Each DCB3 Brake contains SCRs which have a minimum peak inverse voltage (PIV)
rating of two, and one-half times the line-to-line AC voltage. It also has a
root mean square (RMS) current rating normally selected to be three times the
full load continuous current to the motor.
DCB3 Brakes are rated to operate at the maximum DC current with a maximum ambient temperature of 40° C at an altitude of 6,500 feet (2,000 meters) above sea level.
Derating of one and one-half percent per degree C above 40° C and one percent
for every 330 feet (100 meters) above 3,300 feet, must be considered when
applying DCB3 Brakes. RECTIFIER 880AMP 1800V
