This standard adjusts the applicable content in SJ/T10541-1994 "General Technical Conditions for Anti-Interference AC Stabilized Power Supply" and SJ/T10542-1994 "Test Methods for Anti-Interference AC Stabilized Power Supply". The main changes are as follows:
——Added common terms in this standard: apparent power (see 3.1.1), active power (see 3.1.2), reactive power (see 3.1.3), load power factor (see 3.14) , load capacity (see 3.15). ——Added the load capacity classification of power supply (see 4.8.1 Table 2) ——Added the calculation formula and measurement method of pulse load power factor (see 4.8.1). ——The lower limit value of the mean time between failures (MTBF) is clarified: MT
