HP / Agilent 6205C Dual-output power supply, 0-20 VDC or 0-40 VDC

The HP/Agilent 6205C is a dual-output regulated power supply delivering two independent, electronically controlled channels with selectable voltage ranges and integrated current limiting. Each output operates at 0–20 VDC / 0.6 A or 0–40 VDC / 0.3 A, accommodating diverse test requirements across electronics development, circuit characterization, and laboratory bench work. Precision 10-turn voltage controls enable fine adjustment, while integrated volt/ampere metering and front/rear accessible terminals support both local operation and remote programming via resistance or voltage control. Load regulation holds within 0.01% + 4 mV and line regulation within 0.01% + 4 mV across the full input range. Output noise remains below 200 µVrms, with temperature stability of 0.02% + 1 mV/°C and long-term drift under 0.10% + 5 mV after warm-up. Remote sensing provisions and adjustable current limiting on each section support demanding test scenarios. The unit accepts 115 VAC ±10% or 230 VAC ±10% at 48–440 Hz, drawing 31 W at full load, and operates via convection cooling without active ventilation.
