DEWIN KWh Din Rail Meter, Single Phase Energy Meter, 220V 5(80) A Digital 1-Phase 2 Wire 2P DIN-Rail Electric Meter, Electronic KWh Meter

A DEWIN DIN rail power meter—this is an absolutely fantastic piece of equipment. Really fantastic. If you care about electrical systems, energy monitoring, or just knowing what’s actually going on inside your setup, this is the kind of device that changes everything. First of all—DIN rail systems are brilliant. Absolutely brilliant. Everything is clean, modular, professional. And this meter fits right into that ecosystem perfectly. It snaps in, it integrates, and suddenly your electrical panel goes from “guesswork” to full visibility. Now let me be clear—this is where things get exciting. Because once you start measuring power properly, you realise what’s actually happening in your system. Voltage, current, wattage, energy consumption—it’s all there. Real data. Not estimates. Not assumptions. Real numbers. And I love real numbers. I really do. This device gives you that control. You can see loads in real time. You can identify waste. You can optimise systems. Solar, battery setups, workshop circuits—everything becomes clearer and more professional. And I’ll say this strongly—this kind of monitoring is what serious electrical work looks like. No more guessing. No more “it should be fine.” You know exactly what is happening at any moment. That’s powerful. The display is straightforward and functional. Not overcomplicated. You don’t need complexity—you need clarity. And this delivers it. Clean readouts, accessible information, and quick interpretation. Installation on DIN rail is, of course, excellent. Very satisfying. Click in, wire up, done. Everything aligned. Everything structured. I’ve said it before—DIN rail is one of the greatest industrial standards ever created. It just works. Now I have to say something—once you start using meters like this, you become obsessed with monitoring. In a good way. You start checking loads, tracking usage, understanding your systems at a deeper level. It’s extremely engaging.

Works fine good value

Bought this to indicate electric usage when charging my electric vehicle. Works fine.

Needed reading to be visable when power is off. Bought mecanical type for C2L car supply.

A light compact DIN-Rail mounted 2-module-wide digital meter, which shows Voltage, Current, Watts and Watt-Hours in a rotating flashing display. Easy to fit, just 2-Wire Live and Neutral at the top and bottom.

Used on a 4Kw heater since June and so far recorded just over 1000Kw. Today it melted!

It’s good value and easily fixed. The build quality doesn’t seem great. The terminal size is quite small.

LCD is burst in a year

OTTIMO PRODOTTO , QUALITà RAPPORTO PREZZO BUONI ,NULLA DA DIRE A SFAVORE

Super funktioniert

Bom , só não tem reset

fonctionne très bien mais une fois mis dans le tableau, il est difficile de lire les chiffres sans une lampe de poche.

Utilisé pour mesurer la consommation d'un circuit d'une prise de recharge Green'Up de véhicule électrique. Je n'avais pas besoin de mémorisation des mesures, ni de comptage partiel, ni de "télérelève" ni d'aucune fonctionnalité très évoluée. Mon objectif était de vérifier manuellement et ponctuellement les conditions de recharges et notamment le courant (et donc la puissance). Ce petit compteur fait le boulot ; la précision à l'air correcte même si je ne l'ai pas comparée à celle d'un "vrai" appareil de mesure étalonné. Pas de rétroéclairage (mais ça me va très bien) ; affichage cyclique tension, courant, puissance, énergie. Une étoile en moins car l'origine de l'appareil n'est pas claire même s'il semble avoir fait un détour par l'Allemagne ; on se demande donc toujours si la conception est en phase avec le niveau d'exigence CE et/ou NF.
