The output voltage of this DC power supply can be continuously adjusted within the range of 0 to 30V. The JA3215-OS-A04 is equipped with two adjustment knobs, a coarse and a fine one, with the coarse adjustment followed by the fine adjustment. It is crucial to determine and accurately adjust the output voltage before connecting the power supply to the load circuit; otherwise, over-adjusting the voltage can quickly damage the load circuit. Aeronautical Power Supply
The output of the DC voltage regulator has two wires, one positive (represented by a red wire) and one negative (represented by a black wire), and these two wires cannot be interchanged. When connecting the output wires of the DC voltage regulator, it is crucial to first identify the positive and negative power terminals in the circuit; they must not be reversed, as this could damage the circuit.
After connecting the DC stabilized power supply, do not let the two wires at the output terminal touch each other, otherwise the output terminal will short-circuit, causing the DC stabilized power supply to enter protection mode. At this point, no DC voltage is output (the power supply can resume normal output after pressing the reset switch once).
For ease of use, the positive and negative output leads of a DC stabilized power supply are often connected with a red and black clip, respectively. The black clip (ground wire) is clamped onto the circuit's ground line, while the red clip is attached to the positive terminal of the circuit. This setup is highly convenient. Additionally, an insulating sleeve should be placed over the clips to prevent any short circuits at the output end of the DC stabilized power supply. 36V Avionics Power Supply
On some DC stabilized power supplies, a DC ammeter is installed, which can simultaneously indicate the current output of the DC stabilized voltage. This is very convenient for maintenance. In the absence of such a current meter, a DC ammeter can be串联 in series with the output circuit of the DC stabilized power supply.
During the maintenance of the OCL power amplifier circuit, a DC regulated power supply with dual outputs is required, as this type of power amplifier circuit necessitates symmetrical positive and negative power supply. Similarly, some other circuits also employ symmetrical positive and negative power supply configurations.
In a voltage regulator power supply capable of outputting two sets of DC voltages, the two circuits are independent of each other, and the voltage adjustments must be made separately. 400Hz power supply
