## High-Voltage Laboratory Power Supplies for R&D Tests

For R&D tests requiring high voltage and precise operation, Voltcraft's VSPP series is offered through the Conrad Sourcing Platform. These power supplies particularly stand out in e-mobility, biomedical device, and renewable energy validation applications.

In laboratory tests, controlled DC levels far exceeding standard desktop power supplies are needed in the field of power electronics. The VSPP series bridges the gap between precise measurement and high-energy tests, meeting both laboratory and industrial requirements.

### VSPP Series Technical Specifications

• Output voltage: Continuously adjustable from 0-600 VDC
• Power range: Models between 1200 W and 3000 W
• Voltage accuracy: ≤0.05%, offset ±20 mV, ±50 mV, or ±100 mV depending on model
• Current accuracy: ≤0.05%, ±20 mA or ±30 mA deviation
• Low noise output: Suitable for sensor calibration and electronic characterization
• Modular design: Voltage or current can be increased with series and parallel connection
• Maximum parallel connection: 300 A current output possible with 10 power supplies
• Connections: USB, LAN, RS-485
• Chassis compatibility: Suitable for standard 19-inch laboratory and battery test racks

### Flexible Programmability for Automated Test Equipment
Thanks to built-in linked list programmability, the devices can store and run voltage and current sequences directly on the device. This allows for automated testing without the need for a computer for repetitive measurement cycles in power electronics tests.

Remote control ensures easy integration with external automation software in digital supply chain environments. The universal input voltage is designed for 85 VAC - 265 VAC at 50/60 Hz.

### Application Areas

• E-mobility battery module characterization
• Isolation and leakage testing in biomedical devices
• DC-link and inverter validation in renewable energy converters
• Stress testing of power semiconductors

The VSPP series maintains laboratory-level measurement accuracy while bringing tests closer to industrial conditions, thereby facilitating critical validation tasks in R&D processes.
