    Clare Sentinel 501 Electrical Safety Tester - AC/DC Hipot Tester

    The Clare Sentinel 501 Electrical Safety Tester is a comprehensive dielectric tester designed for electrical appliance testers, compliance engineers and production facilities. It boasts the highest specification offered within the Sentinel range, including the following features in order to comply with international electrical safety testing standards:

    • 5kVAC dielectric strength test
    • 6kVDC dielectric strength test
    • 32A Earth bond test – Sentinel 501 only
    • 1kVDC insulation resistance test – Sentinel 501 only
    • 500VA power output
    • ARC detection

    The dielectric tests on the Sentinel 501 can be programmed to gradually ramp up voltage output and can even freeze voltage outputs for a set time of up to 999.9 seconds. This enables certain test criteria to be met, but also avoids damage being cause to equipment under test. AC/DC dielectric outputs can also be programmed in steps of 2V at a time, consequently increasing accuracy of the current measurement that is displayed at a resolution from as low as 1µA (±1.5% +30µA).

    The Clare Sentinel 501 includes the effective ‘Sweep function’. This is an imperative feature allowing R&D engineers to see whether any electrical parameters change over a period of testing, with resultant measurements displayed in a graph format upon the LCD display.

    Full system integration is possible with all of the Sentinel models, allowing for operation within a PLC circuit in order to satisfy ISO production standards. Manual operation is very straightforward using the instrument facia and remote control is possible using the signal I/O port.

    The Clare Sentinel Safety Testers are suitable for use in R&D facilities and quality compliant environments such as manufacturing production lines. Engineers will find the instruments easy to use, whilst benefitting from an all-in-one test solution.

    Electrical Test Compliance for Manufacturers 

    Worldwide technical standards are in place to ensure various electrical safety and performance targets are met when electrical products are manufactured in order not pose a danger to the end user. Products must adhere to the requirements of relevant product safety standards if they are to meet the requirements of certain test standards.

    The Clare Sentinel Electrical Safety Testers comply with IEC, EN, UL and CSA electrical test standards to name a few, the BSEN and North American electrical safety standards are as follow:

    • British Standard: BS EN 60598-1 sets out the general requirements for luminaires, including lighting equipment that operates from supply voltages of up to 1000V. All the requirements and tests covered in this standard relate to the classification, marking, mechanical design and electrical construction. BS EN 60598-1 looks at all the aspects of electrical safety, as well as thermal and mechanical safety. It’s also important to take into account that these requirements apply to luminaires with igniters built in and separate from ballasts.
    • North America: UL 1598 applies to luminaires for use in non-hazardous locations and that are intended for installation on branch circuits of 600 V nominal or less between conductors in accordance with the Canadian Electrical Code, Part I (CEC), CSA C22.1, with the U.S. National Electrical Code (NEC), ANSI/NFPA 70, and with the Mexican National Electrical Code, NOM-001-SEDE.
