The category of dc regulated power supply and choose

Dc stable power supply according to the habit can be divided into chemical power supply,linear

regulated power supply stability and switch mode power supply,they respectively have different types:Chemical power source,we used ordinary dry-cell batteries,lead-acid batteries,nickel cadmium,nickel metal hydride,lithium ion batteries are belong to this category,each have their advantages and disadvantages.With the single phase asynchronous motordevelopment of science and technology,and the intelligent battery;In rechargeable battery materials,American researchers found that manganese a iodide,use it can produce cheap,small,discharge time is long,many times after charging still maintain good performance and environmentally friendly rechargeable batteries.Linear stable power supply,linear regulated power supply is a common feature is that it is power device adjusting pipe work in the linear area,stable output by adjust the voltage drop between the tube.

Due to adjust the tube static loss is big,need to install a large radiator to electric motors 12

voltheat it.And because the transformer work in power frequency (50 hz),so the weight

is bigger.This kind of power source advantage is high stability,small ripple,high reliability,easy to make it more road,continuous adjustable output of finished products.The disadvantage is that large volume,heavy,efficiency is relatively low.Such a stable power supply and there are 5kw permanent magnet generator many,from the output properties can be divided into www.dongfeng-motor.com regulated power supply and current regulator and voltage regulator,steady into voltage steady flow (bistable) power supply.From the point of the output value can be divided into fixed point switch to adjust output power,band and several continuous adjustable potentiometer.From the output indicator can be divided into pointer on type and digital display type and so on.
