Recently, some suppliers have reviewed their product lines and decided to discontinue small DC drives. Even before the pandemic, one manufacturer had already stopped producing their larger DC drives. More recently, another manufacturer also halted production of their smaller DC drives.
However, small analogue DC drives are still widely used in many applications worldwide. But when it comes to upgrading or replacing drives, customers are finding it increasingly challenging to locate small DC drives.
Adding to this challenge, a major drives manufacturer recently made things more difficult by streamlining their range and halting production of DC motor controllers below a certain rating. Parker (also known as SSD & Eurotherm Drives) and Control Techniques had already discontinued their small and analogue drives, respectively.
Fortunately, Sprint Electric offers excellent alternatives to all discontinued drives. They provide options starting as low as 0.35HP / 0.25KW / 3.4A. So, if you’re looking to retrofit existing DC motor applications or seeking a cost-effective solution for controlling small brushed shunt wound and permanent magnet DC motors, Sprint Electric DC Drives is worth considering. They offer low-cost, open chassis-mount or DIN rail-mounted DC drives. Plus, the open chassis-mount drives now come with a cover and extra signal terminals on 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
Note: Sprint Electric replacement drives feature comparable speed and current loops. If you use the 340i, 680i, or 1220i versions, you’ll benefit from slightly higher current and the added advantage of drive isolation.
Replace the Parker 512 and Parker 512C with the Sprint Electric 3200i. Note that while the maximum current for the Parker 512/512C is 32A in their 8, 16, and 32 versions, the Sprint Electric 3200i offers the same versions plus a higher current option of 48A.
Parker 514 & Parker 514C can be replaced with Sprint Electric 3600XRi
Note: 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
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
You can always find replacement DC drives, even for discontinued models. Sprint Electric DC drives, made in the UK with locally sourced parts whenever possible, guarantee quality and are readily available from stock.
