The Agilent/Keysight 6525A is a high-voltage DC power supply engineered for precision applications requiring stable output at elevated voltage levels. This all-silicon instrument delivers up to 4000 V at 50 mA, featuring exceptional load and line regulation of 0.01% across both voltage and current, with ripple and noise performance of 2 mV rms. Operating in constant voltage/constant current mode with automatic crossover, the 6525A maintains tight control across varying loads and input conditions. The supply accepts 115 VAC or 230 VAC input (with Option 313) at 48–440 Hz, drawing 270 Watts at full load on 115 VAC/60 Hz at 4.0 Amperes. Optional crowbar overload protection is available. Configured for benchtop or standard 19-inch rack mounting, the 6525A serves semiconductor testing, high-voltage component characterization, and laboratory research environments where regulation stability and voltage precision are critical.
