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 for a small 12V alarm or security backup application?

It provides 13.8V constant-voltage output at up to 1.7A, with 35.88W total output power. That makes it suitable for smaller 12V-class standby or backup applications that align with a 13.8V charging profile and do not exceed 1.7A.

Is the PSC-35A appropriate for low-power embedded control equipment that uses a 12V battery-backed supply?

This unit is aimed at low-power 13.8V applications and can supply up to 1.7A from a 90-264VAC input. It fits embedded or control equipment where the charging and backup requirement stays within 35.88W.

Can the PSC-35A support a compact automation panel that only needs modest charging current?

For lighter-duty 12V-class automation or panel applications, the 13.8V and 1.7A rating is appropriate when the load and charging demand stay within 35.88W. Its UPS function also makes it relevant where backup continuity is needed.

Is the PSC-35A suitable for indoor use in cold or hot equipment areas?

The operating temperature range is -30°C to +70°C, which gives it a broad temperature window for indoor equipment spaces. The provided specs do not include an IP rating, so outdoor suitability is not established here.

How does the PSC-35A compare with the other 13.8V PSC models?

The PSC-35A is the 13.8V model in the PSC-35 series, rated at 35.88W with a main output of 1.7A and a charger output of 0.9A. The PSC-35B is the 27.6V variant in this series, rated at 35.88W with a main output of 0.85A and a charger output of 0.45A. Both are available in PCB or enclosed types.
