SPM3A Rev.3

The keen alternative to the SPM3


• The SPM3A is a compact measuring device in the lower price
   segment designed for the measurement of ripple control pulses in
   the mains net.
• It measures the maximum pulse value and the pulse length.
• The SPM3A is additionally designed for the continuous
   measurement, e.g. of the 5th mains harmonic (250Hz).
• Furthermore the SPM3A can be used with the SPM3 Software or the
   SPM3Rec (Data Logger) for the graphical recording of ripple control
   transmissions in the mains.
