Adjustable V/A Protector Over/Under Voltage & Overcurrent Protection Intelligent Relay Reset Protector Voltage Output Stabilizer for Home Office Appliance, AC110V DC85-300V 63A, Din Rail Mount

Buen equipo, he instalado varios de estos... No hay fallos ... Gracias.

Muy bueno

The device seems to work well, but it’s hard to use. In order to see real time data you need to go into the setup menu and half way through the menu option choices it will display the real time data. The unit is rail mount, but it would be great if it could be mounted in a standard single gang box.

I am glad I bought this product. Do the job.

I got this intelligent relay to protect an inverter that lacks built in protections, but had to test it out on the bench and see how it works first.This relay gives you total control over when the device trips; you choose the over/under voltage and over current at which it trips, how long those overages have to be sustained before it trips, and how many times it will automatically reset before staying off. You can also choose the amount of time it waits before automatically resetting. A countdown timer is displayed after it trips. See the pic of all the menu options. You can easily turn the circuit on and off with the small power button on the relay. The display is always on, even when the circuit is turned off. It will dim if Energy Saving Mode is turned on, but I could not find a way to turn off the display completely.Changing settings is easy provided you have the instructions in hand. Press the menu button until you get to the number of the option you want to change, then use the up and down arrows to change the setting. Without the instructions in hand, there is nothing to tell you what option the menu numbers correspond to.The miniature circuit breaker form factor integrates easily into small solar setups. The DIN rail mount was a bit loose on the thin DIN rail in the housing I am using. It wiggles around and slides, but will not come loose. It probably holds tighter on a proper thickness steel DIN rail. The humidity rating of ≤50% may be some cause for concern in mobile applications.I tested it by connecting a heat gun that would draw 2A on medium and 9A on high and setting the intelligent breaker's threshold set to 7A sustained for 1 second. It performed perfectly every time, tripping after one second of the heat gun on the high setting. Then a timer on the relay would count down and it would reset. The automatic reset feature can be disabled if you prefer.I really like the device. It does exactly what I need, does it well, and will change if my needs change.

I'm a retired electronics technician, and I've built an electronics bench to design, build and test all things electronic. On an electronics workbench like mine it's all about the power! I have several 20A lines feeding the bench to feed everything from test equipment to charging equipment. However, you never try and pull a full 20 amps from one receptacle. You CAN and sometimes get away with it, but you're pushing the limits. When it comes to electronics, you don't want to "push it" too much because the consequences CAN be pretty destructive, up to and including starting a fire! It's one thing to fry a piece of equipment or trip a breaker, but it's an entirely different ballgame when you start seeing smoke coming from somewhere on your circuit board because somehow there is way too much current (amps) flowing through something. Perhaps one of the components simply fails. Film capacitors are often the culprit because of the way they are designed and manufactured. I've had several cheaply made ones simply "POP", and start smoking.Along comes this gadget that I did not have before. It allows you to set a specific amount of current (amps) to flow until the circuit breaker trips and stops the mayhem. If nothing else, this gives me more piece of mind knowing there is another layer of protection, and one I can actually tweak and set. Those breakers in your fuse box, especially if they are older than say 10 years, can and do fail. I have a 20 amp breaker fail to trip years ago. If I had not noticed the smoke coming from one of my 12-2 house wiring that happened to be exposed on a rafter and not hidden inside a wall somewhere, it may have caught fire. Upon investigating, I found that the breaker simply didn't trip!Bottom line, this is a great addition to my workbench. So far, although there was a slight learning curve setting it up how you want it, it has worked flawlessly. I give this five stars and would recommend this for your workbench full of tools and electronics.

No lo pruebo aún, cuando lo haga, escribiré sobre este artículo

Muy buen producto, y fácil de instalar (para los profesionales en electricidad)
