Series SIR
Surface Mount
DC to DC Converters
Single and Dual Output

Wide Input Range up to 3.33:1 
Isolated Regulated up to 8 Watt DC-DC Converters
Fully Regulated All Units Shielded

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.

  • 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
    5-15V DC = ±1.5%
    8-24V DC = ±1.5%
    18-36V DC = ±1.0%
    36-60V DC = ±1.0%
    18-60V DC = ±1.5%
  • 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.
