    3.2 GENERAL CHARACTERISTICS 3.2.1 Output Types The RTDW can operate with three types of output converters: DCU, DDU or Direct. By default, the system used is the DCU, allows a more precise and effective control of the consumer voltage. 3.2.1.1 DCU Converter (Default Configuration) The DCU system is based on the use of a DC/DC converter to regulate the output voltage.
  • Page 14 Note: This circuit is disabled in RTDW models that have positive or negative terminals grounded. The RTDW has electronics with dual power supply and a supervisory system that operate redundantly, providing even greater protection to the consumer's power supply in case of failure.

  • Page 15: Output Parallelism

    If it is desirable to determine how each rectifier will operate: taking full load or remaining in standby, it is possible to adjust the output voltage of the individual DCU in each RTDW. To do that, it is necessary to maintain a voltage difference greater than three volts in relation to the other rectifiers in parallel.

    Note: The Supervisory System is only available on models with DCU. Operation When an event that compromises the specified output voltage occurs, the RTDW activates the bypass and connects the rectifier/battery to the consumer’s output. The Supervisory System is composed of two output voltage protection levels: the first one by means of the control itself, and the second one via dedicated circuit, ensuring even more robustness to the RTDW.
