Connector size range• flexible cable• solid cable• Wire strip length

Design details – for your advantage:• All terminals are easy to reach as mounted on the front panel.
• Input and output are strictly apart from each other (input below, output above) and so cannot be mixed up.
• Mounting and connection do not require any screwdriver• A jumper (output terminal) serves to adjust the output voltage(12V resp. 15V).
