Encapsulated in a robust, DIN-rail mount metal housing, every module includes three LEDs, and at least one signal output status LED (varies per model). Wago Corp.'s free configuration and monitoring software is bundled with the 787 Series UPS Controller for convenient custom configuration, diagnostics and monitoring. The 787 Series UPS is said to be the only one of its kind that provides both an LCD/keypad and RS-232 interface. Under normal operation, the UPS controller charges the 787 Series battery. During an outage, the UPS controller engages the battery, preventing data loss. In addition to free software, the UPS Controller operates at 95 percent efficiency and boasts an operating temperature range of -10 C to +60 C. During shorter power interruptions such as brownouts, the 787 Series buffer module protects data. The 787 Series redundancy modules safeguard two power supplies that are parallel-connected to provide system redundancy or additional power. www.wago.com
