Prostar ET20K LV 3 phase 208v double conversion 20kva industrial ups system helps maintain your enterprise-wide networks, data centers, mission-critical systems and industrial manufacturing processes.
ET LV 208V three-phase uninterruptible power supply delivers top performance for edge, small, and medium data centers, as well as critical infrastructure in commercial and industrial facilities. Its compact design, high-density technology, N+1 redundancy, and fault-tolerant architecture maximize availability, operational efficiency, and critical load protection, while minimizing total cost of ownership.
Best 3 phase 208v double conversion 20kva industrial ups system is up to seven percent more efficient than other UPSs in its class, helping to keep your operating costs down.
A manual bypass breaker as well as an automatic bypass function ensure 100% availability of connected equipment by safely passing through AC power if the UPS requires maintenance.
20KVA UPS Features & Benefits
1. Wide input voltage range and frequency range
Designed for harsh electrical environments to save battery life, and suitable for fuel generators or other power generation equipment.
2. Most advanced and high frequency DSP technology
High input power factor, advanced IGBT inverter technology and Digital Signal Processor (DSP) technology create low input Total Harmonic Distortion (THDi).
3. Super overload capacity
Long-time working under the load of less than 105%; switching to the bypass in 10min under the load of 105% (inclusive) to 125%; switching to the bypass output in 1min under the load of 125% (inclusive) to 150%.
4. Multi-communication Interface
It offers RS232, USB, RS485, CAN, NET, input and output dry contacts, SNMP board, WIFI board, GPRS board and 4G board to monitor the operating status of UPS.
5. Parallel-redundant capable
Power the connected equipment with multiple uninterruptible power supplies to increase system redundancy and share the common battery packs to reduce the cost.
6. Dual mains input
Increases availability by allowing the UPS to be connected to two separate power sources.
7. Cold start and mains start without battery
In the abnormal state of the utility power, the UPS can be started directly with the battery to meet emergency needs.
There is no battery, the UPS can be started directly from the mains power.
8. Lithium-ion batteries compatible
It must be set up separately, not included in the standard configuration.
