3 Terms and Definitions
The following terms and definitions apply to this standard.
3.1
Provide energy to the power input AC voltage.
3.2
External power supply may affect the amount of any of its properties.
3.3
When other influences remain unchanged, since the impact of the steady-state values \u200b\u200bof one or several quantitative changes within a predetermined range, which leads to a stable output of
Variety.
3.4
Since the AC voltage source within the specified range changes caused by stable output volume changes.
3.5
Since the load current is varied within a predetermined range, stable output caused by volume changes.
3.6
Since the AC voltage source and the load within their rated range change simultaneously, which leads to a stable output volume changes.
3.7
When the ambient temperature changes 1 ℃, the maximum amount of change in output power stability.
