XPR3SS Taxnele 3 Phase 100Amp Automatic Voltage And Current Protection Relay Voltmeter Adjustable Over Under Voltage Current Protection Voltage & Amp Meter Surge Protector Phase Unbalance Protection

This product is multifunctional, combining several features into a single device. It serves as an energy meter while also offering over/under voltage protection, overcurrent protection, and leakage current protection—functions typically handled by separate devices like RCCBs. Essentially, it consolidates multiple devices into one, which is quite convenient. So far, the smart meter has performed well, and I’m satisfied with its functionality. I’ve tested its voltage, current, and leakage current protection features, and they work as advertised. The auto-reconnect feature is particularly useful, as it automatically restores the connection once the fault condition is resolved. Wi-Fi connectivity has been reliable, with only one instance where the device went offline. Restarting the main power supply resolved the issue quickly. The device’s display provides most of the essential information, although it doesn’t show real-time power usage (kW). To view this, you either need to calculate it manually using voltage and current readings or check the Smart Life app. The app offers useful statistics such as daily, monthly, and yearly kWh consumption graphs. However, it would be even better if it also tracked and displayed trends for other parameters like power, voltage, current, and leakage current. Device settings can be configured either directly on the unit or through the app, which adds flexibility. That said, the app’s font and color scheme—especially on the energy statistics screen—could be improved for better readability. Hopefully, future updates will include customization options for the theme. The leakage current protection feature is excellent and can be disabled if needed. During testing, I noticed that while voltage and current protection alarms were logged correctly in the app, the leakage current alarm wasn’t recorded—likely a bug that needs addressing. One caution regarding the “Remote ON/OFF” feature: while you can turn the device off remotely via the app, turning it back on isn’t possible if your Wi-Fi router is powered by the same supply. In such cases, manual intervention is required to restore power. Overall, it’s a solid product and I’ve had no issues so far. I hope it continues to perform reliably over time. For configuration-related queries, I contacted the seller and was impressed by their prompt and helpful response. They even provided a video demonstration, which made the setup process much easier.

Here is what this multifunction meter AT4PW by Atorch has. Pros: -- BIG bright display with display rotation feature -- 100A Relay (Ofcourse not tested with this hige load). But terminal blocks and relay operation appears excellent. -- Over Voltage Protections - Yes -- Under Voltage Function - Yes -- Over Power Protection (Cut outout If wattage is high) - Yes -- WIFI and Mobile Operation - Yes (SmartLife OR TUYA) -- Temperature Function - Yes --- Can be automated to switch off if temperature is above threshold ... -- Scheduler / Timer for auto switch on switch off - Yes (With Smartlife App or TUYA app) -- Good customer support by whatsapp. Cons: -- AQI, PM, Humidity sensor - Does Not exist evnthough it is advertised as existing. One reason I chose to give a 4 star instead of 5. An honest listing always helps. -- Leakage Current function - Does not exist. This parameter protects the home from an accidental electric shock. A must have feature. In fact i kept on searching for this and have to return many products falsely claiming this feature. This one does not claim to have. So no misrepresentation. However it would have been an excellent all in one with this feature. Hope supplier will see to it. This review is very similar to near similar small form factor ATORCH other model with smaller display. Overall an excellent buy and good customer support. However i could not keep the product since my requirement was not fullfilled. Bought that for ore sensors being advertised than it's smaller cousin model. Since i already own the smaller model and it is same....no point keeping it.

"I’ve been using this voltage protector for a few weeks, and it performs exactly as promised. It reacts quickly to voltage fluctuations and keeps my appliances safe. Build quality is solid, installation was easy, and it gives clear indicator lights. Definitely worth the money!"

This seller three times sent me this Sigma DSP voltage protector and all 3 were defective. They were not even powering ON on connections to the mains voltage.

Great product working absolutely fine.

Best my product and best and delivery thank you my jaan Amazon

Good device to monitor electrical parameters (current, voltage, kilowatt hour, power factor, and power). installation was hassle free. It offers good readability from long distances. Overall a very good product.. need to assess and wait until its warranty period for its reliability on the long run 🙌

I recently purchased KWS-306WF, got it installed yesterday. So far, it is looking good; it is connected to my WiFi, and I can track energy consumption and operate connected devices remotely. It's ideal for people who want to control the electricity consumption of electric products, especially those who can't be physically present. Built quality is good. I feel that they should give a better manual on how to get started with wifi, as there is no mention of usage with the Smart Life app and how to configure it. For beginners, it will become difficult to get started. A video will definitely help.
