Product Overview

The SDU 20-24 is a direct current Uninterruptible Power Supply (DC UPS) 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 30VDC, 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. 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.
