Series KR

DC to DC Converters

Single and Dual Output

Wide Input Range up to 3.33:1

Isolated Regulated up to 20 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 KR 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
• Encapsulated semiconductors, conservatively rated for maximum reliability.
• Load regulation (see table for typical variation at different loads)
• Line regulation = Typical values
• 18-36V DC = ±1.5%
• 36-60V DC = ±1.5%
• 18-60V DC = ±3.0%
