Description
RPS-500 is a 500W highly reliable green PCB type medical power supply with a high power density on the 5” by 3” footprint. It accepts 80~264VAC input and offers various output voltages between 12V and 48V.The working efficiency is up to 94% and the extremely low no load power consumption is down below 0.5W.RPS-500 (blank type only) is able to be used for both Class I (with FG) and Class II(no FG) system design. The extremely low leakage current is less than 220KA. In addition, it conforms to international medical regulations (2*MOPP) and EMC BS EN/EN55011, perfectlyfitting all kinds of BF rated “patient contact” medical system equipment. RPS-500 series also offers the enclosed style models( -C/ TF /SF )

| NOTE | 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25 of ambient temperature. 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12″ twisted pair-wire terminated with a 0.1of & 474 parallel capacitor. 3. Tolerance : includes set up tolerance, line regulation and load regulation. 4. Derating may be needed under low input voltages. Please check the derating curve for more details. 5. Touch current was measured from primary input to DC output. 6. The ambient temperature derating of 3.5″C/1000m with fanless models and of 5″C/1000m with fan models for operating attitude higher than 2000m(6500ft). 7. Please refer to ‘Derating curve”. 8. The power apply is considered a component which will be installed into a final equipment. All EMC tests are executed by mounting the unit on a 360mm”360mm metal plate with 1mm of thickness. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on http://www.meanwell.com). ※ Product Liability Disclaimer : For detailed information, please refer to https://www.meanwell.conVserviceDisclaimerzspx | |||||
