the small receiver for big EEG-applications

Acrobat-Logo  SReeg data sheet

The SReeg is a state-of-the-art, Swistra-compatible audio-frequency ripple-control receiver which has been specifically designed to meet load management tasks.

It  is  particularly well-suited for pacing (e.g. of photovoltaic systems etc.) in accordance with the EEG, the Renewable Energies Act.

The SReeg offers a total of 4 relay contacts which can switch control currents
(max. 2 A / 30 VDC  or 0.2 A / 230 VAC or max. 60 W), in an only 35 mm small DIN rail case.

Gold-clad twin contacts guarantee a maximum reliability – even for low voltages and low currents.

  • Unit dimensions in accordance with DIN 43880 for DIN-rail mounting in accordance with DIN EN 60715
  • Unit width 35 mm
  • Suitable for „installation space for tariff control units“ in electricity-meter cabinets
  • 4 relays 230 V / 0.2 A NO contact (also programmable as NC contact)
  • Surge-proof relays up to 4 kV in accordance with IEC 60060-1
  • Position indicator for relays and display of functions via LED
  • Suitable for all commonly-used, conventional ripple-control telegrams
    (incl. DIN 43861-301)
  • Clock timer function with 48 h power reserve (optional)
  • Grid-wide (isochrone), secure clock time synchronisation better than 10 msec
  • Optical interface in accordance with IEC 62056-21 for parameterization, analysis of ripple-control signals and evaluation of protocols
  • Optional lead-sealable cover  for terminal cover which can be used when not installed in sealed installation space
  • Optional Swistra-functionalities
  • Special feature:  gold-clad twin contacts

All Swistec ripple-control receivers use state-of-the-art, recently developed filter algorithms that can even reliably process ripple-control signals with operating voltages below
0.3 % Un, a result of state-of-the-art processor technology that combines high processing power with low power consumption.
