1.2. Technical data
General
- Alternative voltages are stated as r.m.s. values.
- Only values with tolerances and or numerical values are guaranteed.
- Deviations (in% or ppm) apply to the adjusted value.
- Temperature coefficients apply within temperature range.
- All specifications are met after a warming-up time of 30 minutes.
