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 specifically 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 inefficiencies of all these conversions. This design maximizes
system up-time flexibility, and optimizes reliability assurance.
