The Cosel PMA100F-3R3-J1 is a high-performance AC-DC power supply designed for medical equipment applications. It features a universal input voltage range of AC85-264V, making it suitable for global use. The converter provides a stable 3.3V DC output with a maximum current of 20A.
Key electrical specifications include an efficiency of up to 67% at 200V input, a line regulation of 20mV maximum, and a load regulation of 40mV maximum. The operating temperature range is -10°C to 70°C, with a hold-up time of 20ms at 100V input. Overcurrent protection is active at 105% of the rated output.
Designed for easy integration, this power supply features a chassis mount type and measures 167.9mm in length, 34.0mm in width, and 93.0mm in height. It holds safety agency approvals including CE, cURus, and TUV, and complies with RoHS3 standards.
The PMA100F-3R3-J1 accepts an input voltage of 85-264 VAC and provides a fixed 3.3 V DC output.
This AC/DC converter uses a chassis mount packaging style for secure installation.
The device operates reliably within a temperature range of -10°C to 70°C.
The converter provides 2 kV of isolation voltage between input and output circuits.
Typical efficiency ranges from 66% at 100VAC input to 67% at 200VAC input.
Overcurrent protection activates above 105% of the rated current and automatically recovers.
