SPWR-BAY Private Enterprise is a manufacturer of power supply devices and converting equipment (AC / DC, DC / DC, DC / AC, UPS) of the SPWR brand: power supplies for electronic equipment (secondary power sources, with output voltages. 12V; 13.8V; 24V; 27V; 28V; 30V; 32V; 36V; 48V; 50V; 60V; etc.); power supply installations; inverters for converting and stabilizing the voltage generated by wind energy (wind generator) plants and systems; rectifier blocks; guaranteed power supply installations; uninterruptible power supplies (for various purposes, including for automatic telephone exchanges 48V, 60V); automatic chargers; laboratory power supplies; special regulated power supplies; inverters (voltage and frequency converters) for energy, telephone exchanges, rail, road and sea (river) vehicles (24,48,50,60,96,110,220VDC in 220VAC).
Almost all the power sources presented on the company's website have a PFC system (Power Factor Correction - Active Power Factor Corrector). PFC is designed to reduce the power consumption of the reactive power supply. PFC-free power supplies create high power line disturbances for parallel connected appliances.
The company has developed new inverters with the possibility of parallel connection of the output without a control module (for example, connecting 5 inverters PN 110 (48.60,220) V / 220V 5kVA gives total power with a coefficient of 0.9 - 22.5kVA). PN series inverters have a pure sine wave of the output current at the output.
Among the manufactured inverters (voltage converters) by various companies, there are several groups that differ in cost by about 15 times. The first group of more expensive inverters provides a sinusoidal output voltage. The second group provides the output voltage of a simplified form, replacing a sinusoid. The most commonly used signal is a trapezoidal sine
For the vast majority of household appliances, it is permissible to use alternating voltage with a simplified waveform. The sine wave is important for industrial, telecommunications, measuring, laboratory devices, medical equipment. The inverter is selected based on the peak power consumption of a standard voltage of 220V / 50Hz.
There are three inverter operation modes. The continuous operation mode corresponds to the rated power of the inverter. Overload mode: in this mode, inverters can give power 1.5-1.7 times the rated power for some time. Strong short-term overload occurs, for example, when you turn on the compressor of the refrigerator. In the “Start” mode, the inverter is capable of delivering increased instantaneous power within a few milliseconds, to ensure the launch of electric motors and capacitive loads.
The SPWR-BAY company offers inverters (voltage converters) for industrial use for demanding equipment to the quality of the power supply network parameters, SPWR inverters are successfully used in telecommunications, energy, railways (rolling stock), and aviation.
