The Megger Insulation Resistance Tester MIT515/2 is a reliable instrument for insulation testing of electrical equipment in industrial and power supply environments. Here's an overview:
Insulation resistance testing range up to 10 TΩ, with ±5% accuracy up to 1 TΩ and ±20% accuracy up to 10 TΩ at 5 kV.
Includes a variety of industry-standard test functions, including insulation resistance (IR), insulation resistance versus time (IR(t)), polarization index (PI), dielectric absorption ratio (DAR), and PI prediction (PIP).
User-definable test voltages from 40 V to 1 kV in 10 V steps, and from 1 kV to 5 kV in 25 V steps.
A fast-charging lithium-ion battery provides up to 6 hours of continuous testing on a single charge. A 30-minute quick charge provides 1 hour of operation, and AC power is also available when needed. High safety performance: CAT IV 600V safety rating at altitudes up to 3000 meters. Its dual-shell design provides IP65 protection against dust and moisture.
Includes a 3-meter medium-insulated test lead.
