Bidirectional DC Power Supply Price: How Quoting Works
High-power bidirectional supplies are engineered to your specification, so there is no shelf price. Here is exactly how the quote process works and what to send to get an accurate figure quickly.
Why there is no list price
A bidirectional, regenerative DC system is configured, not catalog-stocked. Two labs asking for "a 1500 V supply" can need very different machines once power, channel count, paralleling, simulation options and interfaces are settled. Pricing therefore reflects the build, the same way a server or a vehicle is priced by configuration rather than a single sticker.
This is why Ultra Power Systems quotes the N35500 platform to spec: you pay for the voltage class, power and features you actually need, with no padding for capability you will never use.
What drives the price
| Factor | Why it matters |
|---|---|
| Voltage class (up to 2250 V) | Sets the core hardware platform |
| Power (up to 42 kW/3U, MW via parallel) | Number and size of chassis |
| Channel count | Independent outputs for parallel testing |
| Simulation options (NS81000 battery, NS91000 PV) | Added firmware/capability licenses |
| Interfaces & integration | Protocol mix, ATE integration support |
| Calibration & compliance | ISO 17025-traceable cal, documentation |
Send this for a fast quote
The more of this you provide up front, the faster and more accurate the quote:
- Maximum bus voltage of your device under test (so the class is right first time).
- Continuous and peak power, and whether you need to source, sink, or both.
- Channel count and whether channels must run independently.
- Simulation needs: battery emulation, PV array emulation, or neither.
- Control environment: SCPI/LAN, Modbus, CANopen, plus any ATE you must integrate with.
- Application and standards: EV pack test, ESS/PCS, PV inverter, aerospace/ATE, and any compliance you must meet.
Not sure on power sizing? The regenerative guide helps frame duty cycle, and the voltage-class table helps pin the class.
What a good quote includes
A configured quote should do more than name a number. Expect it to spell out the exact voltage class and per-channel power, the chassis count and how units parallel to reach your total, which simulation and interface options are licensed, and the calibration and compliance documentation included. That detail is what lets you compare options on a like-for-like basis and confirm the system matches your test plan before any order is placed.
It also gives you a defensible internal justification: because the build is itemized, you can see precisely what each capability costs and trim anything outside your requirement. Quote-based purchasing is not a barrier, it is how you avoid paying for a generic over-spec'd box and instead get a system sized to the work in front of you.
