Linear Regulated DC Power Supply 240/480V Input Voltage Series: BVA SPECIFICATIONS: AC INPUT: 240/480 VAC +/–10%; 47-63Hz. See chassis ID label for jumper and line fusing requirements. 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: 2mV rms maximum, 3mV P-P. This latest addition to our Power Supply Line has been introduced after much demand. Endless applications will be more cost effective with DC power attainable directly from your high line. All power supplies listed here have an input voltage of 240/480 VAC. BENEFICIAL FEATURES INCLUDE: • 240/480 VAC input; 50/60 Hz • Output is regulated DC power • Up to 720 watts regulated output • Eliminates step - down control transformers • 5, 12, 15, 24, 28, & 48 VDC outputs available • MTBF over 250,000 hours • Low radio interference • Output ripple as low as 2mV RMS • Standard overload protection • Standard reverse polarity protection • Standard short circuit protection • Standard remote and local sense (most models) • Designed to meet UL 1950 / CSA 950 / and EMC directives • Vibration and shock per MIL-STD-810B • Two year warranty • Screw terminal block • Overvoltage protection (standard on 5 volt models) • Input fuse 12 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 5 VDC 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%. OPERATING TEMPERATURE: 0°C to 50°C full rated load, derate linearly to 40% at 70°C. STORAGE TEMPERATURE: –55°C to +85°C. VIBRATION: Per MIL-STD-810B, method 514, procedure 1, curve AB (to 50Hz). SHOCK: Per MIL-STD-810B, method 516, procedure V. SAFETY STANDARDS: Designed to meet safety regulations of UL, CSA, VDE, CE, and other international standards. VALUE ADDED OPTIONS INCLUDE: • Mounting spacers DYNAMIC RESPONSE: 30 microseconds for 50% load change. FINISH: Clear aluminum chassis. Chassis also serve 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. Phone (630) 628-9999 • Fax (630)628-9922 • http://www.powervolt.com
