FAQ
Can the TKA30A-C be used to derive 5V power for embedded control boards from a 9-18VAC source?
Yes, the published input range is 9-18VAC and the output is constant 5V. With a 25W rating and 3.5A output current, it fits 5V embedded boards that stay within those limits.
Is this converter appropriate for 5V logic or communication modules in industrial equipment?
It is suitable when the source available is 9-18VAC and the module requires regulated 5V output. The unit is rated for 25W total and up to 3.5A output current.
Can I use the TKA30A-C for 5V automation electronics that need constant-voltage output?
Yes, constant-voltage operation is one of the published product specs. It provides 5V output from a 9-18VAC input source, with 25W power and 3.5A output current available.
Is the TKA30A-C practical for small-format industrial assemblies?
The listed size is 50.8 x 50.8 x 21.0 mm and the weight is 0.11 kg, so it is compact for embedded or panel-level assemblies. Electrically, it is intended for 9-18VAC input systems needing constant 5V output up to 25W.
Can this model be used in very cold or very hot operating conditions?
The specified operating temperature range is -40°C to +85°C. That supports a broad indoor temperature range, but the provided specs do not include an IP rating for outdoor exposure or liquid ingress protection.
What is the published difference between TKA30A-C and TKA30A-B?
The sibling data provided shows both models with the same published ratings: 25W, 5V output, 3.5A output current, and 9-18VAC input. Both are also listed at 50.8 x 50.8 x 21.0 mm, so the provided specs do not indicate an electrical difference.
