Differing hardware features
Version Description
SK 5xxE-…-CP
compared with SK 5xxE
• ColdPlate or external heat sink
SK 5x5E
compared with SK 5x0E
• External 24V supply voltage. Communication with the frequency inverter is
possible even without a power connection
For size 5 and above in
comparison with sizes 1 –
4 (> 4 kW, 230V or
> 11 kW, 400V)
• Additional, separately mounted PTC input (potential isolated)
• External 24V supply voltage with automatic switchover to the internal 24V low
voltage generator on failure of the external control voltage.
• Processing of both bipolar and analog signals
• 2 x CANbus/CANopen interfaces via RJ45 plug as standard
