R250 A.V.R. FOR SHUNT ALTERNATORS
Description
Leroy Somer R250 is an analog A.V.R. with numerical regulation function (micro-controler) and power controled by transistors.
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
- 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
- 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
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
