VAR TRANSDUCER
(self-powered)
2: 110 V / 1 A AC
3: 220 V / 1 A AC
Functions & Features
4: 220 V / 5 A AC
• Providing a DC output signal in proportion to AC reactive
power
5: 220 V / 380 V / 1 A AC (3-phase / 4-wire)
6: 220 V / 380 V / 5 A AC (3-phase / 4-wire)
7: 110 V / 190 V / 1 A AC (3-phase / 4-wire)
8: 110 V / 190 V / 5 A AC (3-phase / 4-wire)
(220 V in code 5 and 6, and 110 V in code 7 and 8
are phase voltage)
• 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
• No auxiliary power source required
