Recently, we entrusted CQCTT, an industry authority, to conduct the IEC62109 standard test on two kinds of our products, solar tracker controller (TCU) and intelligent communication unit (NCU). Passing the test of this standard means that products possess high stability and reliability, and have reached the international leading level.


During the test, TCU controller works together with NCU communication unit and motor. After the NCU communication unit and TCU controller are connected, the normal operation of the motor is used to determine whether the whole system is running normally. The test projects include Clearance and Creepage, electrical strength text, impact pressure test, contact current test, etc. The conclusion is passed.
