  • Volume Discount
[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.
