220V to 5V AC-DC Isolated Switching Power Supply Module

  • RM15.00

  • Product Code: PS-B-5V 2A
  • Availability: In Stock

Product features:

Input Voltage Range: AC50V-277V DC70V-390V

No-load Power: < 0.05W  Full Load Power: < 4W

Output Characteristics: Multiple modules with the same voltage can be connected in parallel to meet the demand for high current in a small space.

Output Voltage

  • The output voltage is 5V ±0.15V at both no-load and full-load conditions.
  • The voltage decreases by 0.1V under light load and recovers under heavy load.
  • At 50% load, the ripple is 60mV.


Output Current

  • The output current range is 5V 0mA-700mA, and it operates in constant current mode at full load.


Test Resistance

  • A 7-ohm test resistance is used to test the 5V voltage (actual voltage is 4.9V).

Output Indicator: Green light.

Output Power: 3.5W with an efficiency of approximately 80%.

Output Protection: Overvoltage, overcurrent, overtemperature, over power, and short circuit protection.

Operating Temperature: -20°C to 70°C. High-grade models with green gold capacitors can withstand temperatures up to 105°C for 10,000 hours. Lifespan is greater than 5 years at 70°C and approximately 20-50 years at room temperature (not recommended for use above 70°C). Output filtering is done with high-quality solid-state capacitors.
