Agilent/Keysight 6614C DC Power Supply

The Keysight 6614C is a 50 W single-output DC power supply engineered for precision voltage and current control in automated testing and sensitive circuit development. This half-rack instrument delivers 0–100 V at 0–0.5 A with programming accuracy of ±50 mV (voltage) and ±0.05% + 0.5 mA (current) at 25°C ±5°C. Ultra-low output noise - 0.5 mV RMS and 5 mV peak-to-peak across 20 Hz to 20 MHz - makes it suitable for low-noise applications.

Fast transient response recovers within 0.1% of programmed voltage in under 100 µs, while settling time reaches within 1 LSB in less than 6 ms.
