RAST 5
Power: 10.0 VA - 120.0 VA
RAST 5 series in sizes EI 48 to EI 84
The RAST 5 series are equipped with a user-friendly, variable plug-in system for quick wiring in accordance with VDE 0627/PM 906. This considerably simplifies the installation of the individual assemblies and shortens it by up to two thirds. The wiring harness is only plugged in on the primary and secondary sides. The previously necessary and time-consuming soldering, screwing or time-consuming individual plugging is no longer necessary. Specially coded connectors with guide profiles ensure maximum installation safety. It is absolutely impossible to mix up the connecting wires or plugs, even for inexperienced users. The cable connections can be produced by machine, which also reduces costs.
The RAST 5 connection technology for transformers developed by our company offers electrical and white goods manufacturers convincing economic and safety prospects for appliance assembly.
