Telonic Instruments have introduced a new range of Hipot (Flash) and Insulation Resistance testers manufactured by Japan based Kikusui. Designated the TOS5300 the three models in the range are designed for use in Withstanding Voltage and Insulation Resistance testing to help ensure the safety of Electrical / Electronic components / equipment. Incorporating and innovative PWM amplifier that achieves high stability and has an input voltage regulation of.3%. The series offer rise and fall time control of the test voltage and a stable output which is unaffected by mains voltage variations, plus the ability to select 50 or 60Hz test frequency. Upper and lower current limits can be set within the range of 0.01mA to 110mA in AC mode and 0.01mA to 11mA in DC mode. AC test voltage is settable from 0.05kV to 5kV. D.C test voltages can be varied from 0 to 6kV. There are three models in this versatile range which consist of: 1. TOS5300 which is for withstanding voltage AC testing up to 5kV. 2. TOS5301 has AC and DC withstanding voltage test capability with AC up to 5kV and DC up to 6kV. 3. TOS5302 has 5kV AC withstanding voltage test capability, plus an insulation test function with test voltages from 25V to 1000V. All models will operate from any global AC input voltages and frequencies; and are equipped with a USB interface. Easy to use controls and a large L.C.D. panel feature on the front panel. Weighing approx. 15kg’s These products have applications right across Industry and Research Labs.
