RAST 5
Power: 10.0 VA - 120.0 VA
RAST 5 Series of Sizes EI 48 to EI 84
The RAST 5 series comes with a user-friendly, flexible plug system for quick wiring according to VDE 0627/PM 906. This makes the assembly of individual modules much easier and can cut the time by up to two-thirds. The cable harness only needs to be plugged in on the primary and secondary sides. The previously necessary, time-consuming soldering, screwing, or tedious individual plugging is completely eliminated. Specially coded connectors with guide profiles ensure maximum mounting safety. Swapping the connection lines or plugs is absolutely impossible, even for beginners. The cable connections are made by machine, which also helps save costs.
The RAST 5 connection technology we developed for transformers offers manufacturers of electrical and household appliances convincing economic and safety advantages when assembling the devices.
