(1) This DC regulated power supply allows for continuous adjustment of the output voltage within the range of 0 to 30V. The JA3215-OS-A04 is equipped with both coarse and fine adjustment knobs, with the initial adjustment being coarse followed by fine. Before connecting the power supply to the load circuit, it is essential to determine and accurately set the output voltage size; otherwise, over-adjusting the voltage can quickly damage the load circuit.

(2) The output of the DC regulated power supply has two wires, one positive (indicated by a red wire) and one negative (indicated by a black wire), and these two wires cannot be interchanged. When connecting the output wires of the DC regulated power supply, it is crucial to first identify the positive and negative power terminals in the circuit; they must not be reversed, as this can damage the circuit.
After connecting to the DC stabilized power supply, do not touch the two leads at the output terminal. Otherwise, a short circuit at the output terminal will occur, causing the DC stabilized power supply to enter protection mode, at which point there will be no DC voltage output (the power supply can resume normal output after pressing the reset switch once). 36V Avionics Power Supply
(4) For convenience, it is common to connect the positive and negative output leads of a DC regulated power supply with a red and black clip, respectively. The black clip (ground) is clamped onto the circuit's ground line, while the red clip is attached to the positive terminal of the power supply in the circuit. This setup is very easy to use. Additionally, it is recommended to cover the clips with insulating sleeves to prevent short-circuiting of the DC regulated power supply output if they come into contact with each other.
(5) On some DC voltage regulators, a DC ammeter is installed, which can simultaneously indicate the current output of the DC stabilized voltage. This is very convenient for maintenance. If such a current meter is not available, a DC ammeter can be connected in series with the output circuit of the DC voltage regulator.
During the maintenance of the OCL power amplifier circuit, a DC regulated power supply with dual output is required, as this type of power amplifier circuit needs symmetrical positive and negative power supply. Some other circuits also use symmetrical positive and negative power supplies.
In a regulated power supply capable of outputting two sets of DC voltages, the two circuits are independent, and the voltage adjustments for the outputs must be made separately. 400HZ power supply
