Toroidal transformers only produce minimal leakage fields thanks to their shape. This means that the surrounding components remain free from interference. The transformers feature a very low design height and offer a crucial advantage as power, safety or isolating transformers in difficult installation conditions. With a space-saving wire connection, toroidal transformers can be soldered directly onto a PCB. BLOCK’s standard range includes power outputs of between 0.35 VA and 3,000 VA.
