About Knowtek AVR R220 Automatic Voltage Volt Regulator

AVR R220 Automatic Voltage Volt Regulator For Generator Alternator Genset   R220 AVR is used in LSA40 & LSA42.3 series alternators. The R220 AVR is a simple design, inexpensive and a perfect solution for small generators especially for standby or prime continuous applications.     For LSA 40 alternators.  Adapted to the SHUNT and AREP excitation system Main characteristics Voltage regulation +/- 0.5% at steady state and constant speed. Response time 500 ms Nominal excitation current : 3A Maximum excitation current 7A for 10 sec.   Features: Voltage supply/sensing range 85 to 139 V (50/60 Hz) Rapid response time (500 ms) for a transient voltage variation amplitude of ±  20% Voltage setting P1  Stability setting P2 Power supply protected by 8 A fuse, slowblow action (tolerates 10 A for 10 s) The fuse is impregnated in the resin, therefore it can not be replaced. Frequency: 50 Hz with ST3 jumper - 60 Hz without ST3 jumper. The size of the screwdriver tip used to adjust the potentiometer is 2.5 mm   Description: 1.R220 is an analog A.V.R. with numerical regulation function. 2.It is designed for small alternators with a SHUNT excitation. 3.It controls the excitation current in order to maintain the output voltage of the alternator. 4.It is performant in terms of voltage regulation,simple to set , to use and is reliable. 5.It is in compliance with I.E.C. 60034-1 standard and U.L. 508 / C.S.A. approved.   Technical specification Compatible with Leroy Somer Brushless generators bellow 100KW Power Input:35~ 109VAC 50/60Hz Exteral voltage adjustment:1 k ohm Voltage regulation:≤ ± 0.5% ...
