Voltage
• Measuring bidirectional power flow
• DC output containing little ripple is ideal for computer
input
• "Time division multiplication" method accepts distorted
waveforms
• Isolation up to 2000 V AC
• High-density mounting
Typical Applications
• Centralized monitoring and control of power management
system in a manufacturing facility or building
• SCR – Silicon Controlled Rectifier
