Agilent/Keysight E3645A

The Agilent/Keysight E3645A is an 80W single-output programmable DC power supply engineered for benchtop testing, R&D, and production environments. Dual-range output flexibility delivers 0–35 Vdc at 0–2.2A or 0–60 Vdc at 0–1.3A. The unit maintains tight voltage programming accuracy of ±(0.05% of output + 10 mV) and current accuracy of ±(0.2% of output + 10 mA) at 25°C ±5°C.
