Whether you're conducting critical testing, prototyping, or ongoing production work, the UDP4303S will deliver accurate and reliable results, ensuring your projects move forward with confidence.

The UDP4303S boasts four fully isolated channels, enhanced resolution, fast sampling, and a host of advanced features designed to meet your most demanding needs. With its intuitive interface and robust protection mechanisms, this power supply guarantees ease of use while maintaining safety and performance standards.

Key Features & Benefits:

Four Independent Channels (CH1 & CH2: 32V/3A, CH3: 15V/3A, CH4: 6V/10A)
Provides flexibility for various applications, whether you need high voltage or high current, without the need for external wiring.
High-Resolution Output with Low Noise
Achieve ultra-fine resolution down to 1 µA for more accurate testing. With low ripple voltage and noise, the UDP4303S ensures that the quality of your output is pristine.
Fast Sampling Rate (8 kSa/s)
Captures transient changes and provides highly detailed data, perfect for applications requiring high-fidelity outputs.
1ms Programming Resolution
Allows for precise control and output of arbitrary waveforms, improving your ability to fine-tune performance across all four channels.
Multiple Display Styles on a 4.3-Inch LCD Screen
Offers six different interface styles to suit your testing preferences, ensuring clarity and ease of data interpretation.
Remote Control & Web Access
Manage the power supply remotely via LAN, USB, or web browser, offering flexibility for large-scale operations or difficult-to-access setups.
Comprehensive Protection Features
Includes adjustable overcurrent protection (OCP), fast transient response (<50 μs), and overvoltage protection (OVP) to ensure the safety of your devices.

Why Choose the UDP4303S?

Ultra-Fine Control for Precise Results
The UDP4303S offers programming and read-back resolutions of 1mV and 1μA, ensuring that your projects can achieve the highest levels of precision. Ideal for sensitive applications like battery testing or sensor development, where even minute fluctuations can have significant impacts.

Improved Workflow Efficiency
The UDP4303S supports list and delayer functionality, making it easier to automate complex tests. Save up to 10 status files, list files, and delayer settings directly on the device or to a USB for quick retrieval in future projects.

High Sampling and Fast Transient Response
Capture fast-moving signals or power fluctuations with a sampling rate of 8 kSa/s. The UDP4303S is ideal for applications requiring real-time adjustments and high data accuracy, allowing you to monitor and respond to changes as they happen.

Enhanced Protection for Safety
Protect your sensitive devices and circuits with fast, adjustable overcurrent protection (OCP) that can be customized to respond in as little as 3ms. The adjustable delay feature ensures false triggers are minimized, improving reliability in high-stakes testing scenarios.

Advanced Features That Set It Apart

Customizable Display Styles
Choose between six different interface styles to match your workflow preferences and improve ease of use.

Bleeder Circuit
The controllable bleeder circuit allows for flexible battery testing by enabling or disabling the circuit based on the test needs. Turning it off prevents unnecessary discharge, preserving battery life, while turning it on allows for rapid voltage reduction during stress tests. This feature ensures precise control, making it ideal for accurate battery diagnostics and performance evaluations.

Channel Tracking
The UNI-T UDP4303S allows users to synchronize settings between channels for efficient multi-channel operation. When enabled, any adjustments made to one channel automatically apply to the corresponding channel, streamlining workflow and saving time. This is particularly useful for scenarios requiring consistent outputs across multiple channels, ensuring faster, more accurate testing.

Full Channel Remote Compensation
This feature on the UNI-T UDP4303S ensures accurate voltage readings by compensating for any losses over long test leads across all four channels. Additionally, it supports reverse connection and overvoltage protection, safeguarding both your equipment and test devices. This combination guarantees precision and safety, making it ideal for complex testing environments.

Series and Parallel Operation
Effortlessly configure series or parallel outputs for more demanding applications, with no performance degradation.

Complete Data Management & Analysis
The built-in recorder logs voltage, current, and power across all channels, ensuring that all critical data is saved and easily retrievable for later analysis.

Flexible Testing Configurations
With its series and parallel output capabilities, you can effortlessly switch between high-voltage and high-current needs, without the need for cumbersome rewiring. The 4-channel full isolation ensures there’s no crosstalk, giving you the flexibility to configure setups that meet your exact requirements.

With a sleek design, user-friendly interface, and a full suite of professional features, the UDP4303S Programmable Linear DC Power Supply is the ultimate solution for your lab or testing environment. Experience greater precision, control, and safety—all in one powerful package.
