Control- and isolating transformer
UTT1-6-23
Characteristics
General data
The control transformers of the UTT1 series feature a universal input voltage range and ensure safe galvanic isolation of the primary circuit from the secondary circuit. The multifunctional base brackets provide variable mounting options, and the upright design reduces space requirements. The integrated crane eyelets facilitate transport and installation.
