Adjust the " coarse " knob first according to the required voltage, then gradually adjust the " fine " knob to achieve proper coordination. For example, to output 12V, set the " coarse " knob to the 15V position, then adjust the " fine " knob to 12V. The " coarse " knob should not be set to the 10V position. Otherwise, the output voltage will not reach 12V.
Adjust to the required voltage before connecting the load.
During the operation of the DC regulated power supply, when it is necessary to switch to the "粗调" (粗调) setting, the load should first be disconnected. After the output voltage is adjusted to the desired value, reconnect the load.
During operation, in case of protection due to load short circuit or overload, the load should first be disconnected, then press the "Reset" button. Alternatively, you can also restart the power supply, and the voltage will return to normal operation. Reconnect the load after the fault is resolved. Power sources: 115/200V, 440Hz, 8; Aviation ground power, 15; 27V DC power.
When using various power supplies with different rated currents in series for a DC stabilized power supply, the output current is equal to the rated value of the path with the smallest rated current.
Each power line has a meter head, which indicates either the output current or voltage of the line depending on the A/V status. Typically, it is set to the voltage indication state.
Each channel features two output terminals, one red and one black. The red terminal indicates “+”, while the black terminal signifies “-”. The center of the panel has a black terminal with a "ground" symbol, which connects to the housing and is electrically isolated from each output channel, serving solely as a safety line. Many people mistakenly assume that the "ground" symbol indicates grounding, with "+" and "-" representing the positive and negative power supply lines for dual power supply operational amplifiers.
8. The two voltage sources can be used in series, but not in parallel. The power supply is a measuring instrument for supplying power, thus it is not allowed to short-circuit the output terminals for extended periods.
