Powerbox IBC 050/048 VI Brick Intermediate bus converter series

Powerbox has released the latest additions to its IBC 050 and IBC 048 series of VI Brick Intermediate bus converters. The family already comprises over 12 models, in eighth- and quarter-brick formats, delivering from 300 to 750 W.

Offering pin-to-pin, drop-in functional equivalence to industry-standard converters, the devices enable designers to achieve increases in power density due not only to higher power ratings but also to PCB space liberated by the reduced need for external passive components.

The latest model is the IB050Q096T70N1-00, a high-power, 5:1 conversion ratio, open-frame drop-in replacement for intermediate bus converters. It operates from a wide input voltage of 36 to 60 at power levels of up to 750 W, with 2250 VDC isolation from input to output, while achieving over 98% peak efficiency. It delivers an output bus voltage of 7 to 12, while other family members with 4:1 conversion have outputs of 8.7 to 15 V. The family includes standard 38 to 55 V input range converters (IBC 048) as well as the wide-input IBC 050 types.

In all cases the modules are compliant with ETSI EN300 132-2 for 48 V telecom applications; and their higher input-to-output isolation complies with IEEE 802.3 power-over-ethernet standards. IBC 048 and 050 VI Brick devices use Vicor’s sine amplitude converter technology with a 1 MHz switching frequency, 10-times faster transient response, reduced harmonic emissions and elimination of external bulk storage capacitors.
