N362 Wide Range Programmable DC Power Supply

On the N362, system heat dissipation and device selection allow compact 1U and 2U rack formats while maintaining wide-range output capability. Voltage families include from low-voltage high-current models through 1500 V options for applications across electronics, automotive, aerospace, and energy systems.

Rack integration and automotive sequences

Up to 10 kW in a 2U 19-inch chassis moves the constraint in an ATE cabinet from rack units to the cabinet’s AC feed and rear airflow, which are what actually decide how many N362 units a bay will hold. On the N362, analog programming is optional and only on supported models, so an ATE design that sets the output from an analog set-point has to specify it with the order, whereas LAN, RS232, RS485 and CAN are standard: Modbus-RTU suits an RS485 production line, CANopen suits a vehicle-bus bench, and SCPI suits a scripted sequencer. If ISO16750-2 or LV124 sequences are in scope, the built-in car startup, voltage drop, load dump and reset waveforms are the reason to choose an N362 over a plain programmable source, because the alternative is an arbitrary waveform generator driving a linear amplifier.

Choosing the right family rather than the widest one

The accuracy figures on an N362 carry a full-scale term, 0.03% + 0.02% F.S. on voltage and 0.1% + 0.1% F.S. on current, so the narrowest voltage family that still covers the DUT’s maximum is the one that measures most accurately. A 1500 V model operated near the bottom of its range gives up resolution that an 80 V model near the top of its own range keeps, which is why the series is built as six discrete voltage families rather than one continuous span. CC/CV priority is a per-DUT decision rather than a default: a capacitive or battery-like load connected to a voltage-priority output draws the full programmed current limit until its terminal voltage catches up, and selecting current-loop priority is what avoids that.
