DC power supply www.kayandz.com in quality to meet the following four requirements 1. Temperature stability Temperature stability K integrated DC power supply is the biggest change in the range of Ti under the DC power supply operating temperature percentage (Tmin≤Ti≤Tmax) relative change in the output voltage of the DC power supply. 2 Current regulation SI current self-regulation is a major indicator of the load capacity of the DC power supply, also known as the current stability factor. It is characterized by constant when the input voltage DC power supply fluctuations due to the load current (output current) output voltage changes caused by the rejection, under the conditions specified in the load current changes, usually in units of output voltage Percentage changes in the value of output voltage DC power to represent the current regulation. 3. SV Voltage Regulation Voltage regulation is an important indicator to characterize the performance of the DC power supply regulator merits, also known as voltage coefficient or the stability factor, which characterizes the change when the input voltage VI DC power supply output voltage VO degree of stability, usually expressed as a percentage relative change in the input and output voltages of the unit output voltage. 4 ripple rejection ratio SR ripple rejection ratio reflects the input of the DC power supply for their ability to inhibit the introduction of mains voltage when the input and output DC power supply DC power supply components shall remain unchanged, ripple rejection Often compared to the input ripple voltage peak - peak output ripple voltage peak - the ratio expressed in decibels, said general use, but can sometimes be expressed as a percentage, or directly represented by the ratio of the two. http://www.kayandz.com power inverter power supply, DC power supply manufacturers http://www.agjixie.com shears, shears, hydraulic shears tilting vacuum http://www.hhnhj.com kneading machine, kneading machine http://www.szyx1990.com full height turnstiles, swing gates
