Tripp Lites SmartPro Compact Rackmount Uninterruptible Power Supply (UPS) offers line interactive voltage regulation network grade surge suppression and long lasting battery support for critical network hardware during blackouts and extended power failures. Special reduced-depth housing larger internal batteries higher rated wattage and included 2 post rackmount installation hardware makes these systems ideal for network and telecom wiring closets and other limited-space installations. Runtime is expandable with optional BP48V24-2U (limit 1) BP48V60RT-3U (multi-pack compatible) and BP48V27-2US (multi-pack compatible) external battery packs.N/ASMART3000CRMXL 4U rackmount 3000VA UPS offers battery-derived sine wave AC output during power failures and extreme voltage variations. Supports 3000VA/2880 watts when powered via included L5-30P input plug. Supports up to 3600VA/3600 watts when hardwired to a 120V 30A input source. Line interactive Automatic Voltage Regulation (AVR) provides two levels of voltage boost during brownouts and one level of voltage cut during overvoltage conditions to maintain regulated 120V nominal output over an input range of 83-145V. Includes NEMA L5-30P input plug (or hardwire input) L5-30R and 5-15/20R output receptacles. Optional SNMPWEBCARD offers remote management and control of the UPS via direct network connection. Additional ENVIROSENSE accessory when used in conjunction with SNMPWEBCARD reports temperature humidity and status of up to two directly connected contact closure sensors. HID-compliant USB interface enables full integration with built-in power management and auto shutdown features of Windows and Mac OS X. Supports detailed monitoring of equipment load levels self-test data and utility power conditions via all 3 network interfaces at once. Includes PowerAlert monitoring software with USB and serial cables. Emergency Power Off (EPO) interface. Integrated 3-bank programmable PDU switching supports load shedding and remote-reboot of up to 3 individual connected devices. 3-stage metered current monitoring and battery charge status LEDs. Utility power and voltage regulation LEDs. Audible alarm. Self-test. 2-post rackmount accessories included; 2-9USTAND tower stands and 4POSTRAILKIT 4 post rackmount kit available. Field-replaceable hot-swappable internal batteries and external battery packs.
