Tehnička specifikacija

- POLARIS is a true on-line UPS, double conversion technology with high efficiency
- Input and Output voltages are three-phase
- High performance and high efficiency with PF 0.9 and PF 1 on demand
- POLARIS uses power modular technology and it works in redundance mode N+X
- It is a flexible system, in fact is possible to add or remove power cabinets depending by the amount of load to supply
- In this way it is possible to optimize the financial investments by escalating the configuration according to the real needs
- POLARIS can be used for any kind of load: IT, AUTOMATIC MACHINE, DATA CENTER, HOSPITAL, INDUSTRY, etc.
- POLARIS can solve every kind of problems, such as blackouts, spikes, voltage disturbances, frequency disturbances, harmonic distorsion (THD <2%), current noise, brownouts, surges, and so on
- POLARIS serie uses a Digital Signal Processor (DSP) control to increase the reliability, the efficiency, and for auto protection and auto diagnosis
- Polaris series keep input current balanced
- No unbalance problems may occur during the operation

Features
- True On-line UPS input three-phase + N, output three-phase + N
- Switching time 0 ms
- Power factor 0.9 - (optional PF 1)
- LCD display
- Modular power from 10kVA to 200kVA
- DSP (Digital Signal Processor)
- Input Low distorsion < 2%
- ECO mode function
- Optional: SNMP, MODBUS, RELAY. Standard: USB port, RS485, EPO contact

MODULAR POWER TECHNOLOGY
- Modular power technology used for POLARIS serie is an easy "Parallel concept"
- POLARIS serie has an intelligent sensor which automatically detects other UPSs with same power
- No settings via software, no parallel boards needed, UPS it is always ready and with a self test reset and adjust its output power
- Parallel control cables are shielded with double isolation to avoid noise interference
- The cables are connected in ring mode, as shown in the picture below. Ring connection is very reliable
- The parallel configuration guarantees an higher reliability than a single "Full power" UPS
- For making a correct configuration it is important to meet the items written below:
* 1) Every UPS must have the same power and connected to the same by-pass line
* 2) The electric cables (input, output, by-pass) must have the same length and same characteristics
