310-Watt AC-DC meets Medical Standards

With 2 MOPP isolation, class I and II protection and high efficiency of at least 87.5 percent, the 310-Watt UI31024SP ac-dc power supply from Polytron Devices is suitable for medical applications and meets CEC level VI, UL, CUL, CE, ES60601-1, EN60601-1 and IEC60601-1 3rd Edition safety standards. This model also has a desktop package of 7.87" x 3.94" x 1.65", as well as short circuit, over-temperature and over-current protection.

The UI31024SP has a universal input range of 90- to 264-Vac, 50 or 60 Hz. Maximum input current is 5A at 115Vac input voltage and 2.5A at 230Vac input. Start-up inrush current is less than 150A at 230Vac. Turn on time is under 35ms and rise time is under 50ms. Hold-up time at 110Vac input and full load is at least 5 ms.

The standard output voltage is 24Vdc and the rated current is 12.5A. Line regulation is 2%, load regulation is 5% and output tolerance is 5%. Output ripple and noise is a maximum of 480 mV peak-to-peak. The overvoltage protection trip point is under 32V. Short-circuit protection shuts down the unit and ac power must be cycled to reset the power supply. The no-load power consumption is under 0.5W.
