Series JR
DC to DC Converters
Single and Dual Output

Wide Input Range up to 3.33:1
Isolated, Regulated up to 15 Watt DC to DC Converters
Full Regulated All Units Shielded

This series of high efficiency, wide input range, encapsulated regulators come in 51 different models. These units feature a 500 VOLT DC input to output isolation in both single and dual output models. The JR 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 Single and dual isolated outputs Voltage regulation over input range of Unit Low High JRA 18V 36V JRB 36V 60V JRC 18V 60V Encapsulated semiconductors, conservatively rated for maximum reliability. Load regulation (see table for typical variation at different loads) Line regulation = Typical values 18-36V DC = ±1.0% 36-60V DC = ±1.0% 18-60V DC = ±2.0% High efficiency - up to 84% Will operate over a temperature range of -25º C to +70º C with no heat sink or electrical derating 6 sided shielding 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: ± 2% at typical input voltage Output voltage temperature coefficient: 0.02% / º C Storage temperature: -55º C to 125º C Short circuit protection: Temporary Operating frequency: 40Khtz, typical OPTIONS AVAILABLE Per Mil. Std. 883 Expanded operating temp. -55º C to +85º C Ambient Stabilization Bake (125º C ambient) Temperature Cycle -55º C to +125º C High Temp, full power burn in (100% power, 125º C case temp)
