Features :

• Thyristor control 

• Good regulation ±2% from no load to full load at 0.8% 

• Response time 1.5 sec. or better, if suitable forcing margins are allowed in the machine. 

• Under frequency roll of circuit to protect against over excitation at low frequency (speed). 

• Adjustable stability control. 

• Large safety margins allowed on rating of all semi conductor devices and protection against surges. 

• Silicon devices through out the regulator provide satisfactory operation even at high ambient temperature up to 50șC. 

• Terminal voltage of the alternator can be varied manually by ±8%.
