UDP5080-60 1200W 80V/60A Programmable DC Switching Power Supply

Overview

The UNI-T UDP5080-60 is a single-channel 1200W programmable DC switching power supply delivering 080V and 060A with auto-ranging across the rated power envelope. It pairs a wide output range with the regulation accuracy, source-emulation and remote control expected of a professional programmable supply.

Voltage accuracy is (0.05% of set + 0.05% of rated) and current accuracy (0.5% of set + 0.1% of rated); ripple is held to 50mV p-p with a 100 ppm/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 UDP5080-60 straight into LabVIEW, Python-VISA or any ATE framework.

Choosing Your Model 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 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 output range and chassis height scale with power, the instrument does not change.

CC/CV priority mode transition behaviour

CC/CV Priority 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 the right choice for microcontrollers, FPGAs and analog rails. CC-priority brings current up under control the safer choice for LEDs, laser diodes and battery charging where inrush must be bounded.

Adjustable Slew Rate Control How Fast Power Arrives

Voltage and current slew rates are independently settable. A slower ramp prevents inrush into capacitive loads, reduces mechanical stress on motor windings at start-up and gives sensitive analog circuits time to settle; the high-speed default mode is there when fast settling is what the test needs.

Internal Resistance Simulate Real Power Sources

The internal variable-resistance function (set in CV mode, up to 1.333 in 1 m steps) makes the terminal voltage droop with load current exactly as a battery, fuel cell or solar panel would no physical resistor, no thermal risk, value changeable instantly from the panel or over SCPI.

Front & Rear Outputs Bench-Ready and Rack-Ready

Output terminals are provided on both panels. Front terminals are there for quick prototype hookup; rear terminals keep permanent rack wiring clean. Both are the same single output front-panel draw is limited to 10 A, so high-current loads belong on the rear.

List Mode & Discharge Control Automate Output Sequences

List Mode runs up to 128 programmed V/I/dwell steps for 1 to 9,999, infinite cycles or continuously, stored locally or exported, executing with no PC attached built for overnight burn-in, charge-profile runs and production routines. The internal discharge load bleeds output capacitance down rapidly when output is switched off.

Multi-Unit Operation Scale When You Need More

Up to 2 identical units parallel for more current, or up to 2 series for more voltage, coordinated over the rear CAN / LS_BUS interface from the master unit or a single SCPI connection; unit-to-unit balance stays within ~5% of rated.

Display and Control

A 2.4-inch TFT-LCD presents voltage, current and power simultaneously with a concise multifunction keypad; external analog control (010 V setpoint plus digital ON/OFF) is available on the rear analog interface for closed-loop and HIL setups.

Applications

Power-Electronics and Motor-Drive Development

080 V spans 48 V / 60 V / 72 V battery and DC-bus rails common in motor-drive and industrial converter design. Adjustable slew rate controls how fast the bus is energised into capacitive DC links.

R&D Bench and Production

List Mode and SCPI scripting make repeatable bring-up and end-of-line routines straightforward without an attended operator.

Automated Test and Production

SCPI over USB or LAN plus stored List Mode sequences make the UDP5000 a clean fit for unattended characterisation, burn-in and end-of-line test.

Accessories and Family Options

In the box: power cord (destination-country standard, 1.8 m), four-conductor analog-interface flat cable (3.5 m), USB cable (1.5 m), M3 mounting screws, output-terminal protection cover, and rack distribution bracket.

The UDP5000 series spans 16 models on one platform see Choosing Your Model above for the full voltage power matrix if a different rail or load fits your application better.

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 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 useful for capacitive and motor loads, and for sensitive analog circuits that need settling time.

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 1.333 in 1 m steps), so the supply behaves like a battery, fuel cell or solar source with no physical resistor and no added thermal risk.

Can multiple units be combined for more power?

Yes. Identical models combine for more current (parallel, up to 2 units) or more voltage (series, up to 2 units), controlled from the master unit or a single SCPI connection; unit-to-unit balance stays within ~5% of rated.

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.
