Review: easy to read - works well, east install, BRIGHT display. great value Review: Medidor de calidad - Despues de 12 años de uso, ha dejado de funcionar mi medidor Ketotek, me mide parcialmente por que un condensador ha calentado el cable plano qye lleva en su interior, tenia el sencillo, sin contador. Ahora he comprado el superior, wue tiene contador, y va perfectamente, facil de instalar y con instrucciones. Medicion exacta. Recomiendo el producto. El tamaño viene a ser tres magnetotermicos DPN. Es muy facil de instalar no necesita ser electricista pero si debe mantener unas medidas de seguridad, desconecte la electricidad del ICP o del Termico general de entrada. Mida que no haya corriente y siga las instrucciones de montaje. Puede pasar por el orificio tanto la fase como el neutro, solo uno. Tiene que alimentar desde el termico de alumbrado 10A con cable de 1.5mm el medidor Ketoket, en el tornillo 1 fase, en el 2 neutro. Si la instalacion es antigua puede ponerlo en cuadro ICP. Si es mas moderna en su cuadro y si no cabe, en uno exterior encima del cuadro. Pude ponerlo delante o detras del diferencial pero siempre protegido por delante de un termico y su alimentacion al de 10A.espero wue le pueda servir a slguien mi explicacion. ## Features - 【High quality & safety】KETOTEK power meter is made of high quality ABS flame retardant material and high precision chips to ensure safe use. - 【6 in 1 Multimeter】One interface displays 6 kinds of measurement parameters at the same time, including voltage: AC 40.0-300.0V, Current: AC 0-100.0A, Electric power: 0-30000W, Energy: 0-99999kwh, Frequency: 45.0Hz–65.0Hz, Power Factor: 0.00-1.00PF. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B095LYZWYV | | ASIN | B095LYZWYV | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #255,461 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #152 in Power Monitors #614 in Voltage Testers | | Color | multiple colors | | Customer Reviews | 4.6 4.6 out of 5 stars (2,050) | | Customer reviews | 4.6 4.6 out of 5 stars (2,050) | | Date First Available | 18 April 2022 | | Date First Available | 18 April 2022 | | Included components | Energy Meter, User Manual | | Item Package Quantity | 1 | | Item Weight | 141 g | | Item model number | D52-2047HD | | Item model number | D52-2047HD | | Manufacturer | KETOTEK | | Manufacturer | KETOTEK | | Part number | D52-2047HD | | Product Dimensions | 5.4 x 6.4 x 8 cm; 141 g | | Product Dimensions | 5.4 x 6.4 x 8 cm; 141 g | | Voltage | 230 | ## Images ![KETOTEK Energy Meter AC40-300V 100A, Digital Display LED Voltmeter Ammeter Active Power Factor Gauge, Volt Amp Watt Current Frequency KWH 6in1 Multifuction Meter Din Rail (Built-in CT) - Image 1](https://m.media-amazon.com/images/I/71B6ThjtsQL.jpg) ![KETOTEK Energy Meter AC40-300V 100A, Digital Display LED Voltmeter Ammeter Active Power Factor Gauge, Volt Amp Watt Current Frequency KWH 6in1 Multifuction Meter Din Rail (Built-in CT) - Image 2](https://m.media-amazon.com/images/I/61LCgEx7LpL.jpg) ![KETOTEK Energy Meter AC40-300V 100A, Digital Display LED Voltmeter Ammeter Active Power Factor Gauge, Volt Amp Watt Current Frequency KWH 6in1 Multifuction Meter Din Rail (Built-in CT) - Image 3](https://m.media-amazon.com/images/I/61BBTc8+TZL.jpg) ![KETOTEK Energy Meter AC40-300V 100A, Digital Display LED Voltmeter Ammeter Active Power Factor Gauge, Volt Amp Watt Current Frequency KWH 6in1 Multifuction Meter Din Rail (Built-in CT) - Image 4](https://m.media-amazon.com/images/I/616L5N2oQ3L.jpg) ![KETOTEK Energy Meter AC40-300V 100A, Digital Display LED Voltmeter Ammeter Active Power Factor Gauge, Volt Amp Watt Current Frequency KWH 6in1 Multifuction Meter Din Rail (Built-in CT) - Image 5](https://m.media-amazon.com/images/I/61-iyS17kqL.jpg) ## Questions & Answers **Q: For the averages can this meter run in reverse if monitoring the AC side of solar inverters? If not, does anyone have a suggestion for one that can?** A: No, this meter can not run in reverse. **Q: Does this measure rms or average ac?** A: This energy meter measures rms. **Q: This seller is selling a device that cannot accurately measure power in a us based household. only one "hot" lead is being measured and a house panel** A: So use two and add them together. **Q: How many power meters do i need to monitor: phase 1+ n (110v), phase 2 + n (110v), and phase 1 + phase 2 (220v)?** A: hi it depends on your requirement. You can only use one meter to monitor one of the phase + n . Or you can use three meters to monitor each phase + n . ## Customer Reviews ### ⭐⭐⭐⭐⭐ easy to read *by R***S on 29 January 2026* works well, east install, BRIGHT display. great value ### ⭐⭐⭐⭐⭐ Medidor de calidad *by J***B on 9 August 2026* Despues de 12 años de uso, ha dejado de funcionar mi medidor Ketotek, me mide parcialmente por que un condensador ha calentado el cable plano qye lleva en su interior, tenia el sencillo, sin contador.
