Abstract

The invention provides a multichannel constant voltage source which comprises a shell. A circuit board is arranged in the shell, an alternating-current input interface is integrated on the circuit board, alternating current passes the alternating-current input interface and then is sequentially connected with a full-bridge filter shaping module, a voltage adjusting distribution module and an isolation driving module, direct-current high voltage is outputted by an inverter output execution module, the voltage adjusting distribution module, an ARM (advanced RISC machines) main control module and an SPWM (sine pulse width modulation) wave generation module form a control loop, the inverter output execution module is further connected with the ARM main control module through a signal acquisition feedback module, and the ARM main control module is further connected with the full-bridge filter shaping module through a brake shutoff contact and electrically connected with an energy storage device, a temperature detection unit, an alarm unit and a lighting unit. The constant voltage source is low in design cost, less in wiring, more convenient to produce and maintain, high in efficiency, simple in structure, convenient to operate, high in accuracy and small in occupied space.

Description

technical field [0001] The invention belongs to the field of electric equipment, and in particular relates to a multi-channel voltage stabilizing source. Background technique [0002] As a multi-purpose power supply, the regulated power supply can provide users with multiple frequency outputs through the energy conversion of the mains power supply. The voltage is continuously adjustable, providing a wide output voltage adjustment range of 10-450V, and the waveform distortion can reach 1.5%. It is also equipped with an intelligent color LED digital display screen to provide users with a multi-channel composite mode digital display solution, including: output frequency, channel characters, current channel voltage effective value, current effective value, active power and units of various parameters, The voltage and current are both 41 / 2 accuracy, and the highlighted characters can be displayed clearly even in sunlight. However, the existing regulated power supply cannot provi...
