This series of encapsulated converters come in 60 different models. The highly regulated output is isolated from the input. The units will operate over the temperature range of -25º C to +70º C. No heat sink is required. These units are excellent for applications where the input voltage varies ±10% and the output must be held to ±0.1% single/and ±0.2% dual. The output voltage is maintained to within 0.2% from no load to full load for single and 0.4% for dual. OPTIONS AVAILABLE Per Mil. Std. 883 Expanded operating temp (-55º C to +85ºC) Stabilization Bake (125º C ambient) Temperature Cycle (-55º C to +125º C) Hi Temp, full power burn in (100% power, 125º C case temp) FEATURES Excellent voltage regulations ±0.1% single / ±0.2% dual Encapsulated semiconductors, conservatively rated for maximum reliability Excellent load regulations 0.2% single / 0.4% dual Up to 1.0 watts output power at 70º C ambient Low output ripple 100 megohm 500V DC isolation Single and dual isolated outputs Low profile, ultra-miniature size No output capacitor required No heat sink required TYPICAL CHARACTERISTICS: Test conditions: 25º C ambient. Output voltage tolerance:±1% single / ±2% dual Line regulations: ±0.1% single/±0.2% dual (for the input voltage range of ±10%) Load regulation: 0.2% single/0.4% dual Converter frequency: 20-40 KHz Operating temperature: -25º C to +70º C ambient. Output voltage temperature coefficient: 0.01%/ºC Storage temperature: -55º C to +125º C Isolation: 100 megohms minimum at 500 volts DC Short circuit protection: Temporary
