Keysight (Agilent) N8735A DC Power Supply, 30 V, 110 A, 3300 W, Programmable

The Keysight N8735A is a programmable single-output DC power supply delivering 30 V, 110 A, and 3300 W for demanding test and measurement applications. This 2U rack-mount instrument combines high power density with flexible control interfaces, enabling both manual front-panel operation and fully automated remote command via GPIB, LAN (LXI-C), or USB. The supply operates in constant voltage and constant current modes, with programming accuracy of ±0.05% + 15 mV (voltage) and ±0.1% + 220 mA (current).

Front-to-back airflow cooling permits stacking without additional overhead clearance, while built-in over-voltage, over-current, and over-temperature protection safeguard connected loads. Fifteen store/recall states preserve custom configurations, and independent remote on/off and enable/disable control streamline integration into test benches and automated test equipment racks. The unit accepts single-phase 190-240 V, 50/60 Hz input (Opt. 230) or three-phase 180-235 V, 50/60 Hz input (N8735A-208).

Up to four units may be paralleled for increased current; series connection of up to two units increases output voltage. BenchVue Basic software (node-locked) is included.
