Traditionally, only a passive power supply voltage and current output. The high-end equipment to ensure reliability. 
 In the maintenance. Have to be to measure the power measurement instrument auxiliary output voltage. Current. Operating temperature. Working hours. Cause efficiency and cost are a big waste. Ngong Ding intelligent memory power (digital display din rail power supply). to display the output voltage. Average current / peak current. operating temperature. a single working hours. total working time. more power alarm signal abnormalities (including voltage. current. temperature. time). truly achieve the maintenance-free user-friendly operation design .72 w.120w.200w.240w.500w.1000w Certification is complete. more prepared the source function. cheap. Ngong Ding cost the company very much like to enhance customer profitability. so that our customers and the public different.
