The NMX-754-1212BG is a 750W AC/DC converter manufactured by SL Power Electronics. It operates across a wide AC input voltage range of 90 to 264 Vac at 47 to 63 Hz. The unit includes internal fusing rated for 15 A and utilizes a thermistor to limit cold start inrush current to less than 65 A at 115 Vac and 130 A at 230 Vac.
This multi-output power supply provides user-adjustable voltage tolerances of ±5% for primary rails, with secondary tracking outputs maintaining ±4% accuracy. Line and load regulation remains within ±1% across the full AC input range and 0 to 100% load variation. Ripple and noise are controlled below 1% peak-to-peak or 100 mV.
Designed for reliability, the converter achieves 75% typical efficiency and maintains a power factor of 0.99 at full load, complying with EN61000-3-2 Class A standards. It holds regulation down to 85 Vac during brownout conditions and guarantees a minimum holdup time of 20 ms at full load after power removal. An integrated AC power fail signal asserts a TTL low state 5 ms before output voltage exits its regulation band.
The unit accepts an AC input voltage range of 90 to 264 Vac at 47 to 63 Hz.
A built-in thermistor limits cold start inrush current to less than 65 A at 115 Vac and 130 A at 230 Vac.
