The Quasar-C+ is a powerful and scalable relay test set designed for protection relay testing applications where full current output capability is essential.
It includes the same dedicated current sources as the Quasar and one configurable V4 voltage output, which can operate as 1 x 300 Vac, 1 x 5 A, 1 x 300 Vdc, or as a battery simulator with 48, 125, or 250 Vdc levels. If four voltage outputs are required in the future, the Quasar-C+ can be upgraded to a full Quasar configuration by replacing the default voltage amplifier with the standard four-output voltage amplifier.
Looking for a powerful and flexible relay test set for protection relay testing, secondary injection testing, IEC 61850 applications, and GOOSE-based digital substation schemes? The Quasar-C+ Smart Relay Tester is designed for professionals who need the full current output capability of the Quasar platform, combined with a highly flexible configurable voltage channel.
The Quasar-C+ relay tester includes the same dedicated current sources as the Quasar, making it an excellent solution for overcurrent, differential, distance, and protection relay testing applications where strong current injection capability is essential. In addition, it includes one configurable voltage output, V4, which can operate as a fully programmable voltage channel or as a flexible auxiliary output for AC voltage, DC voltage, current output, or battery simulation.
