DESCRIPTION
The BL6503E is a low cost, high accuracy, high stability, simple peripheral circuit electrical energy meter IC. The meter based on the BL6503E is intended for using in single-phase, two-wire distribution systems.
FEATURES
● High accuracy, less than 0.1% error over a
dynamic range of 3000 : 1
● Exactly measure the real power in the positive
orientation and negative orientation, calculate the
energy in the same orientation
● A PGA in the current channel allows using small
value shunt and burden resistance
● The low frequency outputs F1 and F2 can
directly drive electromechanical counters and two
phase stepper motors and the high frequency output
CF, supplies instantaneous real power, is intended for
calibration and communications
● The logic outputs REVP can be used to indicate a
potential orientation
● Low static power (typical value of 15mW).
● On-Chip power supply detector
● On-Chip anti-creep protection
● On-Chip voltage reference of 2.5V± 8% (typical
temperature coefficient of 30ppm/℃ ), with external
overdrive capability
● Single 5V supply
● Credible work, working time is more than twenty
years
