MODEL: LPFN
8: 110 V / 190 V / 5 A AC (3-phase / 4-wire)
Power Transducer Series L-UNIT
(220 V in code 5 and 6, and 110 V in code 7 and 8
are phase voltage)
POWER FACTOR TRANSDUCER
(self-powered)
[3] OUTPUT SIGNAL POLARITY
P: Negative in lag, positive in lead
Functions & Features
• Providing a DC output signal in proportion to power factor
• DC output containing little ripple is ideal for computer
input
M: Negative in lead, positive in lag
• Isolation up to 2000 V AC
