SCI – Model 448

מאפיינים מרכזיים

500VA, 5kV @ 100mA AC Hipot, 6kV @ 10mA DC Hipot, Insulation Resistance, 40A AC Ground Bond, CE Listed

Our 448 model is a 4-in-1 tester with 500VA AC Hipot, DC Hipot, Insulation Resistance and Ground Bond testing capabilities. The 448 is capable of a 500VA AC Hipot output to comply with 100mA leakage current test compliance requirements. This tester features a simple design and easy-to-use interface, reducing setup time and increasing production-line throughput for your application. The 448 is equipped with multiple memories and an optional USB port for remote BUS communication so you can quickly perform tests on a variety of DUTs from the front panel or with a PC. Add to user safety by equipping your tester with Personal Protective Equipment (PPE) via the built-in safety interlock.
