RS PRO 180 W Fixed Installation Car Power Adapter, 18 to 32 V DC/12 V DC The RS PRO 180 W fixed installation car power adapter safely reduces DC-DC power in vehicles. Using a switch-mode regulator, it takes input voltages of 18-32 V DC and converts them to 12 V DC. The adapter is protected by an aluminium case that's anodised to improve durability and heat dispersal. Colour-coded wires enable easy installation, while the dual-colour LED light makes identifying power status and failures simple. This unit is fitted with protection against overcurrent, overvoltage, overheating and short-circuiting. It's used in the automotive industry to prevent damage to vehicles and electronic devices.
