The HP E3632A is a single output, dual range programmable dc power supplies designed to deliver reliable and high quality operation. 0.01% load and line regulation keep the output steady. The linear supply specifies both normal-mode voltage noise and common-mode current noise. The low normal-mode specification assures clean power for precision circuitry and the low common-mode current provides isolation from power line current injection. Both voltage and current can be monitored simultaneously for output from the front panel on an easy-to-read vacuum fluorescent display. A knob allows you to set the output at the resolution you need for the most exacting adjustments, quickly and easily. Store and recall key enables you to save and recall up to three frequently-used states. The output on/off button enables/disables the output. All the outputs are isolated from the chassis ground and from the remote interface. Specifications. DC Output Low Range/High Range: 0 to 15 V, 7A / 0 to 30 V, 4 A. Load and line regulation Voltage: < 0.01% + 2 mV. Load and line regulation Current: < 0.01% + 250 µA. Ripple and noise (20 Hz to 20 MHz) Normal-mode: < 350 µV rms / 2 mV p-p (Voltage), < 2 mA rms (Current). Ripple and noise (20 Hz to 20 MHz) Common-mode Current: <1.5 µA rms. Programming accuracy (25° C ±5° C): 0.05% + 10 mV (Voltage), 0.2% +10 mA (Current). Readback accuracy (25° C ±5° C): 0.05% + 5 mV (Voltage), 0.15% +5 mA (Current). Resolution Program/readback: 1 mV, 0.5 mA / 0.5 mV, 0.1 mA. Resolution Meter: 1 mV / 1 mA. Transient Response Time: 50 µsec for output to recover to within 15 mV following a change in output current from full load to half load or vice versa. GPIB/RS-232 standard.
