Protector de sobretensiones para refrigerador
¿Por qué deberías tener protectores contra sobretensiones de energía?
Las corrientes y sobretensiones estables son esenciales para el entorno eléctrico de los electrodomésticos
Es por eso que MIAOLINK ha desarrollado una versión mejorada del receptáculo de sobretensión con un rendimiento más estable y una alarma de zumbador (por debajo del umbral mínimo, o por encima del umbral máximo).
Una fuerte sobretensión de potencia puede causar un arco de corriente eléctrica en tu refrigerador, especialmente aquellos con microprocesadores y placas inversoras son susceptibles de daño, ya que las fuertes sobrecargas de potencia pueden freír estas piezas e incluso derretir algunas de las piezas de plástico.
Mientras que las subidas de energía débiles no arruinan tu refrigerador directamente, puede generar daños incrementales a tu refrigerador, afectando su rendimiento y acortando su vida útil con tiempo extra.
Por lo tanto, un protector contra sobretensiones de alta calidad para electrodomésticos es un artículo imprescindible en todos los hogares
Protección avanzada contra sobretensiones
Este protector contra sobretensiones de refrigerador protege tus aparatos de 120 VCA, como refrigeradores, de problemas de alimentación como disyuntores, interruptores defectuosos, picos de voltaje, sobretensiones, fluctuaciones y apagones. Además de retroalimentación de voltaje oportuna (a través de LED que indican si es normal o no) para transferir alimentos y bebidas para que no caducen y se estropeen, este protector contra sobretensiones del aparato evita daños y reduce los costos de mantenimiento.
Alarma de pitido
Indicadores para normal, alto voltaje (135 VAC), bajo voltaje (90 VAC) y retardo de tiempo. Corta automáticamente la fuente de alimentación cuando el voltaje de la red cae por debajo o por encima del límite. Mientras tanto, el indicador correspondiente también se iluminará, protección de corriente y estado de voltaje de un vistazo.
Función de retardo
Después de una fluctuación de voltaje, una vez que la alimentación vuelva a la normalidad, habrá un retardo de minutos (3/5/10), establecido por ti mismo de acuerdo con la situación real, para confirmar que el voltaje se ha estabilizado para que se pueda volver a conectar automáticamente. Esto garantiza que el equipo no se encienda y apague repetidamente durante las fluctuaciones de voltaje y no esté sujeto a las grandes sobretensiones que normalmente ocurren cuando se restaura la energía después de una interrupción.
Doble enchufe
Nuestro protector cuenta con dos tomacorrientes, protegiendo dos electrodomésticos a la vez. No se limita a refrigeradores; es compatible con varios electrodomésticos como microondas, dispensadores de agua, lavaplatos y mucho más. Esto mejora la comodidad mientras te ahorra del gasto de adquirir

This was easy to wall mount and run the cord to what was the regular plug. I have a refrigerator and stand up freezer in my pantry and this is now the power supply for the two devices.I use UPS devices on all my computer and network devices and when there is any disruption in power service the UPS systems will start clicking and beeping even if I didn't otherwise notice anything wrong with the power. This let me know power interruptions here are more often than the occasional wind storm or ice storm that might knock out power lines. This is a good first step to protecting the two appliances.Setting up is pretty easy. It has color coded indicators to let you know your current voltage status. Selecting one of the three delay preferences is as simple as touching the button and the light above it lights up. These are pantry devices so I set this to 7 minutes and muted the alarm buzzer.I didn't have a storm handy to test the device but I did have a circuit breaker to throw and when I turned the circuit back on and started my timer I saw that in about seven minutes the device reconnected power to the appliances.How much protection from the little things I'm not sure. My UPS devices yell at me for extremely minor fluctuations, but they are protecting digital equipment. The idea behind this protector is useful and it functions as expected under the testing situations I have been able to conduct.

