GPR-H Series Linear D.C. Power Supply

Key Features

Low ripple and noise for precise performance
High stability linear regulation design
Adjustable voltage and current with fine control
Overvoltage and overload protection
Bright LED display for easy monitoring
Durable construction with convection cooling
Suitable for lab, educational, and industrial use

The GPR-H Series Linear D.C. Power Supply is engineered with cutting-edge linear regulation technology to provide stable, low-noise performance—maintaining ripple levels typically below 1 mVrms—for applications where precision is paramount. Designed for demanding laboratory, educational, and industrial environments, this high-precision, single-output unit delivers an impressive range of voltage and current outputs, which can be finely controlled via its 10-turn potentiometers, ensuring that even the most sensitive analog and communication circuits receive consistent, reliable power. Enhanced safety features, including integrated overvoltage, overload, and reverse polarity protection, ensure both the power supply and connected equipment remain secure under variable load conditions. The intuitive front panel, featuring a bright LED display, offers clear, real-time monitoring of operating parameters, while the robust metal chassis and silent convection cooling system contribute to its long-lasting durability and quiet operation in both bench-top and rack-mounted setups, making it a trusted solution for critical test and research applications.
