1. The output voltage can be programmed to a voltage lower than 50V; however, performance below 50V is not
specified.
2. Add ±2.5VDC when Filter 1 or Filter 2 is enabled.
3. Regulation specifications apply for greater than 25VDC (with full load), or 50VDC (with no load). Below these
values, the unit may not regulate correctly.
4. Peak-to-peak values are within five times the RMS value.
5. Add 2.5µA offset when Filter 1 or Filter 2 is enabled.
6. Times apply with the current limit set to 105% of full scale.
