FAQ
Can I use the TKA30B-B in a 24V-class industrial DC system that needs +5V / ±12V output for control electronics?
Yes, the published input range is 18-36VDC, which fits 24V-class DC systems within that range. The output is listed as +5V / ±12V with a 25W power rating.
Is the TKA30B-B suitable for embedded or automation devices that require +5V / ±12V power from an 18-36VDC source?
It is designed for 18-36VDC input and +5V / ±12V output operation. The product is rated at 25W, so the connected embedded or automation load needs to stay within that published power limit.
Can this converter be used for +5V / ±12V interface or signal-conditioning hardware in industrial equipment?
It can be considered where the available source is 18-36VDC and the downstream hardware uses +5V / ±12V output. The provided specifications list 25W power and output currents of 700~3500mA for +5V and ±62~±310mA for ±12V.
Would the TKA30B-B make sense for compact +5V / ±12V power conversion inside automation assemblies?
Its listed dimensions are 50.8 x 50.8 x 21.0 mm and the weight is 0.11 kg, which supports use in compact assemblies. The electrical spec is 18-36VDC input with +5V / ±12V output at 25W.
Is the TKA30B-B rated for outdoor environments or only temperature extremes?
The published operating temperature range is -40°C to +85°C, so the unit is specified for a wide temperature span. No IP rating is provided in the specs, so outdoor or water-exposed suitability is not established by the listed data.
How does TKA30B-B differ from TKA30B-C?
The provided sibling specs show both models at 25W with 18-36VDC input and the same 50.8 x 50.8 x 21.0 mm dimensions. The published difference is output voltage and current: TKA30B-B is listed at +5V / ±12V (±62~±310mA), while TKA30B-C is listed at +5V / ±15V (±50~±250mA).
