Kenwood PS20-18

The Kenwood PS20-18 is a variable switching power supply delivering stable, regulated DC output across laboratory, testing, and development environments. This constant voltage/constant current (CV/CC) unit operates at 0–20 V DC with a maximum output current of 18 A and 360 W rated power. Its compact, lightweight design incorporates advanced switching topology and digital LED displays for real-time voltage and current monitoring. Comprehensive protection includes output over-voltage protection (OVP) at ~110% rated voltage, over-current protection (OCP) at ~110–130% rated current, over-heat protection (OHP) at ~100±5°C, and input power abnormality detection with fail-safe shutdown. Remote voltage sensing, external voltage control, and external current control enable flexible integration into automated test systems. The unit accepts 120 or 220/240 VAC input (50/60 Hz) and features input surge current reduction and alarm signaling for power faults.
