Isolation transformer

Manufacturers require certain thin film and back contact crystalline PV panels to be earthed on the DC side. The CS IT20 isolation transformer applies these panels in the best possible way in combination with the CS15TL and CS20TL inverters. The use of high-quality materials ensures an excellent output, while the offline function reduces night consumption to zero.

The robust IP54 casing is suitable for outside installation and fitted with a regulated fan with an easily replaceable filter. The enclosure consists of several individually removable parts that block the hoisting eye from view and simplify installation while keeping cables and clamps easily accessible.
