Detailed Product Overview
Insulation resistance testing of PV systems is often carried out during daytime service work. PV strings generate DC voltage as long as they are exposed to light, even when the inverter is switched off. Standard insulation or installation testers will not start the test if external voltage is detected.Full Insulation Tester for Low-Voltage Systems
The IR4053 is a battery-powered insulation tester for low-voltage installations and is used for standard insulation testing of distribution boards, motors, cables and electrical equipment in addition to PV measurements. The instrument provides five selectable test voltages from 50 V to 1000 V and measures insulation resistance up to 4000 MΩ.Fast PASS/FAIL Evaluation
For routine testing, the IR4053 includes an integrated comparator function. The measured insulation value is automatically evaluated against a user-defined threshold and indicated as PASS or FAIL.Designed for Everyday Use
The IR4053 complies with CAT III 600 V and has been tested for a 1 m drop. An integrated hard case forms a single unit with the instrument and provides storage space for test leads and accessories. The leads remain connected to the tester during transport. The display offers high contrast for clear readability under varying lighting conditions. An integrated backlight supports measurements in poorly lit distribution boards and technical cabinets.- IR4053 Digital Insulation Tester
