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 = A Δ% - 24 (kΩ) Example: 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. Output Voltage A 3.3V 5V 12V 15V 0.75 1.25 1.97 2.07 TRIM DOWN Trim output voltage down by connecting an external resistor between Pins 3 and 4. Use the following equation. Reference Table 2 for variable C and D. Radj-down = C Δ% - D (kΩ) Example: If we want to trim 2% down for 5V output units, where C = 1.25, D = 26.5, Δ % = 0.02 Radj-down = 1.25 0.02 - 26.5 kΩ = 36 kΩ Table 2.
