INPUT RATINGS
Input Controls:
Contactors provide input ON-OFF control. An input circuit
breaker disconnects all input power from the cabinet.
Protection:
Meets National Electrical Code Protection requirements for
single phase, and reversed-phase rotation protection.
Voltage Transients:
Meets the Institute of Electrical and Electronics Engineers
587 requirements at 4000 V peak. Up to 150% line voltage
for ½-cycle.
Phase Rotation:
Unit will operate properly with any input phase rotation.
There are no input phase rotation sensitive devices.
Isolation:
An input transformer with an electrostatic shield provides
isolation between the input and output of the system.
Balance:
All three input phases are equally loaded regardless of
output phase load unbalance.
