IP54 devices - splash-proof power supply for the highest standards

For water-cooling and decentralised appliances without cabinets, we have developed the splash-proof series IP500 and OB900 from the HEVW platform . The 8 mm thick aluminium flange is also suitable for the connection to a heat sink or a large wall surface (OB900). The devices are intrinsically safe and switch off in case of thermal overload. This enables higher power outputs than the permanent load described in the data sheet.


A peak load of 1400 W can be kept up for 10 seconds. Apart from normal power supply unit applications, we can also integrate battery chargers into the depicted housings. The round design has been developed particularly for flanging motors in on-board units. As a special solution, we can also integrate multiple voltages into the design.
