1. Leroy Somer Automatic Voltage Regulator R250 2. Suits leroy somer brushless alternator 3. Analogic Automatic Voltage Regulator with transistor 4. Applications Alternators LSA 42.2, 43.2, 44.2, 46.2, 47.2. Compatible with the SHUNT excitation system. The R250 is in Compliance with: IEC, VDE, NEMA, BS, CSA, UL508 low voltage. 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%. Voltage regulation: Approximately +/- 0.5% Working range: 85 to 139 V Voltage setting potentiometer: 1000 ohm/0.5W minimum setting range +/- 5% Operating frequency at 50 Hz: threshold at 48 Hz without LAM rating Impact between 30% and 40% of load Threshold is 48 Hz, LAM is 13%, used for rated Impact between 40% and 70% of the load. Threshold is 48 Hz, LAM is 25%, for rated load with shock more than 70% Operation at 60 Hz: 58 Hz threshold, no LAM pair Influence between 30% and 40% of rated load The threshold is 58Hz, and the LAM is 13%, used to shock 40% and 70% of the rated load Threshold is 58Hz, LAM is 25%, used for rated load with shock more than 70% Specific operation: 57Hz threshold, no LAM, speed change in steady state more than 2 Hz 65Hz threshold, no LAM, for speed and traction/gear (U/F gradient) 47.5 Hz threshold, no LAM, for steady-state speed changes more than 2 Hz colour: black Material: plastic Package Contents: 1 x Voltage regulator Only the above package content, other products are not included. Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
