Description
SMC Quasar Smart Relay Tester

- 4 x 300V + 3 x 60A outputs, switchable to 7 current outputs
- 6 binary inputs + 4 binary outputs
- External DC current and voltage measurement
- 6 low-level outputs to test sensors, meters etc, and to upgrade with more channels
- Integral Wi-Fi, Ethernet LAN, dedicated IEC-61850 port and Expansion port
The Quasar is the most advanced three-phase relay test set designed for the testing of secondary and IEC-61850 protections of any type with special focus on industrial and routine maintenance applications.
Born to be industrial
The Quasar is built for endurance in aggressive work conditions including extreme temperature, dust, and harsh transportation. It is encapsulated in first class protection ABS casing and features integral wheels and extensible handle, which makes it remarkably transportable when added to its compact size and reduced weight. You will save the money and annoyance of adding a bulky transport case.
All the connections are clearly identified on the top surface and you can remove the cover by just sliding it to one side if you wish.
Everything in the Quasar’s operation is designed for testing speed, accuracy and efficiency. Collecting a report with the results of your tests will be a matter of making the connections and running the procedures that you have prepared and saved beforehand for each relay type.
The flexible AC input will accommodate virtually any supply with 50 or 60 Hz.
You will find plenty of serviceable parts inside! Actually, the Quasar is made up of plug in modules that are easy to replace, and the software includes a guided calibration process that can be followed by any qualified laboratory. You will never need to return your Quasar for service. Furthermore, it is furnished with upgrade ports for additional test channels and functional enhancements.
Unit Features

IEC-61850 inside
The Quasar features a dedicated Ethernet port complying with the latest specifications dictated by the IEC for modern control, automation and protection architecture. You can interchangeably use the same test routines for any relay type regardless the environment (wired or message based) where it will be installed.
Direct for simple, automated for complex
You can do a fast, simple verification on a few characteristic points of a working protection with your tablet or launch ROOTS in your Windows PC for comprehensive, fully automated testing and reporting of the protection function. The Quasar is the perfect companion for any of the two control approaches
