The Murrelektronik 86345 is a single-phase safety transformer designed for industrial automation and applications requiring reliable, safe power conversion. It excels at converting 230V or 400V AC to a stable 24V AC with a 250 VA capacity, ensuring secure operation for sensitive equipment. While highly reliable, its IP20 rating means it is best suited for dry, protected environments.

Its primary function is to safely convert higher input voltages (230V or 400V AC) into a stable 24V AC output for use in control circuits and automation systems.
The transformer has a rated apparent power of 250 VA (Volt-Amperes).
No, with an IP20 rating, it is designed for indoor use in protected environments and should not be exposed to moisture or dust.
The transformer has an Insulation Class B, according to IEC 85, which specifies thermal endurance properties.
Yes, the Murrelektronik 86345 is designed as an isolating transformer, providing electrical isolation between the input and output circuits for enhanced safety.
No, you should connect either a 230V AC source or a 400V AC source to the primary terminals, not both simultaneously. Select the primary voltage that matches your supply.
Regular cleaning to remove dust and ensuring ventilation is clear are the main maintenance tasks. Inspect connections periodically.
Verify input voltage is within the specified range (230V or 400V AC). Check all connections for tightness. Ensure input fuses (if applicable) are intact. Test continuity of primary and secondary windings.
Ensure the load does not exceed the 250 VA rating. Verify that ventilation openings are clear and not obstructed. Check for short circuits in the connected load. Confirm ambient temperature is within operational limits.
Check input voltage stability. Reduce the connected load to ensure it is below the 250 VA capacity. Inspect connections for resistance or poor contact.
A low hum is normal for transformers. If the noise is excessively loud or changes pitch, check if the transformer is securely mounted and if laminations are properly secured.
