The YOKOGAWA HP P/N 0950-2211 Power Supply delivers stable, regulated power for precision measurement and control applications in industrial and laboratory environments. This module provides selectable AC input voltage configurations from 100 V to 440 V AC, with power consumption of approximately 30 VA. The unit features programmable output control with internal memory capacity for up to 50 program steps, IC memory card storage for 7 pattern programs, and IEEE 488-1978 GPIB compliance for remote instrument integration. Automatic limiter recovery protects against transient overload conditions. Response time to within ±0.1% of setpoint is less than 10 ms under maximum load with resistive termination. The compact form factor—213 mm (W) × 88 mm (H) × 350 mm (D)—mounts horizontally using the supplied fixture with M3.5 terminal connections and 1.25 mm² minimum wire gauge accommodation.
