Measuring range: 0-99.9V

Load capacity: relay normally open port Maximum load capacity: DC 0-30V / 10A, AC 0-250V / 10A

Relay normally closed port Maximum load capacity: DC 0-28V / 10A, AC 0-125V / 10A

Module interface:

Input end

1, DC +: positive DC power supply

2, DC-: DC power supply anode

3, V +: measuring voltage positive

4, V-: measuring the negative voltage

Relay load output:

1, NO: relay normally open interface, the relay pull before the open, after the suction with COM shorted

2, COM: relay common interface

3, NC: normally closed relay interface, the relay before the short circuit with the COM, pull after the vacant

No instructions. Scanning the QR code on the units packaging does not work either.I contacted them about getting instructions, and the reply said they would contact engineering and I would have to wait a couple days.LOL, seriously?They SHOULD NOT BE SELLING items when they cannot provide instructions or even a link to them!Internet search provided little help except for one source.I did find the printed instructions.I am familiar with comparators having built many from scratch in the 80's and 90's.However, the instructions are so poorly translated that I found it ridiculous.By the time I could figure them out, I could have built my own but, this unit is less expensive than making it myself. And time is money as well.HOWEVER, there is a guy on youtube with the solution!When there, search for Yvoa1sThnMI or Multi function Voltage Monitoring Controller DVB01 and watch Teals video.Very drawn out but, excellently explained.Without that video, this unit would be returned.Covers everything except the voltage calibration which, was off by 1 volt.A great video on how to use this device which, works well and has a programmable delay to prevent hysteresis especially when using LiFeP04's.Okay, the setup is a bit fidgety and holding the Set button down takes longer than a second.However, once configured, you can use it as high, low and window at voltages settable down to 1/10 increments.I am using this unit to turn off my 3000watt power inverter (XWJNE 3000 Watts Power Inverter) when the batteries discharge to a specific low voltage.Then turn it back on when batt voltage is charged back up to where I desire.(YOU OWN ONE of these XWJNE inverters? Pins 1 & 2 on the units remote cable port are the switch you want to control by this relay! You're welcome!)Since the inverter loudly alarms when it turns itself off due to low batt, usually 3-4AM, I needed to rectify that issue.I have the unit wired to also switch my Automatic Transfer Switch to Mains at whatever voltage I want at the same time as the inverter shutdown.Actually, with this little comparator, you don't even need an ATS because this works better. You just need a DPDT relay with contacts capable of your load. I would recommend twice your load.Thanks to the independent video! NOT their support! I can use this unit.So, so far this little module is working well! Hopefully it lasts a long time because it works well.

Item arrives with no instructions. Go to YouTube and search DVB01.

The instructions are poor but tolerable. Read them carefully as the translations are not technical. As an example, they use the term "suck" to mean relay activated. The operation of the unit is great. One small issue is that the display reading can be calibrated. The calibration doesn't apply to the actual measurement which can give an offset. As an example: if I correct the display to read an actual 50vdc when it was reading 51vdc and If I want the unit to trigger at an actual 50vdc, you need to set it to 51vdc for V1 or V2.

Voltage reading jumps all over the place with no loads connected. Don't think I would trust this device to keep my batteries from over charging.

Does not have a capacitor to smooth out voltage noise. Get the DVB100. Much better. Using it on my solar.

I liked that it also could measure the voltage source that it is running from. This was a little unexpected because of internal references. I am using it to disable the output of an inverter when the voltage gets below a certain point and to re-enable the inverter output after the battery voltage returns to a higher level. Disable at less than 11.0 volts and re-enable at greater than 12.5 volts. This prevents the inverter from shutting down and turning on at its designed shut down level and cycling on/off, on/off during the transition.

Utilisé pour protéger un appareil. Je dois empêcher l'activation d'un équipement électronique entre 0 et 10 volts à l'aide du relais de ce module. Et ça fonctionne vraiment bien.
