Power Supplies
SFL Series, 75–600 Watt
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, and easily accessible AC
and DC connections.
For parallel operation with power sharing, a redundant
version is available for the 300 W (24 V/12 A) and 600 W
(24 V/24 A) models.

• Fully Integrated Redundant models available:
- 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)
