This series of high efficiency, wide input range, encapsulated regulators come in 90 different models. These units feature a 500 VOLT DC input to output isolation in both single and dual output models. The LR 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.

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: 40 KHz, typ.

Options Available

• Per Mil. Std. 883
• Expanded operating temp. (-55º C to +85º C)
• 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

• Encapsulated semiconductors, conservatively rated for maximum reliability.
• Load regulation (see table for typical variation at different loads)
• Line regulation = Typical values

1. 5-15V DC = ±1.5%
2. 8-24V DC = ±1.5%
3. 18-36V DC = ±1.0%
4. 36-60V DC = ±1.0%
5. 18-60V DC = ±1.5%

• High efficiency - up to 80%
• 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%
• Single and dual isolated outputs
• 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.
