This series of high efficiency, wide input range, encapsulated regulators come in 85 different models. These units feature a 500 VOLT DC input to output isolation in both single and dual output models. The SIR Series will operate over a temperature range of -25º C TO +70º C with no heat sink or electrical derating. These units are excellent for applications where input voltage varies dramatically, yet a high efficiency and output voltage regulation must be maintained. FEATURES Voltage regulation over input range of Encapsulated semiconductors, conservatively rated for maximum reliability. Load regulation (see table for typical variation at different loads) Line regulation = Typical values High efficiency - up to 82% Will operate over a temperature range of -25º C to +70º C with no heat sink or electrical derating. Isolation - 100 megohms at 500 volts DC External output trimming pin standard +5% Each unit is supplied with an external control pin. This "C" pin, when connected to the negative (-) input, will disable the unit, allowing for remote shutdown. TYPICAL CHARACTERISTICS: Test conditions: 25º C ambient Operating temperature: -25º C to +70º C ambient Output voltage tolerance: ± 1% at typical input voltage Output voltage temperature coefficient: 0.02%/ºC Storage temperature: -55º C to 125º C Short circuit protection: Temporary Operating frequency: 40Khtz, typical OPTIONS AVAILABLE Expanded operating temp. (-55º C to +85º C) Stabilization Bake (125º C ambient) Temperature Cycle (-55º C to +125º C) High Temp, full power burn in (100% power, 125º C case temp)
