The Agilent/Keysight E3620A is a 50 W dual-output DC power supply engineered for benchtop test and development environments. It delivers two independent, isolated outputs—each capable of 0 to 25 Vdc at up to 1 A—with constant voltage and constant current operating modes. Manual 10-turn potentiometers provide precise voltage and current adjustment. Digital panel meters display simultaneous voltage and current readings with ±0.5% + 2 counts accuracy. Low output noise (0.35 mV rms typical), excellent line and load regulation (0.01% + 2 mV), and fast transient response (<50 µsec) make it suitable for sensitive analog circuits and device characterization.
