Test conditions and notes5

1.All parameters are specified at normal input(24Vdc), rated load, 25℃ 70% RH ambient.
2.Ripple & noise are measured at 20MHz by using a 12" twisted pair terminated with a 0.1μf & 47μf capacitor.
3.Line regulation is measured from low line to high line at rated load.
4.Load regulation is measured from 0% to 100% rated load.
5.The final equipment must be re-confirm that it still meet EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.”(as available on http://www.meanwell.com)

FAQ

What applications is the Mean Well SCW08W8-15 designed for?

The SCW08W8-15 is an 8W DC-DC converter module intended for equipment that needs a regulated 15V DC output from a very wide DC input range. Its 9-75V DC input range makes it relevant for industrial, embedded, and mobile power environments where input voltage can vary significantly.

What input voltage range does the SCW08W8-15 support?

This model supports an ultra-wide 9-75V DC input range. Mean Well also identifies that range as covering nominal 12V, 24V, 36V, 48V, and 72V DC systems.

What output does the SCW08W8-15 provide?

The SCW08W8-15 provides a 15V DC output and is rated for 8W of output power. That makes it a fit for applications specifically requiring a 15V rail from a high-variation DC source.

How does the SCW08W8-15 compare with narrower-input DC-DC converters?

A key differentiator of the SCW08W8-15 is its 8:1 input range of 9-75V DC, which is much broader than many standard-input converter modules. For buyers working across multiple nominal DC systems, that wider range can reduce the need to source different converter variants.

Is the SCW08W8-15 suitable for harsh temperature environments?

Yes, this model is specified for operation from -40°C to +90°C. That wide operating range makes it more suitable for demanding environments than converters limited to standard indoor temperature conditions.

What protection and isolation features are included in the SCW08W8-15?

The SCW08W8-15 includes short circuit protection with continuous mode, overload protection, over-voltage protection, and UVLO. It also provides 3KV DC input-to-output isolation, which is an important specification for applications that require electrical separation between input and output sides.
