Test conditions and notes8

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1μF & 47μF parallel capacitor.
3. Tolerance : includes set up tolerance, line regulation and load regulation.
4. Length of set up time is measured at first cold start. Turning ON/OFF the power supply may lead to increase of the set up time.
5. Heat sink HS1,HS2 can not be shorted.
6. Heat sink HS1 must have safety isolation distance with system case.
7. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )
8. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).

FAQ

Can I use the PSC-35A-C in a small 12V industrial standby power application?

It delivers 13.8V constant-voltage output at up to 1.7A, with 35.88W total output power. That makes it a fit for smaller 12V-class standby applications that need UPS function support and stay within those limits.

Is the PSC-35A-C suitable for compact embedded or control devices with 12V battery backup?

Yes, for lower-power systems it offers 13.8V and 1.7A from a 90-264VAC input range. It fits embedded, control, or instrumentation use cases where the required charging or backup power does not exceed 35.88W.

Can the PSC-35A-C be used where a covered version of a 13.8V charger is preferred?

This model has the same 13.8V, 1.7A, and 35.88W electrical rating as the PSC-35A, and the feature list notes that -C types are models with L-bracket and cover available. It is relevant when the application calls for that covered variant while staying in the same low-power 12V-class range.

Can the PSC-35A-C be used outdoors or in washdown areas?

The listed operating temperature range is -30°C to +70°C, but the provided specs do not show an IP rating. Without an IP rating in the spec set, outdoor or washdown use should not be assumed.

What is the difference between PSC-35A-C and the other 13.8V PSC options?

PSC-35A-C is rated at 35.88W, 13.8V, and 1.7A, while PSC-60A and PSC-60A-C are 59.34W and 2.8A, PSC-100A and PSC-100A-C are 100.05W and 4.75A, and PSC-160A and PSC-160A-C are 160W and 7.6A. Compared with PSC-35A, the PSC-35A-C keeps the same electrical rating but has enclosed dimensions of 86.4 × 59.6 × 30.0 mm and weight of 0.145 kg.
