DC control power supply for aquaculture equipment

Abstract

The invention relates to a direct current control power supply for aquaculture equipment. It includes a switching power supply and a DC controller, which is characterized in that the switching power supply and the DC controller are sealed in the same cylindrical shell, and the switching power supply includes at least two single-chip power supply circuit boards in series, that is, the first circuit board and the second circuit board. Two circuit boards, the DC controller includes a third circuit board fixed on the inner side of the upper cover plate of the cylindrical shell. The first circuit board and the second circuit board connected in series solve the high-power bottleneck of the DC power supply device, which greatly reduces the manufacturing cost of the power supply; the use of setting it in the same cylindrical shell as the DC controller greatly increases the controller. Heat dissipation space; the combination of switching power supply and controller solves the unstable factors caused by the current limit of the wire, and also solves the problem that the machine cannot work normally due to low voltage.

Description

technical field [0001] The invention relates to a direct current control power supply for aquaculture equipment. Background technique [0002] Most aquaculture equipment uses AC motors, which need to use three-phase industrial power. It is difficult to guarantee the power supply for field operations in my country, and industrial power lines need to be approved, which virtually increases the cost of equipment use; and AC motors are used in field operations with frequent voltage drops. It is easy to burn out and seriously affect normal production. [0003] Therefore, some aquaculture equipment using DC motors appeared in the market. Compared with AC motors, DC motors have higher torque and energy efficiency, and are very popular among users. However, commercially available DC motor aquaculture equipment still has the following disadvantages and under: [0004] 1. The switching power supply and controller of the DC motor are easily damaged. First of all, due to the large spac...
