The SR PF1 double conversion series with DSP technology, Digital Signal Processor, is the perfect solution for powering sensitive “mission critical” users who require reliability and performance from a static UPS. The correction of the input power factor, the unit power output factor and the high reliability provide a higher level of Power Quality for all sensitive electronic devices and safety devices such as IT, electromedical and industrial loads.
SINGLE PHASE ONLINE DOUBLE CONVERSION SINEWAVE UPS 6000VA – 10000VA RACK 19″, SR LCD PF1 SERIES
Description
In normal power supply conditions, the load is powered directly by the Inverter while the rectifier supplies the necessary power to the Inverter and to charge the batteries.
If one of the following conditions occurs on the power supply: interruption of the voltage, lack of a phase, voltage out of tolerance, the battery supplies the inverter with the necessary energy to supply the load without interruption. Once normal operating conditions are restored, the rectifier charges the battery and at the same time feeds the load through the inverter.
If one of the following conditions occurs: overload, Inverter output voltage out of tolerance, Inverter failure and overtemperature, the load is automatically transferred, without interruption, to the emergency network. Once normal operating conditions are restored, the load is automatically transferred back to the Inverter.

The front panel provides all the major parameters and the operating status of the UPS, which includes complete diagnostics and a simple user interface.
The UPS SR LCD PF 1 can be connected to other units of the same power by relying on the UPS control logics with a special accessory parallel kit, even after the first installation.
This functionality allows the UPS to work in redundancy, when the power required is less than the nominal power of the single UPS (n + 1), and the power parallel operation (2n) when, for peak current or greater power required, it exceeds the power of the single UPS. This operating selectivity is automatic and instantaneous. Up to 4 units can be connected in parallel, and are available as external manual by-pass accessories for parallel distribution up to 200A (40kVA).
Each UPS of the SR LCD PF1 series is equipped in standard configuration with a USB communication port, which allow connection with the software, supplied free of charge on request, for remote monitoring of the UPS status via PC.
Several optional interface cards are available for various communication requirements, RS232, RS485, dry contacts, SNMP/WEB card. All optional communication ports can be activated and used simultaneously for monitoring the status of the UPS; UPS control can take place via only one communication interface at a time (the one with the highest priority).
Emergency Power Off, the EPO terminal, located on the back of the UPS, uses a NO contact which, if closed, starts the shutdown sequence. Through a dedicated tool it is possible to configure it NC or it can be set up for remote start and shutdown.
– Additional battery cabinets to extend the autonomy of the UPS, even after the first installation.
– Additional 1000W battery charger. Its independent electronic control allows the accessory to work in parallel with up to four units in continuous service. It is designed to be connected on the back of the UPS.
– PDU, external manual by-pass. In addition to the internal manual by-pass available on request on the UPS, the external MTBP external by-pass, available in sizes up to 200A, connected to a single UPS allows a possible simple disconnection of the UPS without interruption, while in a compound system from several UPSs in parallel it has the centralized by-pass function for the exclusion and disconnection of a faulty UPS.
