See derating chart. Storage Temperature: –55°C to +85°C Vibration: Per MIL-STD-810B, Method 514, Procedure I, Curve AB (to 50 Hz) Shock: Per MIL-STD-810B, Method 516, Procedure V Safety Standards: • UL 1950, Third Edition • CSA C22.2 No. 950 • CE marked • CB Scheme Finish: Clear aluminum chassis. Also serves as heat sink. Mounting: Units can be mounted on several surfaces. Mounting holes will accept “press fit” #6-32 threaded fasteners. For efficient cooling, allow unrestricted air flow. Forced air cooling may be recommended. DERATING CHART 100% M CF IR 100 LA RA TU NA AC Input: Field selectable taps for 100/117/220/230-240 VAC ±10%; 47-63Hz. See chassis ID lable for jumper and line fusing requirements. For 50Hz operation derate output by 10%. DC Output: See selection guide for voltage/current ratings. The output is floating; either positive or negative terminal can be grounded. Output adjustment range is ±10%, except variable 10-18V outputs. Line Regulation: ±0.05% for 10% line change Load Regulation: ± 0.05% for 50% load change Thermal Regulation: ±0.02% per °C maximum, ±0.005% per °C typical Output Ripple: 2 mV RMS maximum, 3 mV P-P Dynamic Response: 30 microseconds for 50% load change Stability: ±0.3% for 24 hour period after 1 hour warm-up Short Circuit and Overload Protection: Foldback current limiting, set at 120% of nominal Overvoltage Protection: Crowbar overvoltage protection is standard on all 5VDC main outputs and is factory set at 6.2V±0.4V (fixed). Optional universal OVP module adjustable from 4.5 to 36V is available for other models. Remote Sensing: Standard on all outputs above 30 watts. Remote sense will compensate for a cable drop of 0.25V. Protected against open or shorted sense leads. Twisted pair sense leads are recommended. Efficiency: 5V units: 45%; 12 and 15V units: 55%; 24V and higher units: 60%. High Reliability Capacitors OVP Module PERCENT OF RATED OUTPUT The BVA series is the premium grade, open frame line of linear DC power supplies. Designed to operate over a wide range of AC power sources found worldwide, the BVA series is especially suited for OEM applications where cost is a significant factor. The field selectable universal input (100/117/220/230-240VAC) reduces your inventory cost by allowing to use just one standard model regardless of destination. 80% 60% 40% Natural air 100% 70% 40% convection Forced air (100 CFM) 100% 100% 70% 10 20 30 40 50 60 AMBIENT TEMPERATURE Phone (630) 628-9999 • Fax (630)628-9922 • http://www.powervolt.com 70
