November 1, 2013 – Staco Energy Products has introduced the FirstLine PL—a parallelable three-phase uninterruptible power supply (UPS) for 10-40kVA applications, boasting efficiencies of up to 94% for lower energy costs and reduced carbon footprint.

The 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, says the company. All units—which can be set for 50/60Hz frequency conversion—are intended for applications with input voltage of 208 VAC, three-phase, 4-wire plus ground, or 220V.
