Analog Energy Meter

Product Details

Application

Model DEM011TK single phase electronic DIN rail active energy meter is a kind of new style single phase two wire active energy meter. It has adopted micro-electronics technique, imported large scale integrate circuit, and used advanced technique of digital, SMT techniques, and etc. The meter completely accords with relevant technical requirements of class 1 single phase active energy meter stipulated in international standard IEC 62053-21. It can accurately and directly measure 50Hz or 60Hz active energy consumption from single phase AC electricity net. It can display total energy consumption by step motor type impulse register. It has following features: good reliability, small volume, light weight, specious nice appearance, convenient installation, and etc. This meter has already gotten the patent certificate from China State Intellectual Property Office at present. Patent certificate NO. ZL 2006 3 0106828.1. All the other country patent certificates are in processing.

Functions and features

● Either 35mm standard DIN rail installation, complying with standard DIN EN50022, or front board setting (mounting holes center distance 63 mm), users can choose by themselves.

● Six pole width (Modulus 12.5mm) complies with standard JB/T7121-1993.

● There is standard configuration 5+1 digits display (99999.1kWh) by step motor type impulse register. If choosing 6+1 digits display, the product configuration code is AK.

● Standard configuration features one port of pulse output passive (polarity). Feel free to select distant port of pulse output passive (nonpolarity), the configuration code of which is AI. Both contact with all kind of AMR system conveniently，complying with standard IEC 62053-31 and DIN 43864.

● Two LED indicates respectively power supply state (green) and signal of energy impulse (red).

● Standard configuration doesn’t detect direction of the current flow. But automatic detection of the direction is optional that is indicated by the red light. (When only red signal working, that means the direction of the flow of load current reverses).

● Single direction measures single phase two wire active energy consumption and it has nothing to do with direction of the flow of load current, complying with standard IEC 62053-21.

● Directly connect operation. 

● Standard configuration retains short terminals cover, and you may select extension terminals cover, in order to protect your circuit and users’ safety. (The code of the safer product configuration is TL).

You may want to know why travel should be considered an essential human activity.

Travel is not rational, but it’s in our genes. Here’s why you should start planning a trip now.

Travel is not a rational activity. It makes no sense to squeeze yourself into an alleged seat only to be hurled at frightening speed to a distant place where you don’t speak the language or know the customs. All at great expense. If we stopped to do the cost-benefit analysis, we’d never go anywhere. Yet we do.

That’s one reason why I’m bullish on travel’s future. In fact, I’d argue travel is an essential industry, an essential activity. It’s not essential the way hospitals and grocery stores are essential. Travel is essential the way books and hugs are essential. Food for the soul. Right now, we’re between courses, savoring where we’ve been, anticipating where we’ll go. Maybe it’s Zanzibar and maybe it’s the campground down the road that you’ve always wanted to visit.

It’s not the place that is special but what we bring to it and, crucially, how we interact with it. Travel is not about the destination, or the journey. It is about stumbling across “a new way of looking at things,” as writer Henry Miller observed. We need not travel far to gain a fresh perspective.

No one knew this better than Henry David Thoreau, who lived nearly all of his too-short life in Concord, Massachusetts. There, he observed Walden Pond from every conceivable vantage point: from a hilltop, on its shores, underwater. Sometimes he’d bend over and peer through his legs, marveling at the inverted world. “From the right point of view, every storm and every drop in it is a rainbow,” he wrote.

Thoreau never tired of gazing at his beloved pond, nor have we outgrown the quiet beauty of our frumpy, analog world. If anything, the pandemic (COVID-19) has rekindled our affection for it. We’ve seen what an atomized, digital existence looks like, and we (most of us anyway) don’t care for it. The bleachers at Chicago’s Wrigley Field; the orchestra section at New York City’s Lincoln Center; the alleyways of Tokyo. We miss these places. We are creatures of place, and always will be.

After the attacks of September 11, many predicted the end of air travel, or at least a dramatic reduction. Yet the airlines rebounded quickly, and by 2017 flew a record four billion passengers. Briefly deprived of the miracle of flight, we appreciated it more, and today tolerate the inconvenience of body scans and pat-downs for the privilege of transporting our flesh-and-bone selves to far-flung locations, where we break bread with other incarnate beings.

So go ahead and plan that trip. It’s good for you, scientists say. Plotting a trip is nearly as enjoyable as actually taking one. Merely thinking about a pleasurable experience is itself pleasurable. Anticipation is its own reward.
