AC-DC Power Supplies PBR500 Series 500 Watts 450-500W Forced Cooled 350-400W Convection Cooled ITE & Medical (BF) Safety Approvals U-Channel 4 x 7 Package 5V Standby & 12V Fan Supply AC OK, Inhibit & Remote Sense Class B Conducted & Radiated Emissions 3 Year Warranty The PBR500 series of AC-DC switching power supplies, in a package of just 4 x 7 x 1.7 inches, deliver Dimensions: 450-500 watts of continuous power with forced air cooling or 350-400 watts with convection cooling. PBR500: The units are constructed on a U-Channel for mechanical support and heat sinking. A cover and fan 7.0 x 4.00 x 1.70 (177.8 x 101.6 x 44.5 mm) assembly can be added during manufacturing. They are designed for both ITE/Industrial and medical applications including those needing BF rated insulation with an operation altitude up to 5000 meters.

For covered version, replace B in the part number with C, e.g PBR500PS12C. V3 not available on covered version. 2. 350-400 W without moving air or 450-500 W with 30 CFM forced air provided by the user. 450-500 W for -C version 3. Ripple and noise is the maximum peak-to-peak voltage value measured at the output with 20 MHz bandwidth, at rated line voltage and output load, and with a 10 F tantalum capacitor in parallel with a 0.1 F ceramic capacitor. 4. All models may be operated at no-load without damage. At no load, output voltage fluctuates beyond 5% due to burst-mode operation of the control IC for energy saving.
