The Multi Sentry 20kVA/18kW uninterruptible power supply from Critical Power Supplies is an on-line double-conversion UPS with a built-in battery pack designed to give 14 minutes runtime at full load. The standard runtime can be extended using additional battery extension packs. The UPS has a three phase input and output.
Typical applications: Blade servers, comms rooms, server rooms and datacentres. Multi Sentry has a very high operating efficiency (94%), high input power factor, advanced battery management and can work in one of several operating modes: On-line, Economy, Smart active and Standby/Off, as well as operating as a frequency converter. Multi Sentry UPS have been designed for an easy install, especially on sites with limited power capacity available, a generator and harmonic compatibility problems. Low input current distortion less than 3%. High input power factor 0.99.
Power walk-in function to achieve progressive rectifier start-up. Delayed start-up on mains power supply return. Extended Runtime available upon request.
The UPS also acts as a high performance filter to protect its supplies from load induced harmonics and reactive power. Multi Sentry has a unique battery care system to optimise battery performance, extend working life and guarantee the UPS is fit to deliver its full-rated runtime when called upon to do so in the event of a complete mains power failure. The UPS is designed to operate with a range of battery types: VRLA AGM and GEL lead-acid batteries including open-vented types, in addition to Ni-Cads. Specific Battery Care features include. One-level recharge to meet the requirements of the most common VRLA AGM batteries. Two voltage level recharge meeting the IU characteristic. Restricted charging to reduce electrolyte consumption and extend the life of VRLA batteries.
Temperature compensation: to avoid excessive voltage being applied to the batteries in a high ambient. Built-in battery testing to enable predicted failure reports and detect performance degradation. Deep battery discharge protection: to prevent over discharging the battery set. Low AC ripple current, achieved using a high-frequency battery charger. Multi Sentry can be used for a wide range of applications with several customisation options and accessories providing flexibility and a choice of performance levels. Compatible with capacitive loads without any reduction in active power (0.9 lead to 0.9 lag).
Multiple operating modes: On-Line, Eco, Smart-active and Stand-By/Off and frequency conversion. PowerShare connections for priority-based load shedding on mains power supply failure. Cold-start facility to allow the UPS to be switched on even without a mains power supply present. Extended runtime options using battery extension cabinets.
Battery cabinet temperature sensor option to assist the temperature compensating charger. Larger battery charger options to optimize recharge times. Dual input supplies options for added resilience. Isolation transformer options for Galvanic isolation and neutral connectivity. 380/440/415Vac 3p+N, 50 or 60Hz (selectable).
Riello NetMan 204 Network Card. Compatible with 10/100 Mbps Ethernet and IP v4/6 networks. Compatible with PowerShield³ and TeleNetGuard. SNMP v1, v2 and v3 with RFC1628 for PowerNetGuard and NMS connection. SNMP v1 with RFC3433 for the management of environmental sensors. WiFi ready, using a customized dongle can communicate via WiFi network.
Events log and data management. Wake-on-LAN management for starting computers via TCP /IP network. Other standards: DHCP, DNS, FTP, NTP , ICMP , IGMP. Configurable via SSH sessions and HTTP. Firmware upgradeable via FTP and HTTP.
