Frequently Asked Questions - MPM-05-12 Mean Well
What is the MPM-05-12 power supply used for?
The MPM-05-12 is a compact AC-DC power supply that converts mains voltage to a stable 12V DC output. It is commonly used in industrial controls, instrumentation, and telecommunications equipment.
What is the input voltage range of the MPM-05-12?
It accepts a wide input voltage range of 85-264 VAC (or 120-370 VDC), making it suitable for use in most global regions without voltage selector switches.
What is the maximum output current and power?
The output is 12V DC with a maximum current of 0.42A, resulting in a total output power of 5 watts.
Does the MPM-05-12 have built-in protection features?
Yes, it includes short circuit, overcurrent, and overvoltage protection to safeguard the power supply and connected devices.
What are the typical operating temperature limits?
The operating temperature range is -30°C to +70°C, though output derating may be required above 50°C to ensure reliability and safety.
How should I connect the input and output wires?
Connect the AC input wires to the appropriate terminals (marked L, N, and ground), and the DC output to the + and - terminals. Ensure the power supply is disconnected from mains before making connections.
Is the MPM-05-12 suitable for outdoor use?
This model is designed for indoor use and is not fully sealed against moisture or dust. For outdoor or harsh environments, additional enclosure or conformal coating is required.
Can I use the MPM-05-12 to charge a battery?
It is a power supply, not a battery charger. It provides a constant voltage output, so it is not recommended for charging batteries unless a proper charge controller is used.
What is the isolation voltage between input and output?
The isolation voltage is rated at 4 kVAC, ensuring safe separation between high-voltage input and low-voltage output circuits.
What certifications does the MPM-05-12 have?
It complies with major international standards, including UL, CUL, TUV, CE, and EN norms, verifying safety and electromagnetic compatibility.
