UniStar P Single-Phase UPS Features Parallelible On-Line Protection


Staco Energy Products Co. is pleased to introduce the UniStar P series single-phase online Uninterruptible Power Supply (UPS) which features powerful protection over a wide input voltage range at an affordable price. This true double-conversion UPS is available in 6, 8, and 10-kVA models, to protect from outages and irregularities in incoming line voltages from 160 to 280 VA at 45 – 65 Hz.    Up to 4 UniStar P modules can be installed in parallel for redundancy or additional capacity.   With near unity input power factor and AC to AC efficiency greater than 90% that meets industry standards for energy savings and, less than 5% reflected harmonics, the UniStar P is ideal for many industrial applications, as well as for servers and networks, telecommunications equipment, medical imaging equipment or any sensitive electronic devices.  

A constant clean, steady sine wave protects downstream equipment even without going to battery mode.   Each UniStar P features high overload handling without transfer to the bypass, and protection against short circuit and over-temperature conditions.  

The unique Smart Battery Management System continuously monitors battery status and recharges whenever necessary.  Hot swappable batter packs allow users to change batteries without shutting down the UPS, further simplifying maintenance.  Matching battery cabinets enhance the aesthetics of the UPS while providing easy access and maintenance.   

Available with capacities of 6 kVA, 8kVA and 10kVA, the UniStar P is easy to install, and monitor.  Easy to read front-panel LCD display includes input and output voltage, input and output frequency, load percentage, battery voltage and inner temperature.  Alarms are provided for line mode, backup mode, ECO mode, bypass supply, battery low, battery bad/disconnect, overload, transferring with interruption & UPS fault, line failure, battery low, transfer to bypass, and system fault conditions.  Each size offers remote monitoring and diagnostic capabilities through an RS232 serial port and optional web, USB, SNMP or Dry Contact Cards.  Standard software is compatible with operating systems such as Windows 98, 2000, ME, NT and XP.  For maximum installation versatility, it is offered in tower and rack-mount models.  

“We’re excited about this new technology because it offers users many advantages not typically found at such a favorable price point,” said Staco Energy Products Co. Vice President of Sales & Marketing Dave Kendall.  “Customers are no longer forced to choose between functionality and price – the UniStar P delivers both.  The ability to run in parallel for redundancy or extra capacity is huge and unique customer benefit.”
