Mitsubishi Electric’s 9900B UPS is a three phase, online double-conversion system, featuring IGBT technology for enhanced UPS performance and reliability.

The 9900B UPS delivers all-around dependability, with 97% efficiency in double conversion, a small footprint, capacitors with a 15-year design life, distributed bypass design for multimodule operation, low heat rejection to save on cooling costs, industrial fans, and ease of maintenance via front access to pull-out trays.

Mitsubishi Electric’s 9900B has a sustained load carrying capacity of 99.9995% of actual operational history.

The 9900B is one of the data centre industry’s first UPS with three-level IGBT topology delivering optimum control and performance, utilizing a combination of high sampling rates and Direct Digital Control (DDC). The IGBT power device for the 9900B UPS achieves superior function under all load conditions.

The 9900B UPS is Lithium Ion, VRLA, VLA, and Pure Lead compatible for greater flexibility.
