The Gruner 850 relay is the first relay for 48V applications in the automotive sector.
With the 852 relay, the 2nd generation of 48V relays is now available. 48V technology is used primarily in mild-hybrid vehicles for the management of lithium ion batteries. Due to their higher voltage, many functions in vehicles can be electrified without the additional weight of an extra battery. This enables the size of the engine to be reduced, which cuts down on CO2emissions.
The 852 relay is characterised by a higher level of power capacity. Here, a small controllable electronic unit is also integrated, together with an option for measuring and reading out the temperature on the contacts. 48V technology (MHEV) offers a cost benefit across the board: compared to plug-in-hybrids (PHEV) or fully electric vehicles (BEV), the system costs are relatively low.
