THREE PHASE MOTOR STARTING AUTO TRANSFORMERS
Macro Power produces dry type auto-starter transformers to suit all motor capacities.
Motor starting transformers are auto transformers with tapings in the range of 50% to 100% of the rated voltage as per Australian standards AS1202 (or customer specified). The motor to be started is switched through the auto transformer in such a way as to start the motor at a lower voltage to minimise starting load and the associated supply voltage drop.
Long Service life (no maintenance, extremely high reliability )
Reliable performance (cool, quite operation –no fans or moving parts)
Rugged construction and conservative ratings
Tapped at 50%, 65% 80%, & 100% (other tapings available on request)
Ordinary Duty (3 starts per/hour, 15 sec. per start, Class 0.03)
Intermittent Duty (12 starts per/hour, 15 sec. per start, Class 0.1) 
Frequent Duty (30 starts per/hour, 15 sec. per start, Class 0.3)
Highest Insulation level - class ‘H’
Excellent regulation
High power density
Excellent load weight ratio
2 or 3 coil designs available 
Voltages ranging from 380 to 3.3 KV available
Normal open or closed thermostats or thermistors fitted. 
Installation:
Transformers must be protected by external devices such as Fuses, circuit breakers or thermal relay contacts.
Final 100% Testing:
High Voltage
Open Circuit Secondary Voltage
Voltage Ratio
Note: Due to continual product improvement data and specifications are subject to change without notice.
