Control Transformers

Control transformers with galvanic isolation are used for supplies of control systems with more than two consumers in accordance with EN 60204. Designed in accordance with VDE 0113, control transformers also provide continuous power in the event of short-term overloads. BLOCK's standard range includes power ratings of between 20 VA and 25,000 VA.

• Supply of control systems in accordance with EN 60204
• Control transformer in accordance with VDE 0113
• Power output: 20 VA to 25,000 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

Isolating Transformers

Isolating transformers with galvanic isolation provide a reliable supply to circuits with the safety measures “protective separation”. The transformers provide double or reinforced isolation between the primary and secondary sides. Any requested network configuration is possible for the secondary side, whether this involves a monitored isolated system or grounded system with fuse elements. The output voltage for the isolating transformers can be between 50 Vac and 1,000 Vac or 120 Vdc and 1,415 Vdc. BLOCK's standard range includes power outputs of up to 1 MVA.

• Double or reinforced isolation between the primary and secondary sides
• Flexible structure for the secondary side network configuration
• Power output: 50 Vac to 1,000 Vac or 120 Vdc to 1,415 Vdc
• Power output: up to 1 MVA, higher power ratings upon request

Applications

• As a safety isolating 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 an isolating transformer for the safe electrical isolation of the input and output sides. The transformer may be used to set up protective separation as a protective measure in accordance with VDE 0100.
• As a control transformer for the electrical isolation of the input and output sides. The construction of the transformer to supply control systems according to VDE 0113 is designed.
