Ripple Control Test Transmitter SRScontrol


Acrobat-Logo  SRScontrol data sheet

The portable transmitter used for receiver testing

The portable test transmitter SRScontrol serves as a test station for ripple control receivers of any kind. Together with a PC it can create all conventional ripple control telegrams and newer telegrams such as Swistra and Versacom.
In addition, the PC operating software provides the ability to process switching schedules and programming of receivers to check for proper receiver parameterisation.


• Generating all common ripple control telegrams and their specific pulse grid
• Enabling / disabling of switching programs, changing of switching times and weekday activation of the switching programs in intelligent ripple control receivers
• Direct connection of up to 10 receivers at the output, supply voltage 100-265 VAC and ripple control signal
• Adjustable ripple control signal level in the range of 0 – 25 V
• Adjustable ripple control frequency in the range of 100 – 2000 Hz
• Digital inputs and outputs with 5 V signal level, not isolated
• USB interface for configuration and operation
• Optional: Built-in voltmeter to measure the output voltage

Frequency Output Voltage

The output voltage generated by the SRScontrol can be selected in the range of 100 VAC to 265 VAC. Thus receivers of various supply voltages can be tested. The test transmitter creates a synthetic network with potential harmonics and interfering frequencies which is completely independent and isolated from the supply voltage. Disturbances and influences of the supply voltage thus have no effect on the measurement result.
In addition to the 50 Hz voltage the SRScontrol can simultaneously generate up to three different harmonics with up to 25 V signal levels. Moreover, another freely selectable and triggerable external disturbance frequency can be added. Hence, receivers can be tested under various network conditions.
All standard tests according to DIN EN 62054-11, section 7.6.11/12/13 can be executed automatically (software option). Also interruptions in the supply voltage (in multiples of 20 ms) are possible.

Digital Inputs and Outputs

20 digital inputs (5 V signal level, not electrically isolated) are available to report back switching actions of the receiver. It is hereby possible to execute an automated test scheme. Alternatively, any digital input can also be used to process an external keying signal, e.g. from a ripple controller.
The 4 digital outputs (5 V signal level, not electrically isolated) are freely programmable.
The in- and outputs are accessible through a 25-pin parallel interface.
