FAQ

Can I use the TKA30C-B in a low-power industrial control panel that needs 12V output?

This model is a constant-voltage DC-DC converter with a 12V output and 25W power rating. It fits low-power industrial control or automation sections that stay within that 25W budget and use a 36-72VAC input range.

Is the TKA30C-B suitable for embedded electronics in equipment with a wide AC input range?

It is designed for 36-72VAC input, so it matches equipment that operates across that stated range. Its 12V constant-voltage output and 25W rating make it more appropriate for embedded control electronics than for higher-load 12V devices.

Can the TKA30C-B be used for automation subsystems where space is limited?

The unit measures 50.8 x 50.8 x 21.0 mm and weighs 0.11 kg, so it is relatively compact for enclosed automation hardware. It is still a 25W, 12V constant-voltage converter, so the load must fit within those limits.

What is the difference between the TKA30C-B and TKA30C-C?

Both models are 25W constant-voltage converters with 12V output, 36-72VAC input, 50.8 x 50.8 x 21.0 mm dimensions, 0.11 kg weight, -40 C to +85 C operating temperature, CE and c_emc certifications, and a 2-year warranty. The listed difference is output current: TKA30C-B is 310A and TKA30C-C is 250A.

Is the TKA30C-B suitable for outdoor or harsh-temperature use?

The specified operating range is -40 C to +85 C, which supports use across a wide temperature span. No IP rating is listed in the provided specs, so outdoor exposure or washdown suitability is not established from this product data.
