The Protek 3032B is a dual-output benchtop linear DC power supply engineered for electronics testing, experimentation, and repair. Each independent channel delivers 0 to ±30V DC at 0 to ±3A, with 180W total power capacity. The unit operates in constant voltage (CV) and constant current (CC) modes with automatic crossover, featuring exceptional line and load regulation, sub-millivolt ripple, and front-panel mode and overload indication via LEDs.
