FAQ
Can the TKA30B-C be used in industrial control gear that has 18-36VAC available and needs 12V output?
Yes, its published input range is 18-36VAC and its output is listed as 12V constant voltage. The unit is rated at 25W for loads that match those specifications.
Is this model appropriate for powering 12V embedded electronics in automation systems?
It is intended for 12V constant-voltage output from an 18-36VAC source. With a published power rating of 25W, it suits embedded electronics that stay within that power envelope.
Can I use the TKA30B-C for 12V monitoring or control modules in a 24V-class AC environment?
It can fit that type of application when the source falls within 18-36VAC and the module requires 12V output. The provided specs list 25W power and a published output current of 250A.
Does the TKA30B-C fit space-constrained industrial or embedded builds?
The product is listed at 50.8 x 50.8 x 21.0 mm and 0.11 kg, so it is compact in physical size. Electrically, it is specified for 18-36VAC input and 12V constant-voltage output.
Is the TKA30B-C suitable for outdoor exposure or just wide-temperature operation?
The published operating range is -40°C to +85°C, which supports use across broad temperature conditions. However, there is no IP rating in the provided specs, so the data does not confirm outdoor or wet-location suitability.
What is the spec difference between TKA30B-C and TKA30B-B?
According to the provided sibling data, both are listed as 25W converters with 18-36VAC input, 12V output, and identical dimensions of 50.8 x 50.8 x 21.0 mm. The published distinction is output current: TKA30B-C is listed at 250A and TKA30B-B is listed at 310A.
