Kepco BHK1000-0.2M

The Kepco BHK1000-0.2M is a 200 W DC power supply delivering 0–1000 V at 0–0.2 A with voltage and current stabilization and automatic crossover. Built on a hybrid architecture combining vacuum tube series control with solid-state reference and amplifier stages, this full-rack unit operates from single-phase AC input (105–126 V or 210–250 V AC, 50–65 Hz) and supports both local keypad control and remote programming via analog terminal strips or IEEE 488.2 GPIB interface. The unit features 12-bit control resolution, FET output stage, dual fusing protection (AC and DC), and operates across –20°C to +55°C ambient conditions. Output voltage displays to one decimal place; output current displays to three decimals. Selectable fast response mode disconnects output capacitance for improved transient performance in current source or rapidly programmed applications. The supply meets EN61010-1 safety requirements and carries CE certification.
