Fully protected against short circuit and output overload. The hiccup type protection will be activated at 120~160% rated load and recovers automatically after fault condition is removed.
OVER VOLTAGE PROTECTION
Provided on output channel 1 only at 115%~135% rated output voltage. Output will be shut down when this protection is activated.

When the temperature of TSW1 which detect on heat sink of power transistor reaches 95℃, This protection is activated. Then output will be shut down and recovers automatically after temperature goes down.
POWER GOOD / FAIL SIGNAL
TTL logic high for power good and TTL low for power fail. When the output voltage reaches 90% of rated value, a +5V TTL signal will be sent out with a 10~500ms delay; At least 1ms before the output voltage goes below 90% of the rated value, the TTL signal will be turned off. * MPS-200-3.3 does not have this function.

Test conditions and notes6
  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. 33% Duty cycle maximum within every 30 seconds. Average output power should not exceed the rated power.
  5. 5. 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 http://www.meanwell.com)
  6. 6. Derating may be needed under low input voltages. Please check the derating curve for more details.

FAQ

Can I use the MPS-200-48 for 48V industrial automation or control systems?

Yes, this model provides 48V constant-voltage output rated at 200W and 4.2A with 25CFM forced air cooling (3A under free air convection). It is suitable for 48V automation, control, and industrial electronics that are designed for a 48V DC supply within that output range.

Is the MPS-200-48 appropriate for 48V networking or telecom equipment?

It can be a fit for 48V telecom, networking, and communications hardware that expects a constant 48V DC input. The full 4.2A rating requires 25CFM forced air cooling; under free air convection the output is limited to 3A.

Would this 48V power supply work for embedded or industrial PoE-adjacent systems that run on 48V DC?

It is suitable for embedded and industrial systems that take a 48V constant-voltage input and stay within 200W and 4.2A. Buyers typically choose this type of output where 48V distribution is preferred over lower-voltage, higher-current rails.

Can the MPS-200-48 power a 48V bench setup or validation rig?

Yes, it can serve as a 48V source for development benches, validation rigs, and industrial test equipment that need a constant-voltage supply. Its 90-264VAC input is useful when the bench may be operated from different AC mains sources.

Is the MPS-200-48 rated for outdoor exposure?

The published specs include an operating temperature range of -20°C to +70°C (subject to the derating curves), but no IP rating is listed. That points to indoor or enclosure-protected use instead of direct outdoor exposure.
