ITEU-SP4K / ITEU-TP Series — LISUN Isolation Transformer
LISUN ITEU-SP4K Isolation Transformer — 4kVA galvanic isolation transformer for EMC test benches, breaking the direct mains ground reference to the device under test.
Enquire About This Product
Overview
The ITEU-SP4K Isolation Transformer provides full galvanic isolation between the mains supply and the device under test, breaking the direct ground reference path. This is a standard requirement for many EMC test setups (isolating the DUT from mains-borne noise and providing a controlled ground reference) and for safety isolation when servicing energised equipment. The series spans single-phase models (ITEU-SP1KS to SP10K, ITUS-SP1KS/SP2K/SP5K) through higher-power three-phase models (ITEU-TP380V10K, ITEU-TP20K, ITUS-TP10K) for larger EUTs.
