UNI-T UDP5800-10 2000W Programmable DC Switching Power Supply (800V, 10A)

Overview

The UNI-T UDP5800-10 is a single-channel 2000W programmable DC switching power supply delivering 0.5–800 V and 0–10A with auto-ranging across the rated power envelope. It brings the same platform-level accuracy, source-emulation capability, and SCPI remote control as the rest of the UDP5000 family to high-voltage applications β€” 400 V and 800 V EV traction batteries, high-string PV, industrial DC bus β€” that lower-voltage tiers cannot reach.

Voltage accuracy is Β±(0.05% of set + 0.05% of rated) and current accuracy Β±(0.5% of set + 0.1% of rated); voltage ripple is held to 250mV p-p with a 100 ppm/Β°C temperature coefficient. A 2.4-inch TFT-LCD shows voltage, current and power together, and full SCPI control over USB and LAN drops the UDP5800-10 straight into LabVIEW, Python-VISA or any ATE framework.

Choosing Your Model β€” UDP5000 Series

The UDP5000 name spans 20 models built on one platform: five voltage classes (40 V / 80 V / 160 V / 250 V / 800 V) across four power classes (400 W / 800 W / 1200 W / 2000 W). They differ only in output range and chassis size β€” control, accuracy, protection and interface are otherwise identical. Compare the full series before selecting:

Every model shares the same chassis architecture, control system, regulation accuracy, protection suite, and interface set. The 800 V UDP5800 tier does not support series connection; all other tiers support series and parallel combining. Choose by the voltage class that covers your rail and the power class that covers your load β€” output range and chassis height scale with power, the instrument does not change.

CC/CV Priority β€” Protect the Device, Not Just the Supply

Most bench supplies treat the CC/CV crossover as a fixed hardware behaviour. The UDP5000 lets you choose which parameter takes priority at turn-on and during mode transitions. CV-priority establishes the target voltage first β€” the right choice for capacitor banks, converter input rails, and battery packs where voltage overshoot must be bounded. CC-priority brings current up under control β€” the right choice for electrolysis cells, formation rigs, and any load where inrush must be limited at 800 V.

Adjustable Slew Rate β€” Control How Fast Power Arrives

Voltage and current slew rates are independently settable. At 800 V, a controlled ramp is not optional β€” capacitive DUTs, battery packs, and film capacitors under formation all need current and voltage to arrive at a rate the load can absorb safely. High-speed mode is available when fast settling is the test requirement.

Internal Resistance β€” Simulate High-Voltage Source Impedance

The internal variable-resistance function (set in CV mode, up to 60Ξ© in 1 mΞ© steps) makes the terminal voltage droop with load current exactly as a high-voltage battery pack or fuel cell stack would β€” no external resistor, no thermal risk at 800 V, value changeable instantly from the panel or over SCPI.

Front & Rear Outputs β€” Bench-Ready and Rack-Ready

Output terminals are provided on both panels. Front terminals are available for quick hookup; rear terminals keep permanent rack wiring clean and away from the high-voltage output when mounted in a test rack. Both share the same output β€” front-panel draw is limited to 10 A, so high-current loads belong on the rear.

List Mode & Discharge Control β€” Automate Output Sequences

List Mode runs up to 128 programmed V/I/dwell steps for 1 to 9,999 or infinite cycles, stored locally or exported, executing with no PC attached β€” built for overnight formation runs, pack ageing cycles, and unattended production routines at 800 V. The internal discharge load bleeds output capacitance down rapidly when output is switched off.

Multi-Unit Parallel β€” Scale Current When You Need More

Up to 2 identical units combine in parallel for proportionally higher output current, coordinated over the rear CAN / LS_BUS interface from the master unit or a single SCPI connection; unit-to-unit current balance stays within ~5% of rated. Series connection is not supported on the UDP5800 at 800 V.

Frequently Asked Questions

Can I use the front and rear output terminals at the same time?

Both terminal sets are parallel connections to the same single output. You can wire both, but the front terminals are limited to 10 A maximum β€” route high-current loads to the rear panel.

What is the difference between the VHS/IHS and VSR/ISR slope modes?

VHS (CV high-speed) and IHS (CC high-speed) use the supply's default fast rise and fall rates. VSR (CV slope) and ISR (CC slope) let you set the rise and fall rate so output ramps in controlled fashion β€” at 800 V this is critical for capacitive and battery loads that cannot absorb uncontrolled current at turn-on.

Does the internal-resistance function need an external resistor?

No. The internal variable-resistance function electronically emulates source impedance (set in CV mode, up to 60Ξ© in 1 mΞ© steps), so the supply behaves like a high-voltage battery pack or fuel cell stack with no physical resistor and no added thermal risk.

Can multiple units be combined for more power?

Yes, up to 2 identical units in parallel for more current (2000 W tier), coordinated from the master unit or a single SCPI connection; unit-to-unit balance stays within ~5% of rated. Series connection is not supported on the UDP5800 β€” the 800 V output already reaches the system ceiling for this platform.

How does it integrate with automated test?

USB and LAN with full SCPI 1999.0 / IEEE-488.2 support LabVIEW, Python-VISA and any standard ATE framework; List Mode runs stored sequences stand-alone without a connected PC.
