Rockwell Automation SA3000 High Power Modules - Manual (Page 55)

Technical Specifications A-3
Output Power
• Output Voltage: 575 VAC, maximum
• Modulation: Sine Wave, Pulse Width Modulation (PWM)
• Short Circuit Rating: 65 KA
• Power Dissipation: 534A Unit: 7500 W
972A Unit: 15000 W
1457A Unit: 22500 W
• Output Inductor: 7.5 µH per phase (972A and 1457A units only)
• Rail I/O Current Load: Power supply constraints dictate that any combination of
analog and digital I/O rails may be used as long as current
consumption does not exceed 1.5 A.
