RSR Electronics 3010 Triple Output DC Power Supply

The RSR Electronics 3010 is a regulated DC power supply engineered for laboratory testing, system integration, and electronic development. It delivers three independent outputs - one fixed 5V rail and two variable supplies - with current limiting and short-circuit protection across all channels. The unit operates from 115V AC input and measures 8" × 7.75" × 4.25", making it suitable for benchtop and rack-mount integration into existing test systems.

Technical Specifications

The 3010 provides a 5V DC fixed output at up to 3A with 0.2% line regulation and 1% load regulation. Maximum output ripple on this channel is 10 mV p-p. Two independent variable outputs each supply ±1.5V DC to ±15V DC at 1A maximum, with 0.5% line regulation, 1% load regulation, and 10 mV p-p ripple specification. All outputs feature full current-limit protection and short-circuit immunity.

Key Features

• Three isolated output channels for multi-voltage applications


• Fixed 5V @ 3A output with tight line regulation (0.2%)


• Dual variable supplies: ±1.5V to ±15V DC @ 1A each


• Low output ripple: 10 mV p-p across all channels


• Fully current-limited and short-circuit protected


• Compact 6.95 lb chassis

Typical Applications The 3010 is well-suited for powering analog and digital circuits during development and troubleshooting. The combination of fixed and variable outputs makes it effective for circuits requiring multiple supply rails, including operational amplifier test benches, logic circuit characterization, and mixed-signal prototype validation.

Compatibility & Integration Designed for straightforward integration into existing laboratory systems, the 3010 accepts standard 115V AC mains input and presents outputs suitable for direct circuit connection. Its compact footprint and multi-output architecture support efficient benchtop layouts and modular test rack configurations.
