The JJW series voltage and current stabilizing power supply is developed using the world's advanced "floating superposition" technology. The circuit consists of transformer voltage reduction, rectification and filtering, high-power transistor adjustment, and reference sampling amplification. Dual power supplies can output independently or be used in series or parallel. When connected in series, the output voltage of the slave circuit tracks the output voltage of the main circuit. When connected in parallel, the larger output current can reach the sum of two independent output currents.
