Powersolve enhances UPS offering with versatile eight model PKR Series
Powersolve, recognised as a leader in power supply technology, has added to its uninterruptible power supply offering with the launch of the versatile PKR Series. The eight model PKR Series will satisfy a wide range of IT and Telecoms applications although Powersolve says PKR units can also be used in most back-up situations where constant and reliable power is required for short periods in the event of mains supply failure.
The An automatic bypass is incorporated into PKR units, which switch over to the incoming mains in the event of an inverter failure. Powersolve uses Yuasa high capacity NPW45-12 5 year life batteries as standard with 10 year life versions available as an option.
PKR Series UPS units use an online double conversion design normally found in more expensive units. The main advantage of an online UPS is the unit’s ability to provide an electrical “firewall” between the mains and the equipment it protects. In effect, it provides full protection against all manner of power quality issues as well as mains failure, with zero transfer time when switching to battery back up.
Although most users will specify the PKR supplies for 19in rack mount, they can also be used as stand alone tower units. A LED display indicates the unit’s status while and LCD display shows volts, frequency etc. Alarms alert users to UPS failure, low battery voltage and the presence of an abnormal mains supply while PKR Series units are protected against overload, over temperature and short circuit. Operating temperature range is 0 to 40ºC.
An intelligent RS232 communications port allows for remote management via UPS power management software or UPSilon 2000 and users also have the option of control using an external SNMP, USB or dry contact connection. Output is via IEC sockets or screw terminals depending on power rating.
