Embodiment
[0015] In this embodiment, a multifunctional adjustable AC and DC power supply, such as figure 1 As shown, it includes a housing, which is composed of a casing 1 and a bottom shell 2. The bottom shell 2 includes a bottom plate 21, and a panel 22 and a rear plate 23 are vertically connected to the front and rear sides of the bottom plate. The panel and the rear plate Reinforcing plates 14 are respectively fixed between the two ends of the upper edge, and the cover is buckled on the bottom shell. An AC voltmeter 3, a DC voltmeter 4, a plurality of rubber sockets 5, and a handwheel 6 are installed on the panel, and a wire bag 8, a transformer 13, and a circuit board 15 are installed in the housing, and the wire bag passes through the rubber gasket 8, and the wire bag stands Plate 7 is mounted on the inside of the panel and the hand wheel is connected to the wire pack. The transformer is installed on one side of the line pack, and is installed side by side with the line pack. The...

The invention relates to a multifunctional adjustable AC / DC power supply, which mainly solves the problem that in the prior art, an AC / DC regulated power supply has a large volume and does not have the function of digitally displaying voltage and current. The power supply comprises a shell, wherein the shell consists of a bottom case and a cover piece; the bottom case comprises a bottom plate, and a panel and a rear plate which are arranged at the front and rear ends of the bottom plate; an AC voltmeter, a DC voltmeter, a connecting rubber socket and a regulating hand wheel are arranged on the panel; a solenoid connected with the hand wheel is arranged in the shell; one side of the solenoid is provided with a transformer connected with the AC voltmeter, the DC voltmeter and the rubber socket; a circuit board is also arranged in the shell; and the solenoid and the transformer are connected to the circuit board respectively. The multifunctional adjustable AC / DC power supply has high capacity and a small volume, simultaneously has the function of displaying the voltage and the current by a pointer, and is convenient to operate by a user.
Description
technical field [0001] The invention relates to a power supply, in particular to a multifunctional adjustable AC and DC power supply which can output stable AC and DC voltages and has the function of displaying the AC and DC voltages with pointers. Background technique [0002] The current AC and DC regulated power supplies are relatively large in size, and the installation is not compact enough. Moreover, the AC / DC regulated power supply does not have the digital display function of voltage and current. When it is used as a laboratory power supply in a school training institution, the user cannot directly read the value of the voltage and current, which is inconvenient for the user to operate. Contents of the invention [0003] The present invention mainly solves the problems of large volume and no digital display function of voltage and current in the AC / DC stabilized power supply in the prior art. Function adjustable AC and DC power supply. [0004] The above-mentione...