It has an industrial looking orange color and two outlets. I plugged my fridge and another appliance, my portable dishwasher, into it. It has 4 LED lights: red means the voltage is too high, blue means it’s too low, and green means it’s normal. There are buttons for 3, 5, and 7 minutes of delay before turning the power back on after an outage. There’s also a quick restart button to skip the delay. I can press and hold another button to mute the buzzer.I found one inconsistency in the user guide: Under specifications, it says it’s 120V/20A/60Hz, but in the image of the surge protector in the same user guide, I see the amperage listed as 15. So, I'm unsure if the real amperage rating is 15 or 20. But on Amazon it says 15 so I go with that. The back shows the brand is MIAOLINK, and the model is ML-LY1202. The voltage range is 90V to 135V, and it has FCC, CE, and ROHS certifications. It’s for indoor use only and has three screw holes for wall mounting.The cord is thick with a US plug and three prongs. The surge protector feels a bit bulky - I measured it at 4 ¼ inches wide, 3 ⅛ inches tall, and 1 ¾ inches deep. The power cord is about 16 inches long. Seeing UL certification in the specifications makes me believe it’s safe. I hope it will protect my fridge and dishwasher.Currently, the green light shows normal voltage, the yellow light indicates the default 3-minute delay setting, and the red light signals power status.

Ironically enough, a few days after I installed this surge protector, the power in my block went out, and when it did, it went on then off a few times in succession before staying off about an hour. The protector did exactly what it is advertized to do. It went off the first time, and did not come right back on again, instead starting the timer. Once the power came back on, I measured the delay and it was exactly to the second I set it to, and protected the refrigerator and the stand-up freezer I had plugged into the two sockets. Brown-outs (power drops to 70 to 90 volts, but not off, then back to 120 volts), or these quick repettitive on/off events are where you get spikes and surges, and are more damaging to your appliances than just a blackout is (an electronic device will try to draw more power when the voltage drops, like opening a valve wider, then when the voltage jumps right back up to full or higher the valve can't close off fast enough and something in it can get fried). This protector cuts off at 90 volts and starts the timer, which you can set for 3, 5, or 7 minutes (set it according to how bad your power situation is, i.e. long for storms knocking it out often in one sitting, or short for blackouts happening once or twice at a single event). It should also work well to stabilize the current when having to use a portable generator.I had a delayed start installed on my central A/C unit a couple of years ago as well, as the capacitor and fan got burned out by spikes/surges from the power going on and off quickly and repeatedly that summer as the grid was under heavy stress (95 to 102 average temps most days), and the delayed start saved from the same fate last year. Putting this on my large appliances was a no-brainer when I saw it, and it works well. I will be getting more of these.

This looks well made but seems marketed to folks with no electrical knowledge.Does it do surge protection?It doesn't really say since there are no energy or surge specs on the description or on the unit itself such as joules and a minimum "clamping" voltage.It may have an internal flash voltage clamping tube or MOVs (metal oxide varisters).or none. It doesn't say and the circuit board is rather wedged in there with no simple way to take it out to look.The internal components can't be serviced or seen to tell but it seems to rely mostly on a relay to disconnect the load if incoming voltage is out of spec long enough.That takes half a second before it kicks in (as per their spec) which would be much too long to offer protection to a connected device.Voltage spikes tend to be very fast such as 1msec or 1 nanosecond.500mS to turn off is too slow since there may have been 2 or 14 spikes already in that time while it was still connected.Protection that needs 500 mS to engage is typically too late except for a long term over voltage or under voltage condition which is very rare.The power grid in my area gets dozens of short spikes per year and 4 -6 full power outages.Usually 1 -2 seconds but sometimes for hours.A brownout or high-low voltage condition is very rare. Maybe, 1 every 10 years or lessTHAT appears to be the one this is intended for. A condition that never happens.That's why a typical power protection UPS system typically has a switching speed of a fraction of one 60Hz cycle of 8-12 mSec so it can at least try to catch a surge and switch over to battery for the conditions that DO happen more often than we'd like.It has a few delay settings to turn back on which all are pretty long but that's useful.3, 5. and 7 minutes delay may as well be 3, 4, 5 since those are all about the same.I'd prefer settings with more range to it such as 10 seconds, 1 minute and 5 minutes.There are no indicators to show that the protection filters are working or that it has any.Does it handle 2400 joules or 3 joules? Can't tell.The construction look adequate and the 14 AWG power cord is ok.
