. Suitable for all Mecc Alte self-regulated alternators
. Power connections through 20 poles(1) Fast-On connector (see fig.2)
. Protection of power winding with 5A fast acting fuse
. Signal connections (Pext, 60Hz Jumper, APO) through 10 poles mini Fast-Onseparate connector
. Environmental temperature: -25"C t +70"C
. Voltage supply: 40Vac+270Vac (2)(from auxiliary winding, output voltage or PMG). Maximum continuous output current: 5Adc
. Frequency range: 12Hz-72Hz
. Three phase or single phase sensing in all connections (Y-แบž-YY-8)
. Single phase or three phase sensing automatic recognition
. Average value of voltage regulation
. Voltage regulation range (sensing) from 75Vac to 300Vac
. Precision of voltage regulation: t 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.. Precision of voltage regulation: t 0,5% in stabilized conditions (load, temperature).. Transient voltage drop and overvoltage within t 15%
. Voltage recovery time within t 3% of the value set, in less than 300 msec.
. Programmable Soft start
. Parameters: VOLT, STAB, AMP and Hz settable by trimmers (default), 50/60Hzsettable by a "jumper" (default), all parameters programmable via software
.0+2,5Vdc or -10: +10Vdc external voltage for analogical remote control of outputvoltage
. Remote control of output voltage through external potentiometer (from 25Kohmto 100Kohm)
. Underspeed protection with adjustable threshold and slope
. Overvoltage and undervoltage alarms
. Excitation overcurrent protection with delayed intervention
. Underexcitation alarm/loss os excitation(6)
. Management of temporary short circuits (start up of asynchronous motors). Open collector output (not insulated) signalling some allarm intervention withprogrammable activation in respect of each alarm and possibility of the intervention delay and selectable activelevel(6)
. Allarm conditions storage (type of alarm, number of events, duration of the lastevent, total time)
. Memorization of the regulator operation time
. USB communications interface (with optional USB2DxRmodule)
