. The additional effects of temperature change
to output accuracy will be ±0.012%RD / K out of the range of rated
Under rated working condition, the frequency change of power supply will not affect technical
performance indications of current and voltage. The power factors between voltage change of
power supply to output power of AC current and voltage should meet following requirements.
