Transformer PVS 230V/24V for screw fastening
Tufvasson
Transformer PVS 230V/24V for screw fastening
Art. no.: 5204052
Protective transformer according to EN 61 558 in class II for use in isolation or an inefficient insulated system where U = 50V alternating current. The transformers are designed with safety separation between the primary and secondary windings and intended for the supply of SELV and PELV circuits. The transformers are CE-marked and meet the applicable LVD and EMC requirements and insulation requirement class III that are 4kV.
Transformers are nested within the cover of the light grey UV resistant self-fading thermoplastic and fitted with plastic bushings > IP44, breakout openings < IP40.
The secondary voltage varies linearly with the load and the nominal voltage is indicated in the event of 100% load, the transformer must never be overloaded, but can cope with a temporary start current of 300% for 10 s.
The transformer is intended for use in appropriate areas such as supply voltage of the actuator control, thermostats, light and sound signals.

Safety transformer Type LF-GS 230-250/12 V stationary IP44
Noratel
Safety transformer Type LF-GS 230-250/12 V stationary IP44
Art. no.: 5202070
1-phase transformer, in design in accordance with EN61558-2-6. Compact, robust construction for industrial applications that is resistant to moisture, dust and vibrations. Low noise level. Embedded in self-extinguishing polyurethane with external cover made of plastic. Class ll, double-insulated. Short-circuit-proof and protected against overload with glass tube fuse and a built-in "one cut" thermal fuse. Surface mounting fixing holes for permanent installation. Connection to screw terminals easily accessible under cover. Cable glands and details cable relief are included upon delivery. The output voltage can be regulated by means of connection to terminals for 230 or 250V on the primary side. CE certified. Application areas: Power supply for control and regulation equipment, locking and alarm installations, heat foil or - cable, halogen lighting and other installations for extra low-voltage (power supply to SELV and PELV circuits). For fixed installation.

Safety transformer Type FR 230-250/24 V encased IP20
Noratel
Safety transformer Type FR 230-250/24 V encased IP20
Art. no.: 5202302
1-phase transformer, in design in accordance with EN61558-2-6. Class II, double-insulated. The FR series is based on modern production methods and developed to meet increased requirements for reliability and service life. It is completely cast in self-extinguishing polyurethane with an outer cover of plastic, providing a robust design that withstands vibrations and other mechanical stresses and protects against dirt and moisture. Designed for a 45°C ambient temperature and meets the requirements of DNV. Earthing connection not needed, as the transformer is double-insulated. Standard FR must be protected against overloading and short-circuit with an external fuse.
Application areas:
All FR series transformers are intended for installation in control cabinets. FR-60B, FR78B and FR-84B can be directly installed on a 35mm DIN rail. Often used for power supply to contactors. The plastic enclosure is vibration-tested by Det Norske Veritas for marine applications. No extra covering for the transformer is normally required when installed in a control cabinet. Special designs on request.
