Energy administration firm Eaton launched a household of 48-volt DC-DC converters for diesel-powered business automobiles that can be utilized to energy equipment comparable to antilock brakes and lighting. Not like 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 a wide range of automobile functions. Many business automobile producers are transitioning to 48-volt architectures, so being able to effectively convert energy from excessive to low voltage is vital. We’re delighted to ship power-conversion expertise designed particularly to fulfill the calls for of business automobile electrical techniques.

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 techniques and fees a 12-volt battery that shops energy in case of a fault in the principle energy provide.
Eaton presents a household of DC-DC converters that adhere to Automotive Security Integrity Degree (ASIL) B purposeful necessities and could be optimized to work seamlessly with a producer’s alternator specs. The converters will also be tuned for particular obligation cycles by way of superior digital management structure, enabling versatile management modes by means of 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 yr.
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 resist high-pressure water spray.
Eaton’s DC-DC converter consists of noise discount and rejection applied sciences, so the unit is unaffected by and doesn’t intrude with automobile electronics. Moreover, not like 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 includes a fin sample that delivers optimum thermal efficiency.
Industrial automobile 48-volt architectures additionally create the potential for the delicate hybridization of drive techniques. Moreover, the upper energy techniques can be utilized to energy electrified heaters to rapidly warmth a automobile’s aftertreatment catalyst to assist cut back emissions.
