Tanfon's Low frequency Inverter power supply is a new generation of intelligent dedicated inverter power supply ,it have been designed and developed specifically for the requirements of communication systems, railway systems, solar energy systems to meet the high quality and high reliability requirements of power supply for solar power system, railway, and power applications. And apply to all the power supply interference sensitive, need reliable, clean uninterrupted sine wave AC output system.Tanfon's Inverter power supply is a new generation of intelligent dedicated inverter power supply ,it have been designed and developed specifically for the requirements of communication systems, railway systems, solar energy systems to meet the high quality and high reliability requirements of power supply for solar power system, railway, and power applications. And apply to all the power supply interference sensitive, need reliable, clean uninterrupted sine wave AC output system.

Tanfon's Low frequency inverter power supply uses a bidirectional digital DSP as the core of the distributed system,  provide full range monitor and control for the inverter module, the AC charging module control, DC input, rectifier module, battery pack and static SCR switching. So that can improve the inverter operating efficiency and reaction speed, reduce the failure rate. That is the reason that our inverter have long service life, low overall operating failure rate, and high efficiency.Compared with other manufacturers,they use analog operating circuits and ordinary single-chip circuits.

Tanfon's Low frequency inverter power supply charging system adopts rectifier thyristor type charging. Battery voltage,charge and discharge current management and strict control are the key to protect the battery and extend the service life of the battery. The charging mode and charging current of the rectifier module are adjusted,it automatically complete battery management and maintenance! It is more advanced and easier to manage and maintain than another company which use charging circuit board. Our charging current can reach up to 50A, while the another company's charging circuit board can only reach about 5A, and our thyristor charging can use the city power input range wider to reach 25%.

Other manufacturers use relay switching has the problem of power off, and the relay has a high failure rate.

Our Low frequency inverter have the switching function between the utility power and the battery,or the automatic switching of the mains and low-voltage devices after the battery is reversed is controlled by a digital DSP,so it is automatic switching, automatic charging, switching time is 0second, and reducing the damage to the equipment used by the power failure.

Our Low frequency inverter have adaptive generator function, with generator input adaptation function, can track and memorize the input frequency, adopt all-digital vector control technology of DSP, MCU and DDC real-time processing, make the input frequency range of the inverter reach 44Hz-66Hz, Output 50Hz or 60Hz, can send starting input signal to the generator,make the generator start automatically.Other manufacturers have low adaptability of the generator, the impact or unstable frequency will cause the inverter automatically report the fault and stop output, IGBT damage and so on.

company adopts mains input reactor, DC input high-frequency low-impedance electrolytic capacitor and all-digital IGBT absorption board, feedback drive board to ease power surge, high-voltage spike, transient high-voltage interference, voltage sags, frequency deviation, flash Variation, voltage imbalance, harmonic distortion, continuous undervoltage or overvoltage, system ground fault, and safety fault due to leakage current. It is more stable than the simple absorption capacitors used by other manufacturers, and has the lowest damage to the equipment.
