Some suppliers have made the decision to review their product lines and have discontinued small DC Drives in their ranges. Pre-pandemic, a certain manufacturer took the decision to discontinue their range of larger DC Drives. Recently we are aware that a manufacturer has stopped production of their smaller DC drives.
Small analogue DC drives are still widely installed in numerous applications throughout the globe. Should an application be upgraded or a drive needing replacing our customers are advising that it is becoming increasingly difficult to source small DC drives.
This has been exacerbated recently by a major drives manufacturer rationalising their range and ceasing production of DC motor controllers below a certain rating. As well as Parker (also badged as SSD & Eurotherm Drives) discontinuing their small drives, Control Techniques had already taken the decision to stop manufacturing analogue drives some years ago. Sprint Electric DC drives have great alternatives to all of the discontinued drives and are available as low as 0.35HP / 0.25KW / 3.4A.
Whether you are looking to retrofit existing DC motor applications and finding that the drive has been discontinued or are sourcing a low-cost drive solution to control small brushed shunt wound and permanent magnet DC motors consider Sprint Electric DC Drives. There are low cost, open chassis-mount or DIN rail mounted DC Drives available. The open chassis-mount drives have been upgraded to include a cover and additional signal terminals to the top edge.
SPRINT ELECTRIC DC DRIVE EQUIVALENTS:
Parker 506 can be replaced with Sprint Electric 340i
Parker 507 can be replaced with Sprint Electric 680i
Parker 508 can be replaced with Sprint Electric 1220i
N.B. Sprint Electric replacement drives have comparable speed and current loops and if using one of the 340i, 680i or 1220i versions, have the advantage of slightly higher current plus the advantage that the drives are isolated.
Parker 512 & Parker 512C can be replaced with Sprint Electric 3200i [ Add link to product]
N.B. the max current for the 512/512C is 32A in Parker’s 8, 16 &32 versions whereas Sprint Electric’s 3200i is also built in 8, 16 & 32 versions plus the advantage of a higher current (48A).
Parker 514 & Parker 514C can be replaced with Sprint Electric 3600XRi [Add link to product ]
N.B. the 514/514C was built in 4, 8, 16 & 32 versions whereas Sprint Electric’s 3600XRi is also built in 4, 8, 16 & 32 versions plus a higher current, 36A version.
Control Techniques Puma can be replaced with Sprint Electric 400 [Add link to product ]
Control Techniques Cheetah can be replaced with Sprint Electric 1600i or 3200i
Control Techniques Lynx can be replaced with Sprint Electric 3200i
Control Techniques 4Q2 can be replaced with Sprint Electric 3600XRi
CONCLUSION
Replacement DC drives can always be found, even for discontinued drives. Sprint Electric DC drives are ideal as they are manufactured in UK, wherever possible using locally sourced parts guaranteeing quality and have availability from stock.
