Safety isolating transformer **FL 42/12** ## Advantages Minimum size at high output Low height Dual input voltage for series or parallel connection Dual output voltage for series or parallel connection Permanent corrosion protection, high insulation value and maximum electrical reliability thanks to XtraDenseFill resin encapsulation Self-extinguishing potting material ## Applications As a mains transformer for adjustment of the voltage and simple electrical isolation. 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 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. ## Sample application **==> picture [79 x 6] intentionally omitted <==** **----- Start of picture text -----**<br> Picture shows FL 42/12<br>**----- End of picture text -----**<br> ## Standards Z Safety isolating transformer to: VDE 0570 Part 2-6, DIN EN 61558-2-6, EN 61558-2-6, IEC 61558-2-6, UL 5085-1/-2, CSA 22.2 No.66 ## Approvals W 2 w Z VDE, UL 5085-1/-2, CSA 22.2 No.66 ## Safety isolating transformer **FL 42/12** **==> picture [524 x 247] intentionally omitted <==** **----- Start of picture text -----**<br> Type FL 42/12 Type FL 42/12<br>Input Terminal and mounting<br>Rated input voltage 2 x 115 Vac Terminals Pins for PCB<br>Rated frequency 50 - 60 Hz Measures and weights<br>xe)@oO |——SsS—COsSsSCSCtsssssSSSsS—<—s—S OutRated output voltageput 2 x 12 Vac xe)PF?|) A Core typeWeight UI 48/170.72 kg<br>85CcoO Rated PowerNo-load voltage (app. x factor)No-load loss (typ.) 42 VA1.163.50 W §Cco 6.5 -) 0.5 x 1.0 _—_ 15.0<br>Efficiency 81.0 %<br>§ Standards [>S 27.0 i aes S 37.0<br>10.0<br>Classification Safety isolating transformer 15.0 PRI SEC 60.0<br>Approvals (| 70.0 0.03.1 39.0<br>Approvals cURus, VDE (O tSO}<br>a a a<br>Environment 53.5<br>Ambient temperature max. 40 °C = 75.083.5<br>Safety and protection<br>Type Encapsulated<br>Insulation class VDE=E, UL=class 105<br>Protection index IP 00<br>Safety class (prepared) II<br>Short circuit strength non-short-circuit proof<br>Order numbers<br>Order Number FL 42/12<br>30<br>- +<br>**----- End of picture text -----**<br>

About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
