Adjusters
The is a voltage regulator for 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 (control unit), a communications module (DI1, for example) and a supervision unit, as illustrated in figure 4 or 12.
The connectors for connection to and from the power generator and communications module are located on the 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 visualisation of all operational parameters of the .
If it is equipped with an RS485 or RS232 serial interface, the DI1 communications module is necessary for its connection.
FEATURE
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: 4Adc;
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.
