FAQ

Can I use the SKA20B-15 to run a 15V industrial control or embedded subsystem?

Yes, it is a constant-voltage converter with a 15V output and an 18-36VDC input range. It can support 15V loads up to 1.33A, with a maximum output power of 20W.

Is the SKA20B-15 suitable for 15V automation electronics inside machinery or cabinets?

It can be suitable for 15V automation electronics if the available input falls within 18-36VDC. The connected load must remain within the converter's 1.33A output current and 20W output rating.

Can this converter power 15V industrial sensors or signal-processing modules?

This model is intended for fixed 15V output applications and uses constant-voltage operation. It fits 15V devices that require no more than 1.33A from a source in the 18-36VDC input range.

How does the SKA20B-15 handle temperature and environmental exposure?

The specified operating temperature range is -40°C to +85°C, which covers a wide set of temperature conditions. No IP rating appears in the provided specs, so the product page does not classify it for outdoor or washdown exposure.

How is SKA20B-15 different from SKA20B-05 and SKA20B-12?

The three SKA20B versions have the same 20W power rating, 18-36VAC input range, compact 50.8 × 25.4 × 11.2 mm size, 0.0312 kg weight, and -40°C to +85°C operating temperature. The output options are 5V at 4A for SKA20B-05, 12V at 1.66A for SKA20B-12, and 15V at 1.33A for SKA20B-15.
