Test on-line UPS Socomec NRT-U3000

Today we look at a sufficiently powerful model on-line UPS Socomec series NETYS RT, the potential of which is 3000 VA. Recall that the 3000 VA is approximately equal to 2.1 kW, which allows the use of NRT-U3000 protection for small office, as the typical power consumption of a computer is about 200 ... 300 watts. Device still offers the convenience of use and multiple configuration options. Thus, the battery life in this case can be increased several times by installing additional battery packs in the amount of 4 pieces. If they wish to receive an unprecedented level of protection is possible installing extra charger, which can increase the number of modules, battery up to 12 pieces, the battery life with the tens of hours.Scope of supplySpeaking of packaging, just want to warn potential buyers. The fact that the size of the box impressive, the more weight, so it can only be transported in a car, and move together. Inside you will find a familiar feature:- UPS NRT-U3000;- Cable for connection to the power supply;- Two cables for consumers;- Interface cable RS-232;- Part of the team of plastic stand;- A set of metal brackets for rack mounting;- Paper and two disks.Appearance and designAppearance of this model is virtually no different from those already examined sample output 1.1 and 2.2 kVA. Housing is still metal, material thickness about 1 mm from the outside is covered with a practical, non-marking paint. Increase energy capacity, it only affects the external dimensions.Indoor Installation can be done in two ways: horizontally and vertically. Vertical version on the floor of the assembly requires a special attachment, which consists of two side poles and four feet. For installation just use four screws supplied. The standard width of attachment may vary in half. When set to minimum, it is the width of the UPS, this option is used when only one source. If the office has two similar bespereboynika or one of them works in the sum with an additional battery pack, they can be installed in a single mount, creating an array. Horizontal mounting option provides a standard rack. All necessary mounting the supplied is.Located in front plastic cover, in the center where you can see a small control panel. Here at your disposal are two buttons and several LEDs that indicate the operating mode and show basic information about the source of a percentage. It is very convenient when you can see the power of the connected load, instead of guessing, "pull" this UPS another computer or not. Plus, this has several features configuration and fault indication. For example, you can set the amplitude of the output voltage, and when a fault appears her light code that can be easily decrypted using the user's manual.Connectors to connect to the network and switching customers at the rear of the panel. Source has multiple outputs. Two of these groups are represented by standard plug to three pieces, each of which admits a maximum current of about 10 A. If the power of the consumer is too large, it is better to use the third output connector to 16 A. It is near universal connectors for the protection of network and telephone equipment and EPO jack for the emergency stop button. Local connection to PC via USB and RS-232. Small connector, closed the lid, is designed to connect an optional battery pack, which increases the battery life.Internal structure of the source is very similar to the previous model, the harp so it is not worth the attention. Boards are mounted very high quality, carefully laid wires. Radiators, which are attached to the power components, form a kind of tunnel, which is blown cooling system, built using a 80-mm fan. Battery six pieces, it is well known to us HR9-12 Company BB Battery. Producer allows any option to install the battery, because batteries contain positive and negative plates, separated by glass fiber separator soaked with electrolyte. Therefore, for any installation option life of the product is reduced.Practical testingLet's start with the fact that, in reading past reports on the testing of models and NRT-U1100 NRT-U2200, it is possible to form a view about the source under consideration today. In fact, he is deprived of any significant deficiencies and disadvantages of the available can be classified as secondary.The amplitude of the output voltage of the default is 230, the deviation from the nominal value shall not exceed ± 1 for all loads and modes. Recall that the output parameters can be configured for compliance with 230, 240, 200, 208 and 220 V. The battery life is acceptable. At half-load NRT-U3000 operates from battery about 14 minutes. If the load is 90% of maximum, the time is reduced to five minutes. It is easy to calculate that 90% of the 2.2 kW is more than enough to power six or seven standard office computers, which will comfortably complete the whole office. If the exit of the model will be connected to only a few machines, with the loss of power at the outlet they will be able to work more hours. If you want, even this time can be increased by using the optional battery pack.Reliability of the device does not cause absolutely no fear. Radiators power components are not heated above 70 degrees Celsius. In addition, each of the radiators has a separate temperature sensor, which adjusts the fan cooling system. The noise generated by the cooler, tangible and unpleasant. Metering special device Center 321 1 meter shows that the level is at around 45 dB (A). But here again we repeat that in the office, and even more so the server room is absolutely not important.ConclusionAs a result, we can say today that the tested UPS NRT-U3000 proved to be a source of high quality made with good electrical properties. Due to the use of the double conversion, it provides unprecedented protection and high battery life. Negative moment can be considered only increased noise, but on the other hand the device operates in the optimum thermal conditions.In general, the line NETYS RT offers a good choice of quality on-line solutions, depending on the capacity of the protected equipment.
