19'' rack-mount uninterruptable power supply (UPS)
2 - 3 kVA | TN380R
TBB POWER
Combined with modern semiconductors with high switching frequencies provides compact construction, low weight and very high efficiency. TN380R modular UPS was specially designed for Utility and Power Gen application utilizing the 220VDC battery assisted DC system. It features a real sinusoid, stable output voltage in static or dynamic conditions. A smart digital control technique allows very fast response time to any load variation as well as good overload capabilities.
It is a truly redundant modular UPS, by which can be composed into a N+1 redundancy system. This function is totally self-determined without need of additional controller. In case of a faulty master, a new master will be selected automatically and loads are uninterrupted.
Single modules are hot plug design which make the maintenance an easy job without interruption to your critical load. Meantime, it make the system power expansion possible and convenient.
