Information

1.Along with the quick development of information network technology, Inverter / Power Inverter / Inverter Power Supply is a new DC to AC conversion power supply.
2.The inverter power supply is widely used in the fields such as Telecom, Mobile, Unicom, Aviation and spaceflight, finance management, OA, industrial auto control, medical treatment and sanitation, military affairs, scientific research etc.
3.Use the battery DC as input, after inverting,it will output the pure sine wave AC. The output voltage and frequency is ultra-reliable and and work continuously in long time. Inverter can eliminate the disadvantage such as power interrupt, un constant voltage, noise interfere and surge etc.
4.At the same time, Inverter can solve the limitation of short backup time of UPS. So Inverter can ensure the continually and reliable working of electro-equipments.

Character

YK-DA-HD series pure sine wave Inverter / Power Inverter / Inverter Power Supply is a new device which can invert the DC to AC, special design for the electric power system.

  • 1. Software protection and hardware protection, high reliability
  • 2. Perfect protection: input polarity reverse, input over/under voltage, over current, short circuit, over heat. Also the soft start function
  • 3. 3 Layers composite filter and magnetism shielded which and reduce the reflect noise voltage to the input port, perfect electromagnetism compatibility.
  • 4. Intelligent Fan
  • 5. Can connect with pure sensibility load (Should reduce voltage)
