PCU-Series High-Current DC Power Supplies

Compact high-current DC supplies for low-voltage, high-amperage work. The PCU delivers a 50 V output, with a 30 V variant, at currents from 100 A to 340 A from a 400 V three-phase input. Control runs from a 0 to 10 V analog interface with an RS422 digital interface for automated and remote operation.

1Overview

Preliminary. Specifications pending verification against the published BNC datasheet. The figures on this page are drawn from the product page summary; no detailed datasheet was available at the time of writing. Do not quote these values without confirmation.

The PCU series is a high-current DC power supply from the Berkeley Nucleonics Directed Energy Division, built for low-voltage, high-amperage applications. It pairs a 50 V output (a 30 V variant is offered) with output currents in the 100 A to 340 A range, fed from a 400 V three-phase input. The design targets continuous high-current work where a stable, controllable DC source is the requirement.

Operation runs from a 0 to 10 V analog control interface for set-point adjustment and monitoring, with an RS422 digital interface for remote and automated control. The combination suits both bench operation and integration into a larger automated test or process system.

The values below summarize the PCU from the product page. All entries are preliminary and require confirmation against the published BNC datasheet.

ParameterSpecification
Output voltage50 V (30 V variant available) (verify)
Output current100 A to 340 A (verify)
Input400 V, three-phase (verify)
Analog control interface0 to 10 V (verify)
Digital interfaceRS422 (verify)
Note. No additional ripple, regulation, stability, or dimensional figures are published on the product page. Those values are available on request and will be confirmed against the full datasheet. No numbers beyond the table above should be assumed.

3Control & Interfaces

The PCU offers two control paths. The 0 to 10 V analog interface sets the output and provides monitoring in the same convention used across the Directed Energy Division high-current supplies. The RS422 digital interface adds remote and automated control for integration into test racks and process systems. Confirm the full pin assignment, monitor outputs, and command set against the published datasheet.

4Protection & Safety

Protection and safety features for the PCU are not detailed on the product page. Confirm short-circuit behavior, thermal protection, interlock provisions, and discharge handling against the published BNC datasheet before specifying the unit for a given installation.

Verify. Protection ratings are not published on the product page and must be confirmed for each application.

5Applications

The PCU suits low-voltage, high-current DC work, including:

  • High-current component and equipment test
  • Process and production loads requiring sustained high amperage
  • Automated test integration through the RS422 digital interface

For precision magnet and EMC-sensitive high-current work, also consider the linear-regulated PTN-Series. For programmable benchtop high-voltage DC, see the PVP-Series.

6Ordering Information

Specify the output voltage variant (50 V or 30 V) and the required output current. Confirm the configuration, options, and full specifications with Berkeley Nucleonics, since detailed datasheet figures are pending.

Preliminary. Specifications pending verification against the published BNC datasheet. No specification values beyond output voltage, output current, input, and the two control interfaces are confirmed.
