Control transformer, Isolation transformer, Safety transformer

BLOCK

[Specifications]
・Frequency(Hz): 50 - 60
・Insulation class: VDE = B. UL = class 105, VDE = B. UL = 130, VDE = B. UL = class 130, B, E

[Features]
・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.
・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 40 VA and 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 0.35 VA and 2,500 VA.

PCB mount transformer

BLOCK

[Specifications]
・Product type: PCB mount transformer
・Frequency(Hz): 50 - 60

[Features]
・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
・Minimal design size with high power output
・Double input and output voltage for series or parallel connections
・Power output 0.35 VA to 52 VA

Auto transformer

BLOCK

[Specifications]
・Product type: Autotransformer
・Frequency(Hz): 50 - 60
・Ambient temperature (max.)(°C): +40

Autotransformers are the efficient and ideal solution for minor voltage adjustments. Compact designs can be provided depending on the voltage difference. Autotransformers feature lower losses compared with isolating transformers with the same power rating. The transformers without galvanic isolation also feature inverse operation.

[Features]
・Efficient solution for minor voltage adjustments
・Inverse operation possible
・Power output: 150 VA to 250,000 VA
