ISKRA ALTERNATOR- 14V / 33A
NOMINAL VOLTAGE: 14V
NOMINAL CURRENT OUTPUT: 33A
MAXIMUM r/min: 12000 r/min
VOLTAGE REGULATOR: AER 1503
ROTATION (VIEWED AT PULLEY END): CLOCKWISE
NOTE: Pulley nut torque (1): 35-45 Nm
ISKRA 14V / 33A PERFORMANCE CURVE
The attached performance curve was plotted at a constant system
voltage
voltage of 13V and at an ambient temperature of 25°C.
NOTE: The rpm shown is reflective of an ISKRA alternator fitted to
an engine with a 88mm crankshaft pulley. The rpm shown is that of
the alternator rotor. Thus, at at an engine speed of 3600 rpm, the
alternator is turning approximately 4680 rpm, or a ratio of 1.3 :1.
