Uninterruptible Power Systems 3 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 SolaHDs popular SDN Series of power supplies. SolaHDs 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. E137632 These units include easy to wire screw terminations for I.T.E. IND. CONT. critical devices needing battery back-up. The SDU DC UPS EQ 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 Features UPS will switch to battery back-up. If the battery is no longer Modular, rugged industrial grade design useful, the UPS will sound an alarm and an LED indicator will Microprocessor based controls illuminate. Automatic self-test feature for UPS function and battery Back-up power protection in modern industrial applications management check depends mainly on AC UPS. AC is converted to DC, and Power module wide operation temperature converted back to AC in the AC UPS, then converted range (-20 to +50C) back to DC in the protected equipment power supply. By ap- Flexible batteries back-up expansion capabilities plying the new SolaHD SDU DIN Rail DC UPS, you avoid the Overload protection in normal and battery modes inefficiencies of all these conversions. This design maximizes system up-time flexibility, and optimizes reliability assurance.
