1U military field-grade 3-Phase UPS delivers 1250W
SynQor has luanched a 3-phase balanced input military field-grade Uninterruptible Power Supply (UPS) with a 1250W capacity.
In addition to providing a glitch-free, continuous power to loads, the UPS-1500-S-1U-T also tackles the difficult problem of unbalanced loads on 3-phase systems in aircraft and ships. MIL-STD-1399-300B requires that all the phase currents be balanced to within ±5% for ships and ±3% for submarines. Achieving this high degree of phase current balance with today’s single-phase electronic loads is simplified with the UPS as it allows single hase loads to appear at the power source as a clean, well-behaved, nearly zero reactance balanced MIL-STD-1399-300B compliant 3-phase load. The UPS has a floating ground option for air or sea craft applications that might require that feature.
The 1U rack unit is designed to withstand the harshest and extreme electrical, shock/vibration and environmental conditions and can draw power from a 3-phase “Wye” or “Delta” connected AC source or from a 28 Vdc power source if equipped with the optional DC input port. The backup power of the system is provided by a hot-swappable sealed lithium polymer battery pack, and the whole unit weighs 15kg.
The single phase output of the UPS can be selected to be 115 or 230 Vrms at 50, 60 or 400 Hz with a maximum output capacity of 1250W/1500VA. The unit also has two optional ports, DC1 and DC2. The DC1 port can deliver several different voltages from 12 to 50 Vdc at 500 W. The DC2 port, if the UPS is not equipped with the DC input option, can deliver up to 1250 W of regulated or semi-regulated 24, 28 or 50 Vdc.
Additional options for the system include: a SNMP/Ethernet base module that allows real-time remote system monitoring with trap/email features that warn users and monitoring consoles of important system events; a 2U enclosure that increases battery run time from 10 to 24 minutes; a feature that allows wide dynamic input frequency range of operation (47-800 Hz) for variable frequency input AC applications; a droop share option that allows for load sharing of the DC2 output and a redundant (N+M) option that allows multiple UPS units to load share in either single phase, split phase or 3-phase configurations.
