• Configurable V4 Voltage Output: The V4 output can operate as a fully configurable voltage channel, offering high flexibility for secondary injection testing and protection relay validation.
• Multiple V4 Operating Modes: The V4 channel can be configured as 1 x 300 Vac, 1 x 5 A, 1 x 300 Vdc, or as a battery simulator with 48, 125, or 250 Vdc output.
• Secondary Injection Test Set for Current-Based Protection: The Quasar-C+ is especially suitable for overcurrent, differential, earth fault, breaker failure, and other protection functions where accurate current injection is essential.
• IEC 61850 and GOOSE Testing: The Quasar-C+ supports IEC 61850 and GOOSE-based testing, making it suitable for modern digital substation applications and communication-based protection schemes.
• Flexible Battery Simulation: The configurable V4 channel can be used as a battery simulator with selectable 48, 125, or 250 Vdc levels, allowing users to simulate common substation DC auxiliary supply voltages.
• Relay Testing Software: The Quasar-C+ works with intuitive relay testing software for manual, automated, and preconfigured tests, helping users reduce testing time and improve repeatability.
• Multiple Connection Modes: The Quasar-C+ supports convenient connection options for field, substation, and laboratory environments.
• Rugged and Portable Design: Built for field use, the Quasar-C+ is designed for professionals who need reliable relay testing equipment in demanding environments.

Configurable V4 Output for Maximum Flexibility

One of the key features of the Quasar-C+ relay test set is its configurable V4 output. Unlike conventional current-focused relay testers, the Quasar-C+ gives users an additional flexible channel that can be adapted to different testing needs.

• 1 x 300 Vac for AC voltage injection and protection relay testing.
• 1 x 5 A for additional current injection when required.
• 1 x 300 Vdc for DC voltage testing applications.
• Battery simulator with selectable 48, 125, or 250 Vdc output levels.

This flexible output makes the Quasar-C+ a practical secondary injection test set for users who need strong current outputs and one versatile voltage or DC auxiliary channel.

Upgradeable to Full Quasar Configuration

The Quasar-C+ is designed as a scalable version of the Quasar platform. It includes the same dedicated current sources as the Quasar and one configurable V4 voltage output as standard.

If full four-channel voltage capability is required in the future, the Quasar-C+ can be upgraded to a complete Quasar configuration by replacing the default voltage amplifier, which includes one voltage output, with the standard Quasar voltage amplifier offering four voltage outputs.

This upgrade can be performed at any time by purchasing the standard voltage amplifier module, allowing users to expand their relay test set without replacing the complete equipment.
