LCR120 ripple control receiver

The compact LCR 120 is a high-quality and modular ripple control receiver. It can be used in standard ripple control applications as well as in modern systems with „Distributed Intelligence“ (VERSAOM) as a remotely programmable tariff switching unit. It is equipped with one relay for 40 A, a second for 6 A nominal switching current, and can be installed on a DIN-rail or with an additional cover on a wall.

The operation of the internal clock during a power failure can be secured for a few days from a built in supercap (option).

  • Digital filtering of the ripple control signal through the microcontroller
  • Processing of all conventional ripple control protocols and its specific pulse patterns and of a second protocol with secured data transmission according to DIN 43861-301 (VERSACOM)
  • Remote parameterisation of switching times and weekday assignment of the work schedules (using the VERSACOM-protocol)
  • Internal clock (remotely synchronizible) for autonomous operating of work schedules (weekday based)
  • Storage of pulse pattern and signal level of the last received telegram
  • Nominal switching current:  R1 = 40 A, R2 = 6 A
