BL0932

BL0932 Dual Measurement Watt-hour Meter IC BL0932 Application Note DESCRIPTION BL0932 IC is the main chip widely used for single-phase anti-steal electronic watt-hour meters. BL0932 is the modified version of BL0931. It keeps the main features of BL0931, such as better linearity, wide range of dynamic measurement, against potential shift, as well as provides real anti-steal of electricity power. The watt-hour meters made of BL0932 have better reliability. BL0932 is a special large integrated circuit used for static electronic watt-hour meter. It uses silicone barrier BICMOS process with advanced circuitry, dual measurement of wattage, excellent performance, safe & reliable. The circuit is plastic/ceramic packaged dual in line with 20 pins. PIN ASSIGNMENT FEATURES Have real function of anti-steal of electricity, precisely measure both positive and negative wattful power and integrate the electrical energy at the same direction. Good linearity, wide dynamic operating range. Prevent from potential shift Fast pulse output for computer data processing, slow pulse output will directly drive the pulse motor For used both as single-phase and three-phase watt-hour meter Compatible with BL0931 for outline and pin signal Good reliability with more than 20 years life of time.
