The LM339 voltage comparator chip contains four independent voltage comparators, which are common integrated circuits for the LM339 pin map. Various voltage comparator circuits and oscillator circuits can be conveniently constructed using lm339.
The LM339 integrated block is equipped with four independent voltage comparators. The voltage comparator features: 1) small offset voltage, typically 2mV; 2) wide supply voltage range, single supply is 2-36V, dual supply voltage ±1V-±18V; 3) wider internal resistance limit for comparison signal source; 4) large common mode range, 0~(Ucc-1.5V)Vo; 5) differential input voltage range is large, large It can be equal to the power supply voltage; 6) The output potential can be flexibly and conveniently selected.
The LM339 manifold is packaged in a C-14 package with external and pinout arrangements. Due to the flexible use and wide application of LM339, the world's major IC manufacturers and companies have launched their own four comparators, such as IR2339, ANI339, SF339, etc. Their parameters are basically the same and can be used interchangeably.

600V DC Electronic Load

600v DC Electronic Load can be switched quickly between different values in the same operating mode, including CC dynamic mode, CV dynamic mode, CR dynamic mode and CP dynamic mode, CC/CR high speed dynamic mode up to 50kHz. This function is suitable for transient test of power supply, test of battery protection characteristic and battery pulse charging etc. Dynamic mode test has continuous mode, pulse mode and toggle mode.

Additionally , programmable DC electronic load can also have 200V DC Electronic Load and 1200V DC Electronic Load for more options.
