The SC903-031-01 is a servo drive by Pacific Scientific from the SC900 Servo Drives series. It operates on 90 – 264 VAC (47 – 440 Hz), delivers a 15 A peak output current for 5 s at 50 °C and 7.5 A continuous output current at 25 °C under convection cooling. With 96% efficiency, 15 J bus capacitance absorption, and a 20 kHz output current ripple frequency, it suits demanding industrial automation applications.

We used Servo Supplier to refurbish old drives and buy reconditioned parts. We received great and timely service at a fair price. I recommend them to anyone who has aging equipment and can't find support from their OEMs. Highly recommend.
Bostik Inc.
WE absolutely LOVE Servo Supplier. They are quick, efficient and friendly. Honest too, which is huge in our industry. We deal with many different companies, and these guys are tops in our humble opinion. There has never been an issue with delivery, no warranties, no hidden fees, no surprises. Just what you want in the manufacturing business. Smooth, and we love smooth.
Technomech Inc
First-time customer. The ordering process was completely seamless. The part that we ordered was at our business within 2 days. Which was excellent! We had a piece of equipment down for a little more than 48 hours. Could have been a lot longer had we purchased from one of our normal suppliers.
Steve T. from NF&M International
I found these guys online and needed a somewhat obscure part quickly, and they delivered! Very quick process from the time I requested a quote to the shipping of my items. Great work Servo Supplier team!

They were very quick to get the drive we needed shipped out to us. They were also very quick to respond and help with some pictures of information on the unit we ordered to ensure we received the right part.
Justin Ball from Miba
Understood our situation, and worked to help us get it solved. Very responsive, and stepped out to keep me informed until the product arrived. Exactly as described, and promised.
