SMA7130, SMA71075 and SMA71100 MANUAL
• Frequency response 750 Hz minimum.
(Velocity Loop):
• Frequency response 2 KHz minimum.
(Current Loop):
• External A separate input is provided to reset the amplifier after a fault.
fault reset:
• High-Speed Electronic Instantly shuts down the amplifier in the event of a short across
Circuit Breaker outputs and or ground fault condition.
(HS/ECB):
• Low-Speed Electronic Shuts down the amplifier if the amplifier is operated above the
Circuit Breaker maximum continuous current rating for 2 seconds.
(LS/ECB):
• Over/under voltage These circuits constantly monitor amplifier power-supply
and over temperature: voltages, and amplifier-heatsink temperature. They will shut down the
amplifier in the event of any out-of-specification amplifier condition.
• Surface mount Constructed with surface mount components.
technology:
• Line operated AC power operation, 110-130VAC: Single or three phase AC input with in-rush current
protection at turn-on. No power isolation transformer is required.
• Regen clamp circuit (shunt regulator) with LED indicator and internal load resistor bank bleeds off excess
DC Buss voltage when decelerating a large load inertia (95 watts for the SMA7130 and 375 watts for the
SMA71075 and SMA71100). The regen clamp circuit is set to turn on at 225VDC.
• All faults can be monitored through isolated logic signals.
• Bridge rectifier(s) and filter capacitor(s).
• Cooling fans.
