Agilent/Keysight 400EL

The Agilent/Keysight 400EL is a four-channel DC power supply delivering 400 W total output with independent channel control for testing, development, and manufacturing applications. Each channel provides up to 32 V and 10 A, with 160 W per-channel maximum. Series and parallel configurations extend capability to 128 V maximum or 40 A maximum respectively.

The supply accepts 115 V or 230 V AC input (50–400 Hz), and features a compact 1U form factor suitable for bench and rack integration.
