DISTINCTIVE FEATURESMercury 201.5 5 (60) A / 230 V single-rate

• DIN rail mounting.
• The meter measures analog input signals digitally.
• Measurement of instantaneous power, current, voltage.
• Information display device - LCD indicator.
• A shunt is used as a current sensor, which ensures the required accuracy of measurements in the presence of a constant component in the load circuit or when the phase current curve deviates from a sinusoid.
• There is a modification with a built-in PLC - modem for operation as part of the AISIS “Mercury - Energouchet” and other systems.
• Programmable galvanically isolated telemetric output (DIN43864).
• The counters work towards increasing readings for any disruption in the phasing of the current circuit connection.
• The function of controlling and controlling the load through the telemetric output by external switching circuits to limit / disconnect the load of the consumer when the limits are exceeded.
• Small size.
• It is completed with a transition plate with connecting dimensions of induction meters.

And its modifications are made at the facilities of the Russian company LLC Incotex-SK.

The main activity of this company is the production of electricity metering devices, ranging from the simplest single-phase electric meters of the type Mercury 201, Mercury 200.02 and ending with complex multi-field, three-phase industrial meters of the type Mercury 230, Mercury 234. The brand Mercury is known to consumers since 2001.

We all remember the old black electric meters with a rotating disk, which counts the power consumption of the calculating mechanism “rumbling” at night. But as time goes on, everything changes, the means of energy accounting change accordingly. Now practically you will not meet old morally and technologically obsolete meters. They were replaced by more advanced models. Electric meters of the Mercury 201 series are just these representatives.

The Mercury 201 Mercury 201 series is represented by several modifications and has the following specifications 201.2, 201.22, 201.4, 201.5, 201.6.

They differ among themselves depending on the permissible operating current, as well as the method of displaying information.

Design features Mercury 201.5

All representatives of the series of meters 201 are made in the same rectangular plastic case. On the front panel of the device (on the left side) there is an LCD display of information display (or “drums” of electricity counting), on the right side there is a “plate” with the main technical parameters. The case itself, and accordingly the device itself, is quite compact and has dimensions of 105x105x64 mm (weight on the order of350 g)

The bottom panel of the housing is removable - it performs the role of protecting the device contacts. Connection of wires to these contacts is carried out by screw connection.

As for fixing in the panel or on any other surface, the electric meter mercury 201.5 is fixed using the so-called DIN-rail. Leading manufacturers consider this method of installation to be the most rational, because today, most metering devices are fixed precisely at the expense of such a rail.

Characteristics of the electric meter Mercury 201.5

Considering the main technical characteristics of the electric meters Mercury 201, it should be noted that these devices have special protection against theft of electricity by reversing. That is, it can be argued that the methods of stopping the meter by changing the “phase to zero”, which the Internet is full of, are simply unfounded.

The table shows the main technical characteristics of electricity meters Mercury 201

Many consumers of electrical energy are faced with the replacement or installation of a new meter of electrical energy. The reasons for replacing (installing a new one) can be many: the mismatch of the accuracy class requirements for commercial accounting of the retail electricity market;  Expired expiration date, verification; mechanical damage; connecting a new garage, home, apartment and the like. Consumers are wondering: "What counter to deliver? Which is better, cheaper, safer, more beautiful?". There are many offers on the market. From personal experience, I note that when buying an electric energy meter, it is difficult to say which one will work without any complaints and the whole service life will not stop in a month, a year. In my practice (more than 12 years), both very expensive (with GPS, etc.) and the cheapest (400 rubles each) stopped a few years after the installation of metering devices. So here as lucky. Anything can happen to any counter, for which there is a guarantee.

At this time, most single-phase (220 V) consumer-level consumers stop choosing an electricity meter. Citizens justify their choice by the cheapness of this device, small overall dimensions, good appearance, and the ability to install on a din-rail in popular, inexpensive boxes.

The accuracy class of the counter Mercury 201.5 is 1, in the photo above it is the number 1 in a circle.

Before buying, you should pay attention to the date of production of the meter, it usually coincides with the date of the initial calibration. I came across online treyd.ru from December 8, 2015, that is, at the time of purchase they were about 3 months old - this is excellent. The manufacturer puts the production date directly on the box, you can find out without opening, without printing.

You should also pay special attention to the presence of various stickers, seals, stamps, the absence of which is unacceptable:

Installation of this counter is very simple.

For starters, remove the "terminal" cover:

1. Turn off the screw.
2. We insert, for example, a small screwdriver into the holes.
3. Remove (bottom of the cover up) and remove the cover.

If anyone has forgotten the simplest connection scheme, there is a reminder note on the cover in the form of a meter connection scheme. Connect the wires according to the scheme.

There is a perforation on the terminal cover that is easy break out or bite, then the cover is tightly inserted and screwed into place.
