Safety isolating transformer
SIM 300
Characteristics
General data
The safety transformers of the SIM series ensure safe galvanic isolation of the primary circuit from the secondary circuit. The transformers are manufactured according to EN (IEC) 61558-2-6 and have a protection class of IP 20. By limiting the output voltage, the transformers are suitable for the construction of SELV and PELV circuits.
Benefits
› Integrated short-circuit and overload protection
› Dual output coils for series or parallel connection
› Excellent moisture protection and low noise emission thanks to XtraDenseFill resin encapsulation
› Screw terminal connections under cover with strain relief
