The Liebert Super 400D is a True on line sine wave UPS system that provides the user with clean computer grade power for continues operation of his critical load, regardless of any disturbance on the UPS stream AC power. The System offers many innovative features to give the user maximum reliability and flexibility at the lowest operating cost. With Liebert Super 400D UPS System, You have complete peace of mind.

ICBT Rectifier
Employing the latest rectifier technology, the Super 400D IGBT rectifier offers an input power factor of greater than 0.99, and input current distortion of less than 5%. Therefore it does not pollute the input utility supply or other devices sharing the same utility source.
ICBT Inverter
High speed IGBT inverter gives low output distortion and clean sinusoidal waveform for excellent performance and high reliability.
Digital Signal Processing
The Super 400D uses the most advanced DSP technology. Using high sampling rate possible only with DSP, the system parameters are tightly controlled and maintained throughout the various modes of operation.
Battery Management
Proper testing, charging, discharging and management of the battery system is a very important aspect of the UPS control system. In the Super 400D UPS, the batteries are constantly monitored by an intelligent battery management algorithm.
Paralleling Capability
The Super 400D can be paralleled for redundancy. The units can also be installed in a Hot-Standby configuration for added reliability and flexibility.
Wide Input Voltage Range
The Super 400D features a wide input voltage range which can accept upper input limit of + 15% and can have a lower input limit of - 25%, while still maintaining the specified output stability. This is extremely useful in very poor input power supply situations as the battery energy is not utilized I and can be preserved for more prolonged outages.
Reverse Phase Sequence Operation
In a situation where the Input phase sequencing is not consistent (any change in phase sequence), the UPS automatically adjusts itself and gets synchronised with the Input phase. This feature prevents the battery energy thereby improving backup time and life of the battery.
