Uninterruptible Power Systems
SDU Series, Direct Current Uninterruptible Power Supply (DC UPS) System
The SDU DIN Rail DC UPS is an advanced 24 Vdc
uninterruptible power system that combines an industry
leading design with a wide operational temperature range
and unique installation options. The SDU DC UPS is a
powerful, microprocessor controlled UPS that provides
protection from power interruptions. With an input voltage
range of 22.5 to 30.0 Vdc, the DC UPS is the ideal power
back-up solution for your critical connected loads.
These units were designed specically for use with SolaHD’s
popular SDN Series of power supplies. SolaHD’s external
battery module is the only one on the market that allows you
to seal the electronics in the panel and maintain safety by
placing the battery outside of a non-ventilated enclosure.
These units include easy to wire screw terminations for
critical devices needing battery back-up. The SDU DC UPS
includes an automatic self-test feature that checks the UPS
and battery functions. Battery charging occurs automatically
when input DC power is applied. When power fails, the DC
UPS will switch to battery back-up. If the battery is no longer
useful, the UPS will sound an alarm and an LED indicator will
illuminate.
Back-up power protection in modern industrial applications
depends mainly on AC UPS. AC is converted to DC, and
converted back to AC in the AC UPS, then converted
back to DC in the protected equipment power supply. By
applying the SolaHD SDU DIN Rail DC UPS, you avoid the
inefciencies of all these conversions. This design maximizes
system up-time exibility, and optimizes reliability assurance.

There are three individual hardware products when putting
an SDU DC UPS system into operation:
1. 24 Vdc Power Supply (Recommended SolaHD
SDN Series)
2. 24 Vdc SDU DC UPS Power Module
3. 24 Vdc SDU DC UPS Battery Module; or
24 Vdc SDU DC UPS External Battery Module
There are two models of the SDU DC UPS Power Module:
1. SDU 10-24, 24 Vdc/10amp (battery modules are
required)
2. SDU 20-24, 24 Vdc/20amp (battery modules
are required)
DIN Rail Mounted Battery Option
There are two models * of the SDU DC UPS Battery
Modules:
1. SDU 24-BAT, DIN Rail/Panel mount for installation in
ventilated enclosure, up to 4 battery modules can be
connected to the SDU DC UPS.
2. SDU 24-BATEM, Panel mount, alternate battery module
for external installation of non-ventilated enclosures, only
1 battery module can be connected to the SDU DC UPS.
* Can not use a combination of both models of the battery modules, only
one model of the battery module can be connected to the SDU DC UPS.
