Bravo

2.5kVA Hot-Swap Modular Inverter

Product Information

Bravo TSI 48/120 is a compact modular inverter that converts a 48VDC power source into 120VAC and provides a pure sine wave. By using several modules, we can offer solutions for two-phase (2 x 120Vac + N) or three-phase (3 x208VAC + N) infrastructures.

The extra AC input ensures a high overall efficiency (up to 95%) which results in a reduction of energy loss and heat dissipation.

This module has a modularity from 2.5kVA to up to 30kVA in order to be able to evolve with your needs. The hot swap feature makes maintenance easier and reduces the risk of errors.

The low ripple voltage avoids any disturbances on DC loads and batteries.

TWO YEAR WARRANTY
