Radio volume regulator RHR 01

Application and function

The REGONIK RHR 01 Radio Volume Regulator (attenuator) is designated for the regulation of the volume of the programme channel of the REGONIK VRZ 11 Train Radio Appliance which meets the demands of the UIC 568 international standard.

The REGONIK RHR 01 regulator is an active 12 -position switch, which produces 10-grade direct control voltage (“CONTROL”) at the output for VCA in REGONIK RZW 11, RZW 12, RZW 13, RZW 14 and RZW 15 Controlled Power Amplifiers. With the coming of the PRIOR signal for forced listening, the output voltage reaches the maximum level. Step changes in control voltage have smooth transition with a long enough time constant to ensure a pleasant switching of the volume without any interference in the whole range of regulation. In the OZW 11, OZW 15 compartment power amplifiers, the RHR volume regulator is integrated into the common unit together with the power amplifier.

Properties and technical parameters:

  • operating supply voltage 16V to 32V DC
  • max. input without load of 0,5W
  • maximum ripple of operation supply voltage of 8Vpp
  • output voltage with 11 levels from 1,85V to 6,5V
  • 12 position switch without end position
  • range of input low-frequency voltage for active PRIOR of min.2,0V and max.32V
  • protection against short circuit at the output
  • protection against polarity reversing of battery up to 80V
  • increased resistance against damage
  • insulated shaft of the switch with a length of 40mm can be shortened if required PVC button of the switch can be ordered as needed(recommended D16x20 ÷ 60mm)
  • operation temperature -30°C to +60°C
  • dimensions h=120, w=75, d=40 without the shaft of the switch
  • mass of 0,3kg without accessories
