 SFL
Series, 75-600 Watt Power Supply
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.

(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.
