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.

  • 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.

Larger Size Drawing

Use 50 K Ohm trim rated 1/4 Watt between trim pin and negative input.  Trim down to raise output voltage to a maximum of 5%.  Do not go beyond the 5%.  Reducing the resistance value further could damage the module.
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.
