Celestica Adds QUS20-120/HUS42-096 Converters
Celestica Inc. (Toronto, Ontario) announced the expansion of the company's IBC Series isolated dc-dc converters with the QUS20-120 vertical-mount, quarter-brick model and the HUS42-096 half-brick model. With a wide input-voltage range of 36 V to 55 V, the HUS42-096 achieves high efficiency levels of up to 97%, and is rated at 460 W. In an industry-standard, half-brick outline, the HUS42-096 is available in both positive and negative enable logic models, and can be used in parallel for an even higher output power. With dimensions of 2.3 in x 2.4 in x 0.45 in, the HUS42-096 has a power density of 185 W/in³.
The QUS20-120-NVDR, which is the vertical-mount 4:1 fixed ratio quarter-brick version of the QUS20-120 IBC Series product line, takes up 1.08 in² of board space while achieving the efficiency and current thermal de-rating of the QUS20-120 Series converters. With dimensions of 2.5 in x 0.38 in x 1.25 in, the QUS20-120 converters offers high efficiency levels of up to 96%, and is available in both positive and negative enable logic models. The converters can also be used in parallel for higher output power requirements.
The QUS20-120-NVDR and HUS42-096 are available now. Pricing at 1,000 units ranges from $39 to $78 based on model and output voltage.
