FAQ
Can the TKA30B-C be used in industrial control gear that has 18-36VDC available and needs ±15V output?
Yes, its published input range is 18-36VDC and its output is listed as +5V / ±15V. The unit is rated at 25W for loads that match those specifications.
Is this model appropriate for powering ±15V embedded electronics in automation systems?
It is intended for +5V / ±15V output from an 18-36VDC 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 ±15V monitoring or control modules in a 24V-class DC environment?
It can fit that type of application when the source falls within 18-36VDC and the module requires ±15V output. The provided specs list 25W power and a published output current of ±50 ~ ±250mA.
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 110g, so it is compact in physical size. Electrically, it is specified for 18-36VDC input and +5V / ±15V 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 18-36VDC input and identical dimensions of 50.8 x 50.8 x 21.0 mm. The published distinction is output voltage and current: TKA30B-C is listed at +5V / ±15V (±50 ~ ±250mA) and TKA30B-B is listed at ±12V (±62 ~ ±310mA).
