Self-shifting range circuit
The digitally controlled attenuator uses the DG201 four analog switch as the input step attenuation switch for the A/D converter. The switch is controlled by digital logic. The digital logic detects the overrange and underrange information of the A/D converter and turns off the corresponding attenuator path. The circuit is suitable for the Silicon Knicks LD110/111 or LD111/114 A/D converter.


3000W Three Phase AC Source System

Product Introduction:

APM 3 Phase Ac source SPS300VAC3000W is capable of delivering 3000VA of output power.3 Phase Ac Power Source is a 3-phase output programmable AC Power Supply which provides with high power density. With high speed DSP+CPLD control, high frequency PWM technology, active PFC design, It is able to provide not only stable DC/AC output power, but also 3-phase / 1-phase output. This AC power supply is featured with high power density, high reliability and high precision, meanwhile it possesses operation interface of touch screen and keys manually. It is able to analog output normal or abnormal power input for electrical device to meet test requirements, which is applicable to electric, lighting, aviation sectors, etc. It could be applied to enterprise`s production test as well.
