UDP5000 DC Switching Power Supplies

The UDP5000 line is a 20-SKU high-power programmable DC switching supply family covering 400 W to 2 kW across four output voltage classes — 40 V, 80 V, 160 V, 250 V, and 800 V — with corresponding current capability up to 200 A per output. All twenty models share an 8-inch touch display, sequence/list mode programming, and SCPI remote control over LAN, USB, and optional GPIB. The 800 V UDP5800 tier serves electric-vehicle, energy-storage, and solar-inverter bench applications.

UNI-T UDP5000 DC Power Supply — Buyer's Guide

Which UDP5000 Is Right for You?

The UDP5000 series is UNI-T's programmable switching DC power supply line, with 20 models spanning 40 V to 800 V output and 400 W to 2000 W. Every unit supports constant-voltage and constant-current operation, list sequencing, remote SCPI control, and series/parallel combining for higher voltage or current. The choice between models comes down to output voltage class first, then power level within that voltage class.

Performance, protections, and programmability are identical across the line. You're choosing for your load.

Decision 1: Choose Your Voltage Class

Pick the lowest voltage class that exceeds your maximum load voltage with reasonable headroom (typically 10–20%). Higher voltage classes trade max current at a given power rating.

40 V

Best for: Low-voltage battery (1S–10S Li-ion), 3.3 V/5 V/12 V/24 V/36 V digital systems, automotive 12 V/24 V bus testing

80 V

Best for: 48 V telecom, e-bike packs (10S–20S), light EV traction, two-wheeler battery test

160 V

Best for: Solar microinverter, 96 V industrial, 120 V mains-derived DC, mid-voltage battery test

250 V

Best for: 200 V industrial, single-phase mains DC, PV string-level test, light EV battery packs

800 V

Best for: EV traction battery (400–800 V architectures), high-voltage PV strings, industrial DC bus, fuel cell test

Decision 2: Choose Your Power Level

Within each voltage class, four power levels — 400 W, 800 W, 1200 W, and 2000 W — cover everything from low-current cell-level testing through 200 A automotive battery validation. Constant-power architecture means a 2000 W unit delivers 2000 W across most of its V/I envelope, not only at maximum voltage.

Power Level	Form Factor	Typical Use
400 W	2U benchtop	R&D bench, cell-level battery test, embedded systems, prototyping
800 W	2U benchtop	Module-level battery test, light power-electronics validation, ATE
1200 W	3U / rack	Pack-level battery test, mid-power converter validation, production test
2000 W	3U / rack	EV pack test, high-current motor drive, industrial production test

Tip: Need more power than 2000 W? Use parallel mode to combine multiple units for up to 6000 W in a single voltage class. Series mode doubles the voltage ceiling.

Why Choose UDP5000?

Constant Power Architecture

Full rated power across the V/I envelope, not just at a single voltage. A 2000 W unit delivers 2000 W at 50 V and at 200 V — useful range, not a marketing peak.

20-Model Matrix

5 voltage classes × 4 power levels gives 20 combinations — find a unit that fits your load without overbuying voltage or power you won't use.

Series and Parallel Combining

Combine units in series for higher voltage, parallel for higher current. Scale to 6000 W and beyond using same-model parallel groups.

5-Year Warranty

3 years plus 2-year extension on every UDP5000 — parts and labor. Two years longer than the industry standard 3-year terms.

FAQ

What does "constant power" mean?

Traditional power supplies have a single rated voltage and current — e.g., 40 V × 40 A = 1600 W rated point, but at lower voltages the current ceiling is the limit. Constant-power supplies (like UDP5000) deliver full rated wattage across most of the V/I curve, so a 400 W / 40 V unit can also deliver 400 W at 20 V × 20 A, 10 V × 40 A, etc.

Can I combine multiple UDP5000 units?

Yes. Same-model units can be combined in series (doubles voltage ceiling) or parallel (sums current, up to 3 units in parallel for 3× power). Common applications: 1600 V series-pair for HVDC, or 6 kW parallel groups for EV pack test.

What's the difference between switching and linear DC supplies?

Switching supplies (like UDP5000) are smaller, lighter, more efficient, and more programmable — ideal for production test, ATE, and any application where you need significant power per rack U. Linear supplies have lower output noise and faster transient response — better for low-noise analog work and very fast load steps. UDP5000 is switching.

Suitable for automated test systems?

Yes. Full SCPI command set, LAN/USB standard, optional GPIB. List mode supports up to 50 programmable steps from front panel or USB import.

How is constant current handled?

UDP5000 supports both CV (constant voltage) and CC (constant current) operation with automatic crossover. List mode programs both modes with arbitrary timing for battery cycling and electronic-load-like profiles.

What's in the 5-year warranty?

Parts and labor for 5 full years. Standard on every UDP5000 — no registration or extended warranty purchase required.

Twenty models, one architecture — choose the UDP5000 that fits your voltage class and your load.
