General Description of DSR Mecc Alte Automatic Voltage Regulator AVR For Generator

The DSR is a voltage regulator for synchronous alternators, designed for stand alone working and calibration; to maximize performance, the regulator should be understood as part of a system made up of at least three components: the DSR (control unit), a communications module (USB2DxR, for example) and a supervision unit, as illustrated in figure 5.
The connectors for connection to and from the power generator and communications module are located on the DSR regulator.
The supervision unit can be made up of a personal computer, another “synoptic” device or both; it does not have the function of controlling the system in real time, but allows programming and visualization of all operational parameters of the DSR.
If it is equipped with a USB interface, for its connection it is possible to use the communication module USB2DxR.

Technical Specifications

  • Full digital controlled regulator, based on DSP
  • On-board machine installation
  • Suitable for all self-regulated alternators
  • Voltage supply: 40Vac÷270Vac (from auxiliary winding, output voltage or PMG)
  • Frequency range: 12Hz ÷ 72Hz
  • “Sensing” of voltage with true RMS or average measurement (70÷280 Vac)
  • Maximum continuous output current: 5Adc;
  • Precision of voltage regulation: ± 1% from no-load to nominal load in static condition, with any power factor and for frequency variations ranging from -5% to +20% of the nominal value.
  • In order to avoid damage to persons and/or property, only qualified personnel, having full knowledge and understanding of the information contained in this manual, should perform the procedures described herein; when power to the unit is on, the voltage present may be lethal for the operator.
  • All connections must be made with the power off.
  • The plastic protections on connectors J1 and J2 must not be removed for any reason whatsoever.
  • Instruction Manual DSR digital regulator – rev. 08 – pag. 5
  • Precision of voltage regulation: ± 1% from no-load to nominal load in static condition, with any power factor and for frequency variations ranging from -5% to +20% of the nominal value.
  •  Transient power drops and overvoltage within ± 15%
  • Voltage recovery time within ± 3% of the value set, in less than 300 msec.
  • Transient overvoltage during start up: less than 5% of nominal voltage.
  • Single phase sensing
  • Parameters: VOLT, STAB, AMP and Hz can be set with trimmers (default) 50/60Hz through a “jumper” (default); all parameters can be programmed via software.
  • Analogical remote control of output voltage is possible through external voltage (0÷2,5Vdc) or with a 10 Kohm linear potentiometer.
  • Environmental temperature: -25°C ÷ +70°C
  • Under speed protection with adjustable threshold and slope
  • Underexcitation alarm / loss of excitation (4)
  • Excitation overcurrent protection with delayed intervention
  • Management of temporary short circuits (start up of asynchronous motors)
  • (Non-isolated) Open collector output signalling the intervention of protections with a configurable activation for individual alarms, possibility to delay the intervention and selectable active level.
  • Abnormal operation conditions storage (type of alarm, number of events, duration of the last event, total time)
  • Memorization of the regulator operation time (starting from revision 11 of the Firmware)
  • USB communication interface (with an optional USB2DxR module)
