... Figure 1: Connection and jumper settings for 80A / 220V bi-directional meter module SPEC-0088 (REV. 1) CONNECTORS ON MODULE The PM2002DP module connects directly to live and neutral on SCK1. The module is referenced to live and should be kept in mind when connecting test equipment to the module. The current is measured by the shunt on the top of the PCB. The left terminal of the shunt is connected to live ...

... PM2002DP ANALOG SECTION The analog (metering) interface described in this section is designed for measuring 220V/80A with precision better than Class 1. The most important external components for the SA2002D integrated circuit are the current sense resistors, the voltage sense resistors and the bias setting resistor. The resistors used in the metering section should be of the same type so temperature effects are minimized ...

... PM2002DP CT TERMINATION RESISTOR Provision is made for the use of a current transformer on the module. The existing shunt needs to be removed and the current sense resistors will have to be recalculated for the specific current transformer. The voltage drop across the CT termination resistor at rated current should be at least 20mV. ...
