Megger SMRT410 Relay Tester

The Megger SMRT410D is a multipurpose, lightweight, field-portable test set that can assess a range of motor overload relays, electro-mechanical protective relays, solid-state protective relays, and microprocessor-based protective relays, among other protective devices.

The device can be controlled manually using the built-in touchscreen user interface (STVI) or fully automated using the Relay Test Management Software (RTMS), which runs on a PC. The device can also be utilized with third-party applications, such as National Instruments LabVIEWTM, thanks to the open communication design.

The Smart Touch-View InterfaceTM (STVI), Megger’s second generation of automatic/semi-automatic manual user interface software, is the built-in user interface. It features a sizable, simple-to-read, full-color, high-resolution, high-definition TFT LCD touch-screen display that shows meter values including AC and DC amperes, AC and DC volts, and time in both seconds and cycles. Other values may be displayed, such as Phase Angle, Frequency, Ohms, Watts, VA, or Power Factor, depending on the type of test chosen.
