we're on the subject, how does the pump adjust speed? Does the control signal affect duty cycle?

No. The controller changes duty cycle on the PWM signal, which is then converted to analog with a low pass filter and applied to the control signal of the pump.

Yes, but how does the pump physically change speeds, at the pump level? I'm not sure how to explain myself.

I don't know internally how the pump does... The pump is sealed and I don't want to crack one open ;)
You can inquiry with the manufacturer.
They provide a +24V, GND and control signal wire. That's what we use.

I sent them an email. After seeing the translation of the instruction manual, I'm looking forward to their response. :mrgreen:
