Agilent 6684A 4.8 kW Programmable DC Power Supply 40 V / 120 A

The pre-owned Agilent 6684A delivers up to 40 V at 120 A—4.8 kW of clean, tightly regulated DC—in a 6-U rack chassis aimed at high-current ATE systems, battery-cycling rigs and automotive ECU development. Autoranging CV/CC output, millivolt-level programming resolution and sub-3 mV ripple keep precision analogue and RF bias rails rock-steady, while 10 ms SCPI processing over GPIB or front-panel analogue control accelerates production throughput. Remote-sense terminals cancel lead losses, and comprehensive OVP/OCP plus over-temperature protection safeguard both DUTs and cabling.

Refurbished units ship ISO-17025-calibrated with the latest firmware, providing Keysight-grade reliability, full manual/driver support and significant capital savings compared with new hardware.

Industry Background & Resource Sourcing

Over the past two decades, rapid advances in China’s radio-frequency sector have shortened production-line refresh cycles to roughly 3–5 years. Leveraging long-term partnerships with equipment OEMs, research institutes, and calibration labs, TESTRO acquires traceable, well-maintained decommissioned or replacement units. Every instrument undergoes a five-step technical check and third-party calibration before entering stock, ensuring reliable performance data.
