Description
Analog Ground. The voltage to this pin should be mid-way
between V and V .
Positive supply voltage. The voltage to this pin is typically +2.5V
if a shunt resistor is used for current sensing or in the case of a
current transformer a +5V supply can be applied.
Negative supply voltage. The voltage to this pin is typically -2.5V
if a shunt resistor is used for current sensing or in the case of a
current transformer a 0V supply can be applied.
Analog Input for Voltage. The current into the A/D converter
should be set at 14µA
voltage sense input saturates at an input current of ±25µA peak.
Inputs for current sensor. The shunt resistor voltage from each
channel is converted to a current of 16µA
The current sense input saturates at an input current of ±25µA
peak.
This pin provides the connection for the reference current setting
resistor. A 24k resistor connected to V set the optimum
operating condition.
Pulse rate output. Refer to pulse output format for a description
of the pulse rate.
Direction output. The direction of the energy flow is indicated on
this output.
Voltage sense zero crossover. The FMO output generates pulses
on energy rising edge of the mains voltage.
Leave pins unconnected.
