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. 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 360mm*360mm 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 )
- 5. Derating may be needed under low input voltage. Please check the derating curve for more details.
- 6. Peak current should reduce to 150% of rated value if the input voltage <110VAC.
- 7. Heat Sink HS1,HS2,HS3 can not be shorted.
- 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 PID-250B for a 24V PLC, HMI, and I/O control cabinet?
Yes, this model is aligned to 24V constant-voltage automation loads. It provides 250W at 24V with 9.4A output current and accepts 90-264VAC input, which fits many control-panel applications built around a 24V DC bus.
Is the PID-250B suitable for industrial systems that have short startup surges?
It can be a good fit where the load briefly rises above the steady-state level. The features list a peak load of 170% for CH1 within 10 sec, which is useful for automation or embedded equipment with temporary inrush or startup demand.
Can the PID-250B be used in equipment that needs a remotely controlled main output?
Yes, the features include remote control for CH1. That makes it relevant for machine or embedded systems where the 24V output needs to be managed by higher-level control logic rather than always running continuously.
Is the PID-250B appropriate for applications that may need controlled current behavior across different voltage levels?
No, the PID-250B is a constant-voltage power supply with fixed outputs of 24V (CH1) and 5V (CH2). It does not support a constant-current mode or a variable voltage range across different levels; the voltage adjustment range is limited to ±10% of the nominal output.
Can the PID-250B be used outdoors or in exposed environments?
The provided specs do not list an IP rating, and this is described as an open frame power supply, so exposed outdoor use is not supported by the supplied data. Its operating temperature range is -20°C to +70°C, so it is better suited to protected equipment or an enclosure that keeps conditions within that range.
