Editor's Notes
- Efficiency indicates how well a UPS system converts input into output (Efficiency = Output Power ÷ Input Power). The higher the efficiency, the more the UPS system will save in operating costs. Tripp Lite SmartOnline High-Power, offer two levels of efficiency for two levels of cost savings. When the UPS is in Economy Mode, its inverter is not feeding the load during normal operation (saving energy). When needed (during a blackout, for example) the inverter will automatically connected to the load. When the UPS is in Online Mode, its inverter is continuously on. The difference between the two modes is a matter of user preference according to the level of protection needed.
- THDi (Total Harmonic Distortion - input) is distortion generated by a UPS System that is "reflected" back through the input to the utility or generator source. All 3-Phase UPS Systems, regardless of the manufacturer, generate some level of THDi. If the THDi is high, managers are forced to oversize everything that distributes power to the UPS: generator, distribution panels, cables, etc. If managers install a UPS that generates lower THDi, they can save significant installation costs. Tripp Lite's Modular 3-Phase UPS Systems provide lower THDi than competitive models, dramatically lowering installation costs. With Tripp Lite's Modular 3-Phase UPSs, managers can match the kVA of their generator to the kVA of their UPS (referred to as 1:1 sizing or "generator-friendly design"). With competitor's UPS models, managers often have to double the size of their generator to compensate for higher THDi (referred to as 2:1 sizing). With less distortion reflected back through the input, managers can install lower gauge cables and lower-rated circuit breakers. Tripp Lite Modular UPSs also lower installation costs through better parallel capability. All models are parallel-ready, eliminating the need to upgrade from non-parallel to parallel models. In addition, the UPSs feature a non-proprietary parallel distribution scheme. Users can deploy their own or a Tripp Lite distribution panel, whichever is more cost-effective and convenient.
- Efficiency refers to how well the UPS converts input power into output power (and the amount of power the UPS consumes in order to operate). Tripp Lite Modular 3-Phase UPS Systems are up to 97% efficient. Since they consume less energy to operate, they save electricity costs. Also, since they consume less energy, they generate less heat, reducing facility cooling and airflow management costs. Tripp Lite Modular 3-Phase UPS Systems feature two levels of efficient operation: Economic Mode (up to 97% efficient) and On-Line Mode (up to 94% efficient). In Economic Mode, the UPS features line-interactive operation, automatically switching to on-line operation only when needed. In On-Line Mode, the UPS features continuous on-line operation. The difference between the two modes is a matter of user preference according to the level of protection required. Another way Tripp Lite Modular 3-Phase UPSs lower operating costs is through the widest voltage correction range in its class. The benefits of voltage correction are very simple: the more abnormally high or low input voltages the UPS corrects on its own, the less it has to rely on its batteries. This helps batteries last longer and reduces the number of times they need to be replaced. Tripp Lite Modular 3-Phase UPS Systems correct the widest range of input voltages in the industry without relying on the battery. Tripp Lite models correct undervoltages as low as 25% below nominal input and overvoltages as high as 20% above nominal input. Typical competitors' models only correct undervoltages as low as 10% below nominal input and overvoltages as high as 15% above nominal input. The advantage of Tripp Lite's superior voltage correction is dramatic, with up to 40% less potential battery wear!
- Tripp Lite Hot-Swap Modular UPS Systems provide greater availability than other types of UPS Systems typically installed in network applications. All UPS types support equipment during a power failure because they feature battery backup support. Line interactive UPSs will not support equipment during an internal fault, because they do not feature an internal auto bypass. Line interactive and typical online UPSs will not support equipment during UPS repair, because they do not feature an external manual bypass switch and a detachable PDU. Only Tripp Lite Hot-Swap Modular UPS Systems provide continuous availability through every application scenario.
- Our NH series can do all levels of redundancies to suit the 4 tiers of Data Centers up to 60KVA load For the above example with 60KVA load (instead of 200KVA): N: By using SU60Kx N+1: By Using SU80Kx (where an extra PM is available in the UPS for redundancy) 2N: By using 2 x SU60Kx (connected in Parallel) 2(N+1): By using 2 x SU80Kx (connected in Parallel)
- NH models of 380V models feature two AC inputs. Tripp Lite provides all of the equipment needed for parallel applications, with the exception of the primary and redundant distribution panels. Depending on the UPS model, the External Battery Modules pictured above also may not be required. SU20KX and SU40KX models feature internal batteries and do not require an External Battery Module to function. All other UPS models do not include internal batteries, and, therefore, do require connection of the external battery module (included as a standard feature). The parallel connection procedure is as follows: 1) wire UPS inputs to distribution panel(s); 2) wire UPS outputs to parallel tie cabinet; 3) Connect parallel communication cable between UPSs; 4) wire parallel distribution panel output to load. Parallel Connection Warnings: The total input cable length must be equal to the total output cable length in order to prevent unbalanced load sharing between two UPS systems under reserve mode. The maximum number of UPSs that can be connected in parallel is two. Do not attempt to parallel more than two UPS systems. The UPS systems must have the same rating and capacity for parallel redundancy installation. Attempting to link dissimilar UPS systems will damage the UPS systems and create a serious risk of personal injury and property damage.
- Tripp Lite’s SU1000RT3UG UPS System features an external manual bypass switch and a detachable input/output power distribution unit (PDU). When the switch is set to "bypass", the UPS’s power and battery modules can be removed for maintenance while the detachable PDU module remains installed, continuing to power connected equipment as long as utility power is present. These unique availability features are in addition to an automatic internal bypass that ensures 100% availability of connected equipment by passing through utility power in the event of an internal fault or overload.
