PSMBU250
The PSMBU250 series of class I medical AC/DC switching power supplies provides 250 Watts of continuous output power in a 5.00” x 3.00” x 1.46” open frame package. This series consists of single output models with a wide input voltage range of 90~264VAC. Some features include high efficiency up to 94%, 2MOPP insulation, and short circuit, over current and over load protection. All models meet FCC Part-18, CISPR-11, and EN55011 Class B emission limits. This series also has IEC60601-1 Edition 3.1, ES60601-1:2005(R2012), CSAC22.2 NO. 60601-1:14, and EN60601-1:2006/A1:2013 safety approvals. All models are RoHS2 compliant and have been 100% burn-in tested.

| Notes & safety | |
| Notes: | 1. Output can provide up to peak load when power supply starts up. Staying in more than rated load continually is not allowed. 2. At factory in 60% rated load condition, each output is checked to be within voltage accuracy. 3. Line regulation is defined by changing ±10% of input voltage from nominal line at rated load. 4. Load regulation is defined by changing ±40% of measured output load from 60% rated load. 5. Ripple is measured from peak to peak with a bandwidth-limit of 20MHz (measured at the output connector with a 0.1uF ceramic capacitor and a 47uF electrolytic capacitor) . 6. Hold up time is measured from the end of the last charging pulse to the time which the main output drops down to low limit of main output at rated load and nominal line. 7. Efficiency is measured at rated load and nominal line Due to advances in technology, specifications subject to change without notice. |
