SINGLE PHASE ONLINE DOUBLE CONVERSION SINEWAVE UPS 6000VA – 10000VA, NS LCD PF1 SERIES

The NS pf1 double conversion series with DSP technology, Digital Signal Processor, is the perfect solution for supplying sensitive mission critical utilities that require reliability and performance from an uninterruptible power supply. Input power factor correction, high efficiency and parallel redundant capability (N+X) provide a higher level of Power Quality for all sensitive electronic and safety devices such as electromedical.

Description

The backup series is composed by: Rectifier, Inverter, Static Switch, manual by-pass and Battery.
The Rectifier-Inverter line normally feeds the users, and the Battery is kept charged by the Rectifier.
If a black out occurs, the Battery supplies power energy to users always through the Inverter. When the blackout is over, the Rectifier provides for Battery charge.
If a short circuit or an overload occurs to the users, the Static By-pass switches the load over the emergency line. When the fault is over, the Inverter feeds users.

This feature allows up to no.4 UPS to operate in redundancy (N+1), when the required power is lower than the nominal power of the single group, and in power operation (2N) when exceeds the single UPS rated power due to peaks or greater power necessity. This operating selectivity is automatic and instantaneous. External manual by-pass accessories are available for parallel distribution up to 200A (40kW).

Each NS series UPS is equipped as standard with a USB communication port. This interface can be used with software provided free of charge for all major operating systems.

In addition to the standard equipment, the NS series UPSs can use, as accessories:

  • SNMP network interface with dedicated software;
  • RS485 interface;
  • RS232 interface;
  • Relay Contact Board
    (programmable by software for output relay)
    ;
  • Emergency Power Off (EPO) uses a NO contact which, if closed, starts the shutdown sequence. Also available NC if requested.

– Additional battery cabinets to upgrade the backup time till several hours even after the first installation. On request the add battery cabinet can be provided with an external independent battery charger to guarantee a fast recharge.
