Kikusui PMC18-5A

The Kikusui PMC18-5A is a single-output programmable DC power supply engineered for benchtop development, testing, and quality control applications. This 90 W unit delivers 0–18 V and 0–5 A with series-regulated design, providing exceptional output stability and low ripple and noise performance. Its dual constant-voltage/constant-current operating modes with automatic crossover accommodate diverse load conditions. Analog remote control, remote sensing, and computer control via GPIB (with optional controller) enable integration into automated test systems. Parallel master-slave and one-control operation allows capacity expansion for higher power requirements.
