HP / Agilent 6612B DC Power Supply, 20Vdc, 2A

The HP/Agilent 6612B is a programmable DC power supply delivering 0–20 Vdc at 0–2 Adc (40 W) for automated test systems, R&D, and production environments. This half-rack instrument combines precise voltage and current control with fast transient response, built-in measurement capability, and comprehensive protection. Programming accuracy reaches 0.05% + 10 mV for voltage and 0.05% + 1 mA for current. Measurement accuracy via HP-IB or front panel spans 0.03% + 3 mV for voltage, with dual-range current measurement down to ±2.5 µA. Output voltage recovers within 0.1% of rated value in less than 100 µs following a 50% load step. Command processing initiates within 4 ms average, with full settling in under 6 ms (2 ms in fast mode). Load regulation holds voltage to ±2 mV and current to ±0.5 mA maximum. Line regulation maintains ±0.5 mV voltage and ±0.5 mA current stability. Ripple and noise measure 0.5 mV rms / 3 mV peak-peak (voltage) and 1 mA rms (current) across 20 Hz to 20 MHz. Fixed 1 A sink current capability enables bidirectional output operation.
