Parallelable Double-Conversion 3-Phase 10-40kVA UPS Boasts 94% Efficiency

September 19, 2013 by Jeff Shepard

Staco Energy Products Company introduces the FirstLine® PL – a parallelable three-phase uninterruptible power supply (UPS) for 10-40kVA applications. These units boast efficiencies of up to 94% for lower energy costs and reduced carbon footprint, while delivering maximum availability and flexibility. Compact and reliable, internal batteries allow a smaller footprint, while cooler operation extends internal component life. True on-line, double-conversion technology is achieved through IGBT and DSP control, enabling delivery of a high input power factor of 0.99, and a low input current distortion of less than or equal to 1% at full load. All units can be set for 50/60Hz frequency conversion; - 0 models can operate as a precision power conditioner which is upgradable to a UPS in the future.

FirstLine® PL models are intended for applications with input voltage of 208 VAC, three-phase, 4-wire plus ground, or 220V. Input frequency is 45-65Hz. As a standard feature, up to 4 FirstLine® PL units can be run in parallel, providing redundancy for mission critical applications or additional capacity, requiring no additional hardware. FirstLine® P requires only front, top or bottom access, minimizing its footprint. Battery run times are best in class.

SNMP and MOD-BUS communication, and paralleling circuit are all standard. Each UPS is covered by an industry-leading 2-year warranty and backed by a nationwide service program with optional preventive maintenance to lower cost of ownership. The compact and reliable FirstLine ® PL is ideal for information technology (IT) applications such as computer rooms, and network closets, as well as broadcast studios, assembly/manufacturing lines, medical facilities, and other applications where a high level of available power and backup power are essential.

The IGBT-based rectifier solid-state technology reduces the impact of the UPS on the local supply and simplifies installation where there is limited power capacity in the form of available electrical supply rating or generator size, the FirstLine® PL provides a high input power factor of 0.99, a low input current distortion of less than 1%. It also performs as a high performance filter by protecting upstream power supply sources from any harmonics and reactive power generated by the loads power.

FirstLine® PL models can be supplied from two separate power sources (main power and a second emergency standby source) which can increase the resilience of single or parallel system configurations. Advanced control with Adaptive Feed Cancellation (AFC) cancellation technology ensures low harmonic distortion.

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 Monitoring and Shutdown Software with SNMP Agent. Extended Battery Cabinets and Power Distribution Units (PDU) to match are also available. The two year on-site warranty covers parts and labor (start-up service required for warranty coverage). Field service programs – including preventive maintenance – are available to lower cost of ownership.
