It is designed for small alternators with a SHUNT excitation. R250 Leroy Somer AVR controls the excitation current in order to maintain the output voltage of the alternator. R250 AVR is performant in terms of voltage regulation, simple to set , to use and is reliable. It is in compliance with I.E.C. 60034-1 standard and U.L. 508 / C.S.A. approved. Operation mode : Standalone Main feature and characteristics of Leroy Somer AVR R250 Voltage Regulator - Voltage regulation : ± 0.5 %. - U/F function. - LAM function. - Quick response : 500 ms. - Nominal excitation current : 5A - Maximum excitation current : 7A during 10 s. - Provide range / voltage detection : 85 to 139 V (50/60Hz). - Protection : fuse 8A. Operation conditions of Leroy Somer R250 Voltage Regulator - Operating temperature range : - 40° C à + 65° C. - Storage temperature range : - 55° C à + 85° C. - Hygrometry : 98%. - Maximum choc : 9 g on 3 axis. - Vibrations : less than 10 Hz , 2 mm peak magnitude. From 10 Hz to 100 Hz : 100 mm/s, below 100 Hz : 8g. Connexion and setting for Leroy Somer R250 Generator AVR Settings are done through the A.V.R. - Potentiometer P1 : voltage setting. - Potentiometer P2 : stability setting. - Strap ST3 : frequency selection. - Jumper : frequency, U/F function, LAM function - Potentiometer ST4 : remote voltage setting. Package List: 1 * Voltage Regulator The manufacturer's name and model number are for reference only and are not products manufactured by the manufacturer. R250 AVR controls the excitation current according to the alternator's output voltage. With a very simple conception, the shunt excitation alternator is auto excited with a R250 and excitation alternator does not have a short circuit capacity, voltage regulation: around ±0.5%. Power Input Voltage:120(90-140)VAC,1 phase 2 wire Magnetic Field Output Voltage:max 100VDC at 120 VAC Input Magnetic Field Output Current:continuous 8A intermittent 10A within 10 seconds Pressure Regulating Accuracy <+/-1% RMS with 4% engine governing
