Eaton introduces DC-DC converters for 48V industrial car architectures


Energy administration firm Eaton launched a household of 48-volt DC-DC converters for diesel-powered industrial autos that can be utilized to energy equipment comparable to antilock brakes and lighting. In contrast to aggressive choices, Eaton’s DC-DC converters are operational in ambient temperatures as much as 85 ˚C and boast 97% design effectivity.

DC-DC converters are an important a part of our eMobility product portfolio and are utilized in quite a lot of car purposes. Many industrial car producers are transitioning to 48-volt architectures, so being able to effectively convert energy from excessive to low voltage is essential. We’re delighted to ship power-conversion expertise designed particularly to satisfy the calls for of economic car electrical programs.

Eaton’s DC-DC converter takes energy from a 48-volt system and reduces it to 24 volts. The bi-directional unit then additional reduces the facility to 12 volts to be used in low-voltage programs and expenses a 12-volt battery that shops energy in case of a fault in the principle energy provide.

Eaton affords a household of DC-DC converters that adhere to Automotive Security Integrity Stage (ASIL) B useful necessities and might be optimized to work seamlessly with a producer’s alternator specs. The converters will also be tuned for particular responsibility cycles through superior digital management structure, enabling versatile management modes by firmware adaptation.

The DC-DC energy converter additionally options specialised high-power lock field (HPLB) energy connectors. The HPLB connectors are designed by Royal Energy Options, a number one producer of high-precision electrical connectivity elements that Eaton acquired earlier this 12 months.

The DC-DC energy converter’s HPLB terminals present superior effectivity and reliability in addition to safety towards the weather. Moreover, the HPLB terminals are waterproof as much as one meter deep and powerful sufficient to face up to high-pressure water spray.

Eaton’s DC-DC converter contains noise discount and rejection applied sciences, so the unit is unaffected by and doesn’t intrude with car electronics. Moreover, in contrast to aggressive applied sciences, the design effectivity of Eaton’s air-cooled DC-DC converters reduces energy loss over a large working vary, whereas the die-cast design contains a fin sample that delivers optimum thermal efficiency.

Business car 48-volt architectures additionally create the potential for the delicate hybridization of drive programs. Moreover, the upper energy programs can be utilized to energy electrified heaters to rapidly warmth a car’s aftertreatment catalyst to assist cut back emissions.
