Elsist UPS POLARIS 20kVA/18kW, Three-phase in/out On-Line double conversion, LCD, 10 min. autonomija, baterije uključene

– 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 Specifications
