Safety isolating transformer
ACT 25
Characteristics
General data
The safety transformers of the ACT series provide safe galvanic isolation of the primary circuit from the secondary circuit and are manufactured according to EN (IEC) 61558-2-6. By limiting the output voltage, the transformers are suitable for the construction of SELV and PELV circuits. The transformers feature a robust plastic housing and are designed for DIN rail mounting.
Benefits
› Integrated short-circuit and overload protection thanks to temperature fuse in the input and melting fuse in the output
› Permanent corrosion protection, high insulation value, and maximum electrical reliability thanks to XtraDenseFill resin encapsulation
› Perfectly suited for rail mounting, e.g., in small consumer units or meter mounting boards
