The SL Power Electronics MBAA40W-A is a linear AC/DC converter designed for various applications, including medical use. It offers a total power output of 39W, with specific voltage outputs including 5V and +/-12V.
Key specifications include a wide AC input range (100-240 Vac) and a frequency range of 47-63 Hz. The unit provides line regulation of ±0.05% and load regulation of ±0.05%. Output ripple is a maximum of 3 mV + 0.05% of the output voltage, peak to peak. Transient response is less than 50 microseconds for a 50% load change.
This converter features automatic current limit/foldback for short circuit protection. Overvoltage protection is built-in for 5V models. Remote sensing is provided on all models, with built-in open sense lead protection (except HA series). The operating temperature range is 0°C to 50°C at full rated output, derating linearly to 40% at 70°C.
The MBAA40W-A is designed for chassis mounting and includes features such as adjustable output and remote sense. It meets various safety standards including CE, cURus, and TUV, and is approved for medical applications to UL2601-1, IEC60601-1, and CSA601.1.
The AC input voltage options are 100, 120, 215, and 240 Vac with specified tolerances: +10%, -13% for 100/120/240 Vac; +12%, -11% for 215 Vac.
The converter provides triple outputs: 5V DC and +/-12V DC.
Full rated operation is 0°C to 50°C, with linear derating to 40% output at 70°C.
The MBAA40W-A is chassis mount.
Yes, overvoltage protection is built-in on all 5V models, set at 6.2V ±0.4V.
It meets commercial standards UL1950, CSA C22.2 No. 950, EN60950 and medical standards UL2601-1, IEC60601-1, CSA601.1.
Efficiency is 45% for 5V units, 55% for 12V and 15V units, and 60% for 20V and 24V units.
