Standard features include an ultra-wide 4:1 input voltage range, efficiency as high as 83% and continuous short circuit protection by input current limiting. 14 models operate from (4:1) input voltage ranges of 10 to 40 VDC or 18 to 72 VDC and provide tightly regulated outputs of 3.3, 5, 12, 15, ±5, ±12 or ±15 VDC. All models are packaged in a compact, low profile 2” X 2” X 0.4” metal case.

TRIM UP Trim output voltage up by connecting an external resistor between Pins 4 and 5. Use the following equation. Reference Table 1 for variable A. Radj-up = Example: A Δ% - 24 (kΩ) If we want to trim 5% up for 12V output units, where A = 1.97, Δ % = 0.05 Radj-up = 1.97 0.05 - 24 kΩ = 15.4 kΩ Table 1.
