Eaton introduces 48-volt DC/DC converter designed for harsh environments

2024-05-16 | 返回

SOUTHFIELD, Mich. – Intelligent power management company Eaton today announced it is now offering a higher power version of its low-voltage 48-volt DC/DC converter for commercial and off-highway vehicles that is designed to withstand the harsh environments in which those vehicles operate.

Eaton’s DC/DC converter takes power from a 48-volt system and steps it down to 12 volts to run accessories and other low-power systems. This design helps essential equipment—including antilock brakes and power steering—work even in the case of a power failure, making it unique among product offerings in this space.
There is a growing demand for 48-volt DC/DC converters as off-highway and commercial vehicle manufacturers increasingly switch to dual-voltage electrical architectures. Eaton’s converters feature a natural convection, air-cooled design for ease of integration and can operate at ambient temperatures up to 85 degrees Celsius. Additionally, the converters are designed with high efficiency to prevent power loss over a wide operating range.

The converters are also designed to reduce weight and save space. Most modern vehicles operate on 12-volts or 24-volts, so moving up to 48-volts results in up to four times the voltage, which decreases the electrical current by the same ratio. Because wire size is chosen based on the amount of electrical current, decreasing the current allows for the use of smaller wires, which reduces weight and helps alleviate packaging concerns.

Eaton’s DC/DC converter portfolio provides flexibility through multiple power and voltage levels and can be optimized to work seamlessly with a manufacturer’s charging system specifications. It also features a Controller Area Network (CAN) bus, which allows direct communication from the DC/DC converter to other vehicle electronic control units to transmit diagnostic information.
