Photonic Sourcing

Highly Regulated
Hi Reliability
Isolated
Ultraminiature DC-DC Converters

Low Profile .5" x 1" x .3" ht. up to 1 Watt
No Heat Sink or Electrical Derating Required

This series of encapsulated converters come in 60 different models. The highly regulated output is isolated from the input. The units will operate over the temperature range of -25º C to +70º C. No heat sink is required. These units are excellent for applications where the input voltage varies ±10% and the output must be held to ±0.1% single/and ±0.2% dual. The output voltage is maintained to within 0.2% from no load to full load for single and 0.4% for dual.

Options Available

• Per Mil. Std. 883
• Expanded operating temp (-55º C to +85ºC)
• Stabilization Bake (125º C ambient)
