Test conditions and notes9
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
  2. 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. 3. Tolerance : includes set up tolerance, line regulation and load regulation.
  4. 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. 5. Heat sink HS2,HS3 can not be shorted.
  6. 6. Heat sink HS2,HS3 must have safety isolation distance from system case.
  7. 7. The power supply is considered a component which will be installed into a final equipment. All the EMC tests are been executed by mounting the unit on a 230mm*230mm metal plate with 1mm of thickness. 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. 8. Please refer to suggest application (2)、(4) in page 3.
  9. 9. 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-100B for a 27.6V battery-backed industrial control panel?

Yes, this model provides a 27.6V DC output and includes a UPS function, which fits battery-backed control equipment designed around a 27.6V DC rail. Its 2.4A rated CH1 current and 100.74W total rated power suit lower-power control, alarm, or automation loads that stay within those limits.

Is the PSC-100B suitable for embedded or automation equipment that needs AC input flexibility?

It can fit embedded or automation systems that need a wide AC input range, because it accepts 90-264VAC. On the DC side, the load still needs to match the unit's 27.6V output and stay within its 2.4A rated CH1 current (100.74W total rated power).

Can the PSC-100B be used for standby security or monitoring equipment with battery backup?

It is appropriate for standby equipment that operates on a 27.6V battery-backed supply, especially where the UPS function is part of the design. The output is 27.6V with 2.4A rated on CH1, so it fits lighter-duty monitoring, alarm, or communications loads within the 100.74W total rating.

Would the PSC-100B work for a small 27.6V telecom or network support power system?

It can work for compact telecom or network support equipment if the system is designed for a 27.6V DC source and the load stays within the 2.4A rated CH1 current and 100.74W total rated power. Its relay contact AC OK and battery low signals can also be used for status monitoring.

What is the difference between the PSC-100B and other PSC series charging models?

On the PSC-100 datasheet, the 27.6V models are PSC-100B (PCB only) and PSC-100B-C (enclosed, with L-bracket and cover) at 100.74W, rated 2.4A on CH1 and 1.25A on CH2, 88% efficiency. The 13.8V models are PSC-100A and PSC-100A-C at 100.05W, rated 4.75A on CH1 and 2.5A on CH2, 86% efficiency. Other PSC series models are not covered by this sheet.

Is the PSC-100B meant for outdoor use or harsh ambient temperatures?

The operating temperature range is -20°C to +70°C, with load derating at higher temperatures per the derating curve. No IP rating is listed, and the PSC-100B is a PCB-only (open frame) component intended to be installed inside end equipment, so it is not suited to outdoor use.
