The CV model load is the basic of the LED power supply test. CV is constant voltage, but the load is only the current load equipment, itself does not provide constant voltage, therefore, the so-called CV is just through the voltage negative feedback circuit, to servo the change of LED power supply output current, to make the LED output capacitor charge balance, thus achieve the purpose of constant...
Glow wire test is to test the stability of electrical and electronic products during working. And the hot wire itself is the resistance wire ring with fixed size. When doing test, the wire ring should be heated up to the specified temperature by electricity, so that the time when the top of the wire reached the sample can meet the time standard required, then observe and measure its state. The tes...
