SFL Series, 75–600 Watt
Power Supplies
The SFL series is a DIN Rail switching power supply series
that complements the SolaHD 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.
Features
• 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
• Adjustable output voltage
• Selectable input: 115/230 Vac
• UL1604 Listed for Class 1, Division 2 hazardous
locations (except -RED and -UDS versions)
• UL 508 Listed (except -RED and -UDS versions).
No derating necessary.
• Two year warranty
* Except 600 watt 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)
