Because it is very easy to install, thesteel bar truss deckscan save about 70% of the labor cost. It is the first choice for high-rise and super high-rise buildings.
Low-frequency inverters have a few advantages compared to higher frequency inverters; namely their peak power capacity and their reliability. Low-frequency power inverters can operate at a peak power level of up to 300% of their nominal power level for several seconds, while high-frequency inverters can operate at 200% of nominal power for a fraction of a second. Low frequency inverters operate using transformers (as opposed to electronic components such as MOSFETs for high frequency inverters). This results in a stronger, sturdier inverter which is less prone to damage.
Automatic operation and optional water level switch to prevent overflow and dry running. Full aluminum alloy shell with IP52 protection grade. Large range of ambient temperature from -20 to +60℃.
Solar pump inverter obtains direct current energy from photovoltaic cells, and converts it into electric energy to drive the water pump. According to the intensity of sunlight, take use of MPPT algorithm, the solar pump inverter adjusts the output frequency to make maximum use of solar energy.
INTRODUCTION
solar air conditioners operate directly using solar energy and utility energy , no need battery.When the sun is shining, it is powered by the solar source completely; when the sun is weak, it is powered by the solar and utility together,the whole system with hybrid design,can work online sharing with solar and utility energy.
Application:
Areas without electricity, low power,unstable power grids,and high electricity prices where air conditioner is in demand.
Medical gypsum bandage contains polyester and cotton material, medical polymer bandage: diversified specifications, suitable for different parts, and very convenient to use.
