Seaward Sentinel 501 Electrical Safety Tester

The Clare Sentinel 501 electrical safety tester (manufactured by Seaward) enables manufacturers to check their products in-house to ensure compliance with the relevant international technical conformance standards. Significant time and cost saving benefits are provided by the Sentinel 501 bench-top Hipot/flash tester from Clare, which deliver improved type testing during product development or enhanced compliance testing in a laboratory environment. A remote start terminal and signal I/O port allows for remote starting, safety interlocking and PLC control while an enhanced safety feature will automatically cut off the output voltage within 150?s where normal output voltages are detected or when the upper or lower current trip limits are reached while the device is under test. The Sentinel series is ideal for R&D facilities and compliance laboratories, while design, quality assurance, and manufacturing and production engineers will also benefit from the easy-to-use safety test features.
