In the telecom network, due to various reasons, the network can not achieve full coverage. In order to solve the network coverage, reduce the investment cost, shorten the construction period, in recent years there has been a lot of outdoor telecom station, repeater, micro cellular and other outdoor telecom equipment, the demand of outdoor rated UPS is also significantly increased. In addition, with the start of 3G, the telecom market will invest a lot of money for the construction of 3G network, which provides a rare opportunity for the development of outdoor UPS. However, whether the quality of outdoor UPS can withstand the test of wind and rain, is a problem that every manufacturer must face.

These base station equipments are generally placed outdoor, and installed in the roof or mountaintop where the power supply quality is bad, need to consider the influence of high and low temperature to the equipment, because dust accumulation will reduce the insulation performance of the system. In particular, the greater the harm of oily dirt, easy to cause the circuit board short circuit, poor contact, metal corrosion and other damages, is not conducive to long-term stable operation of the system. At the same time, surge, voltage spikes, voltage sag, frequency offset, power interruption and other problems in power grid. The harsh outdoor environment put forward higher requirements for the protection, reliability and stability of the outdoor UPS.

As a solutions and services provider for global telecom industry, SOROTEC engaged in research for many years, SOROTEC UPS products in the industry-leading level. For the situations as the base station distribution area is broad, the quality of power supply is uneven, and the natural environment is very bad and so on, SOROTEC launched the HW9110 series outdoor integrated UPS.

First of all, the SOROTEC HW9110 series outdoor integrated UPS and use of on-line intelligent structure, while power input end use voltage advanced multiplying power factor correction (PFC) technology, has good shock resistance and load capacity, can eliminate the interference of power grid peak and noise to calls, provide better protection for power supply equipment.At the same time, make full range of input power factor higher than 0.99, increase utilization efficiency of electric power, completely eliminate the UPS harmonic pollution on the power grid, reduce the operation cost.

Secondly, in view of the special working environment of outdoor UPS, its performance to play an effective role, there must be a solid protective measures against wind and rain. SOROTEC HW9110E High Frequency Outdoor Online UPS with Air Conditioner protection grade reaches IP55, the box adopts double-layer structure, the rainproof cover is installed on the top, a temperature control cooling fan is installed internal. When the temperature is above 40 degrees, the cooling fan starts automatically, and automatically close below 40 degrees, ensure that the host still work stable under the sun. The unique structural design, excellent heat insulation, waterproof, dustproof, moistureproof function, can provide security for every telecom power supply system.

In addition, the SOROTEC integration UPS adopts double door structure, the door adopts embedded design, concealed door hinge, lock rod, anti-theft locks, the sturdy box and fixed base. The base can be directly fixed on the platform by M12 screws, and the connection between UPS and outside can be introduced through the waterproof holes on the side.

Finally, the SOROTEC HW9110 series outdoor integrated UPS with the function of unattended and warning signal, when the city power is off, UPS enabled battery power supply, and ultimately due to battery undervoltage and automatically protection shutdown. When the city power is restored, UPS detect city power voltage and frequency are in the normal range, if it is, then UPS start power supply to the load; when the city power voltage and frequency in the normal range, UPS is only starting charger to recharge the battery until the city power voltage and frequency returned to normal range, UPS automatically start to load power supply. In addition, SOROTEC UPS can show different working environment, different working conditions through the LED display. LED display can provide some common fault code, by referring to the fault code look-up table, you can quickly determine the cause and fault location of the failure, so that the maintenance of UPS can be more convenient and quick.

Sine wave (or pure sine wave) , the waveform is the same to which output by generator or power grid, and even more perfect than the power grid. But sine wave modulation is not a simple matter, need the complicated control circuit; the cost is bound to rise. Therefore, sine wave UPS generally only in the units which capacity is more than 5KVA, or online units or part of the online interactive units, or the back-up units which capacity is large.

Sine wave has the most efficient conversion to the power frequency transformer, can load all equipment on the market. But because of the cost, there are also many uses such as: modified sine wave sine and square wave, which is not a sine curve, but many small segments, using artificial methods make them like about a sine curve, which is modified sine wave sine, although it is better than square wave, but still not as good as the sine wave.

Square wave is more easy to make, but because the square wave from the highest point suddenly fell to the lowest, and the energy loss is huge, and if the unit capacity is large, the loss may cause the machine damage itself, so the square wave system generally does not in a big unit, and is usually in hundreds of small capacity and reserve unit voltammetry modular UPS uninterruptible power supply.

Sine wave conversion efficiency is the highest, the minimum loss, followed by modified sine wave, and then square wave.

Any power supply in the use process has its set of rules and methods, scientific use can let UPS power supply life longer.
1.Maintain the industrial UPS power supply regularly. Clear the dust inside the machine, measure the voltage of the battery, replace the unqualified battery, check the fan running, detect and adjust the system parameters of UPS.
2.Prohibit overload use. UPS power supply maximum boot load is best controlled within 80%, if overload use, in the inverter state, often breakdown inverter triode. Practice has proved that for the vast majority of online interactive UPS, control its load in the 30% ~ 60% rated output power is the best way to work.
3.Prohibit frequent shutdown and open UPS power supply. General requirements in the closed UPS power supply, wait at least 6 seconds to open the power supply of UPS, otherwise, UPS power may “boot failure”, that is the state without city power output and the inverter output.
4.When using UPS power supply, be sure to comply with the relevant provisions of the manufacturer’s product specification, to ensure that the firewire, zero line, ground wire meet the requirements, users are not allowed to change their mutual order. For example, the United States a brand UPS AC power input wiring and Chinese AC input socket connection is exactly the opposite. For example, the three-phase UPS need to pay attention to the problem of phase order, otherwise there will be a phase error alarm, and so are other brands.
5.UPS power should avoid direct sunlight, and leave enough ventilation space, at the same time, prohibit the UPS output port with inductive load.
6.Strictly in accordance with the correct boot, shutdown sequence for avoiding sudden load or sudden reduction, UPS power supply voltage output fluctuations, so that UPS power supply can not work properly.

The telecom power inverter is a kind of device which can make a constant current in the circuit. The telecom inverter has positive and negative electrodes, the potential of the positive electrode is high, and the potential of the negative electrode is low; When the two electrodes and the circuit connected, telecom inverter can maintain a constant potential difference between two electrodes, thereby forming the anode to cathode by constant current in the external circuit.

The application range of telecom inverter: telecom station solar hybrid system for large power plant, hydroelectric power plant, EHV substation, unattended substation as control, signal, protection and automatic reclosing operation, emergency lighting, DC, closing all DC operating mechanism, the two loop instrument, AC DC power supply control automation the uninterruptible power supply device and electric device.

Telecom inverter working principle: telecom inverter consists of charging panel, power distribution panel, battery and DC voltage converter. The charging panel is composed of a plurality of charger power supply module and computer monitoring system, the single cabinet maximum configuration 160A, if you need a larger output current can achieve multi cabinet in parallel.
