Insulation testers from Megger offer variable test voltages
Norristown, PA. Megger has enhanced its MIT400/2 series of insulation and continuity testers. These CAT IV 600-V rated instruments feature an adjustable insulation test voltage from 10 V to 1000 V in 1-V steps, giving them a much tighter control of test voltage as well as conformance to specific standards and requirements mandated by regulatory agencies.
The MIT400/2 Series is suitable for electrical installations, cable testing, and motor testing as well as in automotive, ESD, panel building, avionics, and maintenance applications. It provides greater user safety when testing in higher voltage environments.
The MIT400/2 Series, which includes the MIT400/2, MIT410/2, MIT420/2, and MIT430/2, offers test ranges from 2 GΩ to 200 GΩ, with test voltages ranging from 50 V to 1000 V. The testers have also been enhanced with feedback-controlled test voltages to limit overvoltage to 2%, below the accepted industry standard of 10% to 20%.
The series features a stabilized insulation test voltage to ensure it remains within tolerance to industry/regulatory standards as well as a single resistance range with significantly faster continuity testing ranging from 0.01 Ω to 1 MΩ. It also features rechargeable options for AC power and car charging.
These enhanced units feature DC voltage measurements (up to 600 V) as well as true RMS measurements, allowing for accurate data acquisition on noisy lines. Voltages are displayed on a smaller digital readout on the instrument, while the actual test measurement range is shown on a larger digital display during the test.
Polarization index (PI), dielectric absorption ratio (DAR) function, and adjustable continuity pass/fail limit alarms are featured on all units. Continuity test currents from 200 mA or 20 mA are available.
For safety, each tester features live circuit detection and protection. All instruments are over-molded for increased protection and sealed to IP54, providing a weatherproof case to lessen the chance of water ingress.
The MIT400/2 series feature a back-stand and a battery compartment for 6 AA batteries with separate fuse access. Bluetooth wireless data transfer and test results storage are available on the MIT430/2.
