Product Overview
US Plug 12V 3A Medical Power Adapter | Low Leakage Current & 2×MOPP for Vital Signs Monitors
This 12V 3A (36W) medical-grade AC/DC power adapter is purpose-built for portable and bedside vital signs monitors—including devices that measure ECG, SpO2, blood pressure, respiration rate, and temperature—in U.S. clinical, home healthcare, and emergency settings. Certified to UL 60601-1 (4th Edition) and designed with 2×MOPP (Means of Patient Protection) isolation, it delivers ultra-low patient leakage current (<10 µA) to ensure electrical safety during direct or indirect patient contact. Featuring a fixed NEMA 5-15P grounded US plug, this adapter meets all FDA-recognized safety standards and FCC EMC requirements, making it ideal for integration into FDA-cleared monitoring systems requiring reliable, clean, and compliant power.
Key Features & Benefits
UL 60601-1 4th Edition certified - aligns with FDA guidance for medical electrical equipment safety.
2×MOPP isolation - provides reinforced insulation (4 kVAC dielectric strength) suitable for BF-type applied parts.
Ultra-low leakage current - <10 µA (Normal Condition), critical for preventing microshock in sensitive monitoring.
Clean, regulated output - 12V ±2%, ripple <80mVp-p eliminates signal noise distorting ECG waveforms.
FCC Class B EMC compliant - avoids interference with wireless telemetry, Wi-Fi, or Bluetooth.
High reliability - MTBF >100,000 hours; validated for continuous 24/7 operation.
Frequently Asked Questions
Q: What medical safety standards does this adapter comply with?
A: It is fully certified to UL 60601-1 4th Edition and IEC/EN 60601-1, which are the global standards for medical electrical equipment safety.
Q: What is the significance of 2×MOPP protection?
A: 2×MOPP (Means of Patient Protection) provides reinforced insulation between the mains power and the patient, making it safe for use with devices involving direct patient contact (Type BF).
Q: How low is the leakage current for this medical power supply?
A: The patient leakage current is ultra-low at less than 10 µA under normal conditions and less than 50 µA under single fault conditions.
Q: Does the adapter cause interference with other medical equipment?
A: No, it is FCC Class B EMC compliant, meaning it is designed to avoid interference with wireless telemetry, Wi-Fi, or Bluetooth devices in clinical environments.
Q: Can this power adapter be used outside of the United States?
A: While it features a fixed US NEMA 5-15P plug, it supports a universal input range of 100-240V AC, 50/60Hz, making it compatible with various global grids with an appropriate socket adapter.
Q: Is it suitable for continuous 24/7 operation?
A: Yes, it is validated for continuous operation with an MTBF of over 100,000 hours, making it ideal for hospital bedside monitors.
