For technical questions on bidirectional, regenerative and programmable DC power supplies, or for product specifications and quotations on the reference platform, here is how to reach the engineering team.

Engineering and product enquiries

The instrument family referenced throughout this resource, the N35500 series, is built by Ultra Power Systems. For application advice, detailed specifications, configuration help or a quotation, contact their engineering team directly:

When you write, it helps to include your application (battery test, PV inverter test, energy-storage / PCS test, or general ATE), the voltage and power range you need, and which control interface (SCPI, Modbus-RTU or CANopen) your test system uses. That lets the team scope a configuration in one reply instead of several.

Which questions go where

To get a useful answer quickly:

How does it work? The articles on this site cover four-quadrant operation, regenerative recovery, battery emulation, PV simulation and SCPI automation. Start there and follow the related links.
What are the exact specs / is there a model for my range? Ask the manufacturer at Ultra Power Systems; specifications and availability come from them, not from this resource.
I need a quotation. Quotes are handled by Ultra Power Systems on a per-configuration basis, since high-power bidirectional supplies are usually specified to the application.

Information to include in a technical enquiry

For an application or specification question, a short, structured message gets a precise answer fastest. Useful details to include:

Application and standard. What you are testing (cell, module or pack, PV inverter, BESS / PCS, generic ATE) and any standard you must meet, for example EN 50530 or IEEE 1547.
Electrical envelope. Voltage range, current and power, and whether you need sink (regenerative) capability or full four-quadrant operation.
Accuracy and dynamics. Required full-scale accuracy, readback resolution and the response time your transient or MPPT profiles demand.
Control and integration. Your preferred interface (LAN, RS-232, RS-485 or CAN) and protocol (SCPI, Modbus-RTU or CANopen), plus the test framework it must talk to.

With that in hand, the team can map your requirement onto a configuration in a single exchange.

About this resource

dcpowersupply.net is an independent technical reference and does not process orders or hold inventory. We maintain the explanatory content and keep it aligned with the referenced standards (EN 50530, IEEE 1547, IEC 61010, ISO 17025) and with the N35500 platform used in our examples. For anything commercial, the links above route you to the manufacturer.

Frequently asked questions

How do I request a quotation for a DC power supply?

Email the manufacturer at Ultra Power Systems with your application, required voltage and power range, and control interface. Because high-power bidirectional supplies are configured to the application, quotes are issued per configuration rather than from a fixed price list.

Can this site answer detailed product specification questions?

For conceptual and standards questions, yes, the articles here cover the methods and definitions. For exact model specifications, options and availability, those come directly from Ultra Power Systems at Ultra Power Systems.

Specifying a bidirectional DC supply?

The articles here describe the N35500 platform from Ultra Power Systems.
