Because capacitive load has the characteristics of increasing output voltage. Especially when output voltage adjusts from high voltage to low voltage, it will cause voltage fall slowly. Thus, normally, a power resistance will parallel connect to the output terminal and a diode will series connect between output terminal and load. It could reach a good application.
When change the output current, inductive load will create negative induced electromotive force. If power source could not absorb this part of energy or without adding absorption circuit in output terminal, it will damage the inductive load. APM middle power source has anti-reverse function which could perfectly solve the problem. Without adding external absorption circuit, only need to connect short circuit copper sheet in internal of power source, then output capacitance and other circuit could absorb this part of energy. This function could activate or ban accordingly.
At the meanwhile, APM high power DC source is completing the 3 stage charging function. It is easy to operate. It could transfer condition according to test data of battery.
APM high power DC source support CC&CV priority function to decided output high speed voltage model or no overshoot current. When test LED load, it could select CC priority mode to avoid overshoot of output current.
