SFL Series, 75-600 Watt Power Supplies

The SFL series is a DIN Rail switching power supply series that complements the Sola SDN products with more input voltage, output voltage and power levels to give an even broader range of industrial DC power solutions. These products are available in 12, 24 and 48 VDC output and 115/230 VAC Input. They feature pluggable screw connectors (mating connectors are included in each box sold) for easy installation and service. The products feature a DIN Rail connection, front panel DC OK indicators, easily accessible AC and DC connections.

For parallel operation with power sharing, a redundant module option is available for the 300 W (24 V/12 A) and 600 W (24 V/24 A) models.


  • DIN Rail Mount regulated switch mode power supplies
  • 12 V, 24 V, and 48 V outputs available from 1.5-24 A
  • Easy-to-wire pluggable and screw terminal connectors
  • Output voltage adjustable
  • Selectable input: 115/230 VAC
  • UL 508 Listed (except -RED versions). No derating necessary.
  • UL1604 Listed for Class 1, Division 2 hazardous locations (except -RED versions)
  • Fully Integrated Redundant and Remote Control Options:
    • RED (for SFL24-24-100 and SFL12-24-100 only): Designed for N + 1 redundant power supply systems, these units provide active current sharing and allow up to 5 power supplies to be paralleled. Decoupling diodes and an alarm output to signal a unit failure are included in this option. Multiple units are required for redundancy.
  • Models with optional battery back-up available:
    • UDS (for SFL24-24-100 and SFL12-24-100 only)
