According to the required voltage, first adjust the " coarse adjustment " knob, then gradually adjust the " fine adjustment " knob to ensure proper coordination. For example, when the output voltage required is 12V, set the " coarse adjustment " knob to the 15V position, then adjust the " fine adjustment " knob to 12V. The " coarse adjustment " knob should not be set to the 10V position. Otherwise, the output voltage will not reach 12V. Avionics Power Supply
2. Adjust to the required voltage before connecting the load.
During operation, when adjusting to the " coarse " tuning setting, the load should first be disconnected, wait until the output voltage is adjusted to the desired value, and then reconnect the load.
During operation, in case of maintenance due to load short circuit or overload, first disconnect the load, then press the "Restore" button, and also restart the power supply. The voltage will return to normal operation. Reconnect the load after the fault is cleared. 400HZ Variable Frequency Power Supply
When using different rated current power sources in series, the output current is the rated value of the path with the smallest rated current.
Each power line features a gauge that indicates either the output current or voltage of that line, depending on the A/V status. It is typically set to the voltage indication state.
Each channel features two output terminals, one red and one black. The red terminal signifies “+”, while the black terminal indicates “-”. The center of the panel has a black terminal with a “ground” symbol, indicating that this terminal is connected to the housing. It is electrically isolated from each output channel and is used solely as a safety wire. Many people mistakenly assume that the “ground” symbol indicates grounding, with “+” and “-” representing the two power supply lines entering to power the dual power supply op-amp. 400HZ power supply
