Zulu Code Model

Description

5500V insulation resistance tester, EMI noise rejection, surge arrestor/generator testing

Did you know

The Amprobe AMB-55 Industrial High-Voltage Insulation Tester was introduced around March 2017. It is part of Amprobe's line of high-voltage insulation testers designed for professional diagnostics.
The AMB-55 is positioned as an advanced industrial high-voltage insulation tester within Amprobe's range, offering testing voltages up to 5000V. It sits alongside the AMB-110, which provides even higher test voltages up to 10,000V, and the more basic AMB-50, which also tests up to 5000V but with fewer advanced features.
This model is chosen for its comprehensive diagnostic capabilities, including automated calculations of Polarization Index (PI), Dielectric Absorption Ratio (DAR), and Dielectric Discharge (DD), along with a step voltage test. Its ability to perform accurate insulation testing in noisy environments due to built-in noise rejection filters and shielded test leads is also a key strength.

Model	Max Test Voltage	Max Insulation Resistance	Diagnostic Tools	Memory Storage
AMB-55	5000V (in 25V increments)	10 TΩ	PI, DD, DAR, Step Voltage, R(t) graph	1000 measurements
AMB-110	10,000V (in 25V increments)	10 TΩ	PI, DD, DAR, Step Voltage, R(t) graph	1000 measurements
AMB-50	5000V (500/1000/2500/5000V)	1 TΩ	PI, DAR, Pass/Fail Comparison	18 measurements
