Control power transformers

Control power transformers with galvanic isolation can be used, e.g., to supply reliable low contact voltage to FELV circuits. In accordance with EN 61558, control power transformers provide basic isolation between the primary and secondary sides at a minimum. This makes them ideal for creating new independent networks. BLOCK’s standard range includes power ratings of between 0.5 VA and 2,500 VA.

Overview:

◼︎ Basic isolation in accordance with EN 61558
◼︎ Power output: 0.5 VA to 2,500 VA
