Keysight (Agilent) N8937A

The Keysight N8937A is a programmable DC power supply delivering up to 15 kW of output power for automated test equipment and precision power delivery applications. Its autoranging architecture provides voltage and current combinations across the full 0–1500 V, 0–30 A operating range at maximum power - effectively consolidating multiple traditional supplies into a single unit. Up to ten units operate in parallel with built-in master/slave control, enabling scalable output current and combined power exceeding 100 kW without individual unit programming.
