It is no longer necessary to use combinations of transducers to achieve a power measurement and control system.
A Texmate Tiger 320 Series DI-503 meter, installed with a single-phase power input module, calculates and displays volts, amps, Hz, watts, watt hours, and power factor from a single-phase 2 or 3-wire voltage and current input.
The optional relay, analog and serial outputs can be configured from all the above parameters to interface with a control or alarm system.
Power factor gives an accurate measure of load change, particularly at low to medium loads, where current is dominated by it's magnetizing element. Where prompt action is required the optional relays in the Tiger 320 Series meter can be used for protection against broken belts, pump cavitation, conveyor stalling and general overloads.
