The instrument is a new generation of microcomputer controller for the new air-cool dry transformer. The core of it is a microprocessor combined with the most updated digital storage technology, which makes its performance greatly improved. Compared with the traditional design of temperature controller, this new product is a more compact one with much less components, which greatly enhanced its stabilities.

• The temperature can be easily set by the keys on the control panel and the parameters will never be lost even after power failure.
• The instrument has the “black box” function which can record the temperature of the three coils of motor at the moment of power failure.
• This instrument has had special design both in hardware and software for anti-interference. It also has the good features of operation, installation and maintenance.
• All the specifications have met the requirements of JB/T7631-2005 standards. The production line for the products has passed the certified of ISO9001.
• The products have been granted as national key-new products by China Committee of Science & Technology and China Committee of Economics & Trading in 1997.
