Product Information

Description

The Zero Cross Nanoshield allows you to identify the moment when the AC voltage from the power grid crosses the zero-volt line. This can be used in the following applications:

• Dimming of incandescent, halogen or other dimmable lamps
• Smooth control of high power loads, minimizing noise on the main power line (also check the Triac Nanoshield)
• Detection of presence or lack of electric power

CAUTION

This module was designed to connect directly to the AC grid power, and its misuse might cause ELECTRIC SHOCK and FIRE. Only use this module if you already have prior experience with mains AC circuits, and carefully follow the safety recommendations at the bottom of this page.

Features

• Centralized output pulse on zero crossing with constant 1 millisecond duration, either for 127V or 220V
• Optically coupled output to isolate AC voltages from other DC circuits and components
• Efficient detection circuit that generates a lot less heat than solutions based on optocouplers connected directly to power resistors
• Output selection between 5V or 3.3V output via solder jumper (default: 5V)
• 17 options for the output pin, selectable via solder jumper (default: D2)
• Output status indicator LED
