The Power Pro from Trinity is an easy-to-use, cost effective electrical power meter that offers all the basic measurement capabilities required to monitor an electrical installation. In addition to measuring the instantaneous parameters, it also measures accurately all three energies, and also demand, thus helping to measure and control energy costs.
Over the basic metering, it optionally provides two relay outputs, RS485 port supporting MODBUS RTU protocol, dual source metering and THD measurements.
The relays are site programmable for parameter of action, and the value on which to operate.
The CT primary and secondary, PT ratio and installation type are site selectable, thus making it possible to use the meter in all types of three phase installations.
