Toroidal fixed transformer, open
The toroidal fixed transformer in open design as a mains, auto, safety or isolation transformer Description Toroidal transformers offer significant advantages over conventional transformers: Their design results in up to 50% less volume with low weight. Since the toroidal cores have almost no air gap, only a very low magnetic stray field is generated, and the transformers are almost hum-free. Between no-load and full load, the change in secondary voltage is many times smaller than with laminated core transformers. Benefits Adaptation of mains voltage to different output voltages No humming Low magnetic stray field Low voltage drop Minimum overall weight small dimensions Connection with free wire or stranded wires Mounting set available as an accessory Standards: EN 61558; EN 60601 Technical data Rated power 10 – 6000 VA Input voltage 230 V Output voltage 24 – 690 V Rated current max. 50 A Frequency range 50 – 400 Hz Temperature class T40/E and T40/B *In addition to these standard series, we develop special solutions with special voltages and higher outputs according to your requirements.
