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.

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-200-3.3 for 3.3V industrial logic or control electronics?

Yes, this is a 3.3V constant-voltage supply rated for 132W and 40A with 25CFM forced air cooling (28A under free air convection). It fits high-current 3.3V industrial logic, controller boards, and embedded electronics that need a regulated 3.3V rail within that output limit.

Is the MPS-200-3.3 suitable for FPGA, SBC, or embedded compute platforms that run on 3.3V?

It can be used where the equipment is designed for a 3.3V constant-voltage input and the total draw stays within 132W and 40A. The full 40A rating requires 25CFM forced air cooling, with 28A available under free air convection.

Can this power supply support multiple 3.3V boards in a production test fixture?

Yes, if the combined 3.3V load remains within 132W and 40A. That output profile is well aligned with factory test fixtures, embedded validation racks, and grouped low-voltage electronics that share a common 3.3V bus.

Would the MPS-200-3.3 work for telecom or networking control boards that need 3.3V DC?

It is a strong candidate for 3.3V telecom, networking, and processor-adjacent control boards that require a constant-voltage source. The 90-264VAC input also makes it easier to use in installations with different AC input standards.

Can the MPS-200-3.3 be used in outdoor cabinets or only indoors?

The operating temperature range is -20°C to +70°C (subject to the derating curves), which supports a broad indoor equipment environment. Since no IP rating is listed, it should be used in a protected enclosure rather than an exposed outdoor location.
