Magnetek GPD 503 Drive models11/16/2016The Magnetek GPD 503 is a high performance sine-coded PWM AC drive which generates an adjustable frequency three phase output for complete speed control of induction motors. Automatic stall prevention and voltage boost prevents unwanted nuisance trips during line side or load side transient conditions. The GPD 503 does not induce any line notching distortion back to the utility line. It also maintains a displacement power factor of not less than 0.95 throughout its entire speed range.The Magnetek GPD503 AC drive may be obsolete and not currently available new any longer, but it was a very popular and versatile drive in its day. One very common application in which these were used, was in Haas machines as spindle drives. These drives have also been widely used in several different elevator applications as well as HVAC applications.Many times when a customer calls in to find out our repair capabilities, we will provide a repair cost estimate based on the model they have. When the sales department asks for the model number, every now and then, the response is “GPD503”. However, this is the series and not the model. The actual model number for the drive usually begins with a “DS”.Some of the more popular models based on 230/240 volt input are:DS305 – 1HPDS302 – 2HPDS306 – 3HPDS307 – 5HPDS308 – 7.5HP There’s also a model 69-0800 for this size.DS309 – 10HP There’s also a model 69-0900 for this size.DS310 – 15HPDS311 – 20HPDS322 – 25HPSome of the more popular models based on 460/480 volt input are:DS313 – 1HPDS304 – 2HPDS314 – 3HPDS315 – 5HPDS316 – 7.5HP DS317 – 10HPDS318 – 15HPDS326 – 20HPDS325 – 25HPThere are also models that range in size much larger and with higher input voltages as well. These drives were manufactured by Yaskawa for Magnetek. In addition to the Magnetek GPD 503 drives, they were also branded and sold by other manufacturers as well. A few of these were the Yaskawa CIMR-G3 series, the Saftronics G3S series. Omron and IDM Controls sold them as the G3U series, and ElectroMotive Systems (EMS) sold them as the GPD503 series like Magnetek. These drives have some minor differences in the flashed firmware, but depending on the application in which they’re used, they are often interchangeable as long as a comparably sized drive is used. As mentioned previously, they are used by many HVAC manufacturers. The HVAC software option provides operational features that are available when the proper EPROM is installed.No matter what kinds of symptoms the drive is experiencing or the application in which it’s being used, Precision Electronic Services, Inc., has the experience and expertise servicing the GPD503 drives that you can rely upon to get the repair done right. So call us today at 800-732-4695. We will even save your parameters so that when you receive the repaired drive back at your facility, there will be no need to do any reprogramming. It’s ready to reinstall into the machine, power up and you’re back into production right away. Back To Blog
