Description
The RAC05-K series are ultra-compact AC/DC power supply modules in lightweight fully-encapsulated
plastic casing. Beside safety approvals for industrial and IT solutions IEC60950-1 and UL62368-1,
the units meet EN55032-“B“ limits without any external components. Integrated fusing as well as
electrical protections against short circuit and over voltage are on board. With their excellent efficiency
over the entire load range including light load standby conditions, these power modules are especially
suitable for IOT applications and control equipment.
