Q:What is the linearity of switching power supply
Different power supply, linear adjustment rate is different Constant pressure source: Linear adjustment rate: the rate of change of the output voltage within the specified input voltage range; ΔV / V = (V - V1) / V * 100% Load rate: change in load within the specified range, change rate of output voltage; ΔV / V = (V-V1) / V * 100% A constant current source: Linear adjustment rate: the rate of change of the output current within the specified input voltage range; ΔI / I = (I - I1) / I * 100% Load regulation: change in load within the specified range, change rate of output current; ΔI / I = (I-I1) / I * 100%
Q:How to transform the switching power supply, the original AC 220 input into DC 84-100 input output unchanged
It is difficult to change, you can consider the use of ready-made DC-DC converter
Q:Your company's switching power supply through what channels to purchase?
Hello, now on the market power varies, the choice of power directly determines the product itself is good or bad, good power mainly to see the program, device platform, production technology, testing standards and a series.
Q:How to 12V3A switching power supply external voltage regulator potentiometer
Ordinary single-bit potentiometer If your switching power supply itself is with the regulator then the board should have a voltage regulator potentiometer that removed in a resistance and the same as the original can be a motor when the two can only use a block Fast on it
Q:Will a 12V10A switching power supply with a few 12V2A surveillance camera?
12V10A switching power supply with 5 12V2A surveillance camera. General 2 * 1 power line transmission 300 meters is no problem.
Q:How to check the switching power supply leakage current
Insulation tester (pressure value) Vin to GND Vout to GND Vin tested against Vout separately Test the voltage transferred to your power corresponding to the standard on the line. You will see the leakage current in the insulation tester display value.
Q:Will the switching power supply fake load how to calculate?
Switching power supply fake load, the main purpose is to overcome the no-load or light load output instability. And the output is unstable, the primary D is too small, the energy is not open is the secondary overshoot voltage or feedback current is too large, forced IC to reduce D;
Q:Is switching power and transformer the same thing?
Switching power supply is used to control the switch through the circuit for high-speed pass and cut off. The conversion of direct current into high-frequency alternating current is provided to the transformer for voltage change to produce the required group or groups of voltages. The transformer is voltage-converted by magnetic coupling. The switching power supply is in a field and can not be used instead of the transformer. Output without transformer, rectifier, filter, regulator way pure.
Q:High power high frequency switching power supply with what rectifier
Input level with ordinary rectifier can be, the output stage recommended with silicon carbide diodes
Q:Ups and high frequency switching power supply
UPS and high-frequency switching power supply The main difference: High-frequency switching power supply, refers to the use of power switching devices, at high frequencies through the converter for energy conversion power. High-frequency switching power supply (also known as switching rectifier SMR) through the MOSFET or IGBT high-frequency operation, the switching frequency is generally controlled in the 50-100kHz range, to achieve high efficiency and miniaturization. UPS is the uninterruptible power supply, there are batteries and inverter circuits and control circuit, when the mains power supply is interrupted, the UPS control circuit will detect and immediately start the inverter circuit work, so that the output of 220V AC, On the use of electrical appliances continue to work for some time, so as to avoid the loss of electricity caused by interruption. Switching power supply is 220V AC, into the required DC it can have multiple sets of DC output, the main rectifier filter circuit, the control circuit, because of its high efficiency, small size, well protected, widely used in electronic equipment. Such as computers, television and so on.
We have various advanced equipment, such as wave soldering and reflow soldering machine, RoHS testing, environmental testing system, etc. Only top international brand components are adopted for our key parts to ensure long lifetime and high reliability. Each unit is given full load burn-in test.
