Power Transformers

Power transformers with galvanic isolation can be used, e.g., to supply reliable low contact voltage to FELV circuits. In accordance with EN 61558, 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.

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

Safety Transformers

Safety transformers with galvanic isolation provide a reliable supply to power circuits with the safety measures “protective separation” or “protection through shutdown”. Double or reinforced isolation between the primary and secondary sides protects SELV and PELV circuits. Safety transformers provide safety extra low voltages below 50 Vac or 120 Vdc. BLOCK's standard range includes power ratings of between 0.5 VA and 2,500 VA.

• Protection for SELV and PELV circuits
• For safety extra low voltages below 50 Vac or 120 Vdc
• Power output: 0.5 VA to 2,500 VA

PCB Transformers

PCB transformers are vacuum molded and feature a very high proof voltage as a result. Used on the PCB, they provide electrical isolation as a power transformer or safe electrical isolation for the input and output sides as an isolating or safety transformer. BLOCK's wide range of standard solutions provides the ideal supply for your circuit, from PCB transformers offering absolute or limited short-circuit protection or ones that are not short-circuit proof.

Applications

• Safety transformer for the safe electrical isolation of the input and output sides. The transformer is suitable for creating SELV and PELV circuits because of the limit on the output voltage.
• As a mains transformer for adjustment of the voltage and simple electrical isolation.
