DC regulated power supplies are developing toward higher precision.
(1) Voltage regulation rate SV. Voltage regulation rate is an important indicator of the stability performance of a DC regulated power supply, also known as the stabilization coefficient or stability factor. It characterizes the degree of stability of the output voltage VO of the DC regulated power supply when the input voltage VI changes. It is usually expressed as the percentage of relative change between the input and output voltages per unit output voltage. Formula for voltage regulation rate.
(2) Current regulation rate SI. Current regulation rate is a major self indicator that reflects the load capacity of a DC stabilized power supply, also known as the current stability coefficient. It characterizes the ability of a DC stabilized power supply to suppress fluctuations in output voltage caused by changes in load current (output current) when the input voltage remains constant. Under specified conditions of load current changes, the current regulation rate of a DC stabilized power supply is usually expressed as the percentage of the output voltage change per unit output voltage. Formula for current regulation rate..
(3) Ripple suppression ratio SR. Ripple suppression ratio reflects the ability of a DC regulated power supply to suppress the mains voltage introduced at the input terminal. When the input and output DC regulated power supply components of the DC regulated power supply remain unchanged, the ripple suppression ratio is often expressed as the ratio of the peak to peak value of the input ripple voltage to the peak to peak value of the output ripple voltage, usually in decibels, but sometimes it can also be expressed as a percentage or directly as the ratio of the two.
(4) Temperature stability K. The temperature stability of an integrated DC stabilized power supply is determined by the percentage of relative changes in the output voltage of the DC stabilized power supply within the specified operating temperature range Ti * (Tmin ≤ Ti ≤ Tmax). Temperature stability formula.
