Kenwood PA18-3

The Kenwood PA18-3 is a series-regulated CV/CC (Constant Voltage/Constant Current) power supply delivering 0–18V at 0–3A with 54W output capacity. Engineered for research, development, aging, and system power supply applications, it combines low ripple (6.0 mArms, 12 mAp-p) and low noise with simultaneous digital metering. The 3½-digit LED voltmeter and 3-digit ammeter provide real-time monitoring, while green and red LED indicators distinguish between constant voltage and constant current operation modes. Temperature coefficient of 500 ppm/°C and meter accuracy of ±2.5% f.s. ensure stable, repeatable performance across operating conditions.
