Product characteristics
The inverter power supply (also called the inverter) uses the SPWM and the CPU control technology, and the main circuit uses the imported power module.12V / 24V / 48V / 110V / 220V DC power supply into 220V, 50Hz voltage stabilization, frequency stabilization, low noise, pure sine wave AC power supply.
With the rapid development of information network technology, sine wave inverter power as a new generation of DC / AC conversion power has been widely used in telecommunications, mobile, Unicom, aerospace, railway, financial management, office automation, industrial automatic control, medical and health, military research and other fields. Sine wave inverter power using battery dc as an input, after the inverter output pure sine wave ac, output voltage and frequency and is very stable and work continuously for a long time, eliminate the direct use of mains power supply interruption, voltage instability, noise interference and lightning intrusion adverse factors, at the same time overcome the small UPS power supply time short defects, to ensure continuous and reliable electrical equipment. Equipped with sine-wave inverter power supply is the best guarantee for the safe and reliable operation of the system.

Application place
The inverter power supply designed for the post and telecommunications industry is suitable for program-controlled switches, computer room, network, billing server and lighting places with 48V (or-48V) DC power (DC screen).
The inverter power supply designed for the power industry, input DC voltage is 110V / 220VDC, output is 220VAC / 50Hz pure sine wave AC power supply, mainly used in power plants, power system, railway and other important places.
The main characteristics of the high-frequency inverter power supply
◆ Compound protection mode of software protection and hardware protection, with high reliability.
◆ With perfect protection functions: input polarity reverse connection, input overvoltage, output overvoltage, overcurrent, short circuit, overheating in the machine, and other soft start function.
◆ Using three composite filter and magnetic shielding, to reduce the noise voltage of the input, excellent electromagnetic compatibility.
◆ Intelligent fan speed control system.
◆ Can be connected to pure perceptual load (to reduced use).
◆ Small volume, light weight, high efficiency, simple operation, no pollution.
Main characteristics of power frequency inverter power supply
Power frequency inverter power supply is a new type of inverter power supply designed by using advanced high frequency pulse width modulation technology and microcomputer control technology. It has the advantages of high reliability, full protection function and small waveform distortion.
It is a 220V DC into AC 220V / 50Hz, voltage stabilization, frequency stabilization, low noise. The product has a high conversion efficiency (up to 80% under full load state). There is also a strong non-linear load driving capacity. This series of inverter power supply can also monitor the input voltage, current and output voltage, current, so as to realize unattended.
◆ Adopt advanced SPWM and CPU control technology;
◆ High reliability, input and output isolation, safety and efficiency, small waveform distortion and other advantages;
◆ With the perfect protection function:
1. Output overload protection; input reverse connection protection;
2. Output overvoltage protection; input lowvoltage protection;
3. Output short-circuit protection; input overvoltage protection;
◆ Automatic bypass and uninterrupted conversion, to achieve the continuous work of the equipment.
◆ Can be used in a relatively harsh environment, with strong stability and high reliability.
◆ Has a strong nonlinear load drive capacity, can make high-power power supply.
