Modern PCBAs use both analog and digital circuits, where each part requires different voltages to work properly. Digital chips often require +5V or +3.3V, analog circuits like op‑amps need ±15V, and power drivers or industrial modules may use ±24V. A single DC power source cannot provide all these voltages at once, which is why we use a multi‑rail regulated DC power supply. This module can deliver DC ±24V, ±15V, and ±5V stable voltages at the same time. It allows engineers to test bench circuits under real operating conditions, making prototyping safer, troubleshooting easier, and eliminating the need for multiple separate supplies.
Schematic of ±35V to multi-rail ±24V, ±15V, ±5V regulated dc power supply circuit as shown below.
