Application scenario
Application
Industrial control and automation cabinets
Supplies the 24V AC control rail for relays, contactors, timers, solenoid valves, PLC I/O modules and control boards inside machine and panel builds.
Power supply equipment
Acts as the mains-frequency step-down stage in front of the rectifier, filter and regulation circuits in linear power supplies, power adapters and DC power units.
Lighting equipment
Provides the 24V AC low-voltage supply for lighting fixtures and control gear, and handles step-down duty in lighting control assemblies.
Home appliances
Steps mains down to a low-voltage AC rail that feeds the rectifier and control board of household appliances, where a compact, low-heat transformer is required.
OEM / ODM and custom equipment
Transformer kits and custom chassis builds where input and output voltage, power rating, taps, shielding, lead length and mounting footprint are specified to the design.
