Staco Energy Introduces 3-Phase Uninterruptible Power Supply

Published:2011/12/8 4:28:00 Author:Amy From:SeekIC

Staco Energy Products Company releases the addition to the new 65kVA model FirstLine P family of parallelable three-phase Uninterruptible Power Supplies (UPS). Designed in response to the demand for a lower kVA version of native 480VAC product family, this unit is up to 98% efficient. The product features upstream filtering of harmonics and reactive load emanating from the powered load. With flexible installation options available, up to 8 units can be run in parallel.

Through IGBT and Digital Signal Processor (DSP) control, true on-line, double-conversion technology is achieved, and enables delivery of a high input power factor of 0.99, and a low input current distortion of less than or equal to 3%.

Up to 8 FirstLine P units (N + 1) can be run in parallel, providing redundancy for mission critical applications. All units are hot swappable. The FirstLine P requires only front, top or bottom access, so it can be placed against a wall, minimizing its footprint. Battery run times are best in class.

With IGBT-based rectifier solid-state technology, it reduces the impact of the UPS on the local supply and simplifies installation. Classified as a “Zero Impact Source”, the FirstLine P provides a high input power factor of 0.99, a low input current distortion of less than or equal to 3%, and a 0power walk-in function that ensures progressive rectifier start-up.

FirstLine P models feature an output transformer with galvanic isolation to provide greater versatility and installation options. The UPS can be supplied from two separate power sources which can increase the resilience of single or parallel system configurations.

FirstLine models are intended for applications with input voltage of 480 Vac and a range of +15 /- 20% without battery contribution. Input frequency is 45-65Hz. Progressive rectifier (walk-in) can be configured from 0 to 30 seconds. Delay of progressive start of rectifier (Power Walk-In delay timer) can be configured from 0 to 120 seconds. The entire FirstLine range of products is compatible with capacitive loads such as blade servers, without any reduction in active power, ranging from 0.9 lead to 0.8 lag and up to 0.8 capacitive power, with a low derating equal to 15% of the active power (kW).

A user-friendly menu selectable display located on the front of the unit includes an alarm, emergency power off button, and LED indicators for bypass, main line, battery powering the load, load on bypass, and normal output. Communications options include NetMan 101/102 Plus, MultiCOM (1) 301/302, MultiCOM (2) 362, Multi I/O, IBM AS/400, NetMan, MultiPanel, PowerShield, and PowerNETGuard. Battery Racks, Power Distribution Units (PDU) and Static transfer switches (STS) are available to meet virtually any application. The two year on-site warranty covers parts and labor (start-up service required for warranty coverage). Field service programs – including preventative maintenance – are available to lower cost of ownership.

Multiple options which allow the FirstLine P to be tailored to specific site requirements include isolation transformer, synchronizer device, parallel systems joiner device, interface for generator set, and a closed loop kit.
