N692 High Power Programmable DC Electronic Load

N692 uses a modular 3U/19-inch architecture for high-density power loading and scalable high-current or high-voltage test systems. The N692 current range extends up to 2500 A by model. Programmable dynamic load mode and arbitrary waveform loading are supported on the N692.

Where the limit actually falls on a high-power load

On a 60 kW N692 load the binding constraint is rarely the power figure: steady-state absorption, the 150 V to 2400 V class ceiling and the current ceiling of up to 2500 A all apply at the same operating point, and the lowest of the three decides what is achievable. Where the test is a converter’s transient response rather than its steady draw, the 30 kHz dynamic mode and the 500 kHz sampling of the dynamic frequency sweep are what has to be sized, and at currents approaching 2500 A the inductance of the load cabling limits the achievable current slew regardless of the load’s own bandwidth. Because a 3U chassis carries up to 6 kW, a requirement far above that figure is a rack-height, busbar and floor-loading question before it is an instrument question.

Ordering and integration notes

Options on the N692 are ordered rather than enabled: DCIR, ESR-related workflows and GPIB are all listed as optional, while LAN, RS232, CAN, USB host, digital I/O and analog I/O are standard - and the analog and digital I/O are the pair that matter when the load has to take a start signal from a PLC inside an automated test cabinet. Plan the room’s air handling and exhaust path against the full absorbed power, and confirm for the chosen model whether that energy is returned to the grid or dissipated locally. The N692 range begins at 2 kW and 150 V, so a DUT comfortably below that is better served by a benchtop load than by a rack chassis and its facility connection.
