Yudian instruments are strictly controlled on temperature drift. The measurement temperature drift of AI-7/8 series high performance energy saving instrument Is less than 30ppm/oC, far lower than the market standard. Low temperature drift not only improves the product quality, but also reduces power consumption. For example, where one customer has a heating device that can normally operate under 200 -220oC, the use of low-precision instruments set at 210 oC with the drift of +/- 10 is reluctant to satisfy the production specifications, while YUDIAN instrument can stabilize temperature interval under 201 oC with a drift of +/- 1 oC, reducing the heating temperature from 210 oC to 220 oC resulting in power saving calculated to about 5% of the electric bill.

Using S thermocouple or Pt100 RTD, the measurement will be more stable rather than K or J-type thermocouple is used. Better insulating materials and lower set value (SV) as possible with consideration of manufacturing practice will also save energy effectively

AI series instruments and industrial control modules are designed with a service life of more than 10 years, with 3-year free repair within the warranty period. An easily replicable modular design and one billion times rewritable FRAM extends the service life of the products, effectively reducing the occurrence of electronic garbage, as well as the cost generated by replacing faulty and low performance instruments.

A series of protection functions such as surge protection at power up and 380VAC protection reduces the failure rates occurred. At present, annual return rate inclusive of user installation related issues are lower than 0.5%, reducing both the usage cost and waste due to the destruction of disabled instruments.

The use of high-efficiency switching mode power supply greatly reduces the power consumption, and adaptation of super-luminance LED display reduces power consumption by half. In zero output, the consumption is only around 0.5W, far below the competing products.

Energy saving relay module use high currents only at the beginning of the engaging action, compared with the engaged status being reduced to 50%. This smart technology enables the power consumption to be reduced from 0.2~0.4W to 0.1~0.2W.

Newly-designed G1 module uses 5V/30mA signal to drive SSR while standard G module uses 12V/30mA. G1 can reduce also with 0.1~0.2W the overall power consumption.

In integrated applications, AI instruments can decrease about 2W of power consumption in comparison with other similar products, not only saving energy but also reducing the temperature rise of instruments while increasing the maximum service temperature and reducing the measurement temperature drift. Calculated by service life of 10 years, each instrument can save 175 kilowatt-hour electricity. For a factory with 1000 sets, accumulative saving can be estimated to more than RMB 100,000.
