YK-DA-WT Inverter / Power Inverter / Inverter Power Supply uses the American INTEL 16 digits micro-processor control. The main circuit of YK-DA-WT (48dc to 220ac) dc ac inverter used the imported power modules. With the strongpoints such as high reliability, perfect protection function, low waveform distortion and lower price etc. The inverter of YK-DA-WT (48dc to 220ac) dc ac inverter has high invert efficiency (in the condition of full load, the invert of YK-DA-WT (48dc to 220ac) dc ac inverter efficiency can be up to 85%). At the same time, this inverter of YK-DA-WT (48dc to 220ac) dc ac inverter have strong non liner load driving capability. Also, Inverter can control the monitor the input voltage/current, output voltage/current. Inverter can realize the function of unattended operation .

Main Characteristics
1. Adopts the advanced SPWM and CUP control technology
2. High reliability, input/output isolated, safe and high efficiency, low waveform distortion
3. Perfect protection:
4. Output overload protection
Input reverse connection protection
Output over voltage protection
Input under voltage protection
Output short circuit protection
Input over voltage protection;
5. Auto bypass switch,uninterrupted operation;
