Power monitoring system FPA90

measurementtransformer

Monitoring of power consumption on 3-phase motors etc. Metering voltages 3 x 380 V to 3 x 460 VAC Built-in current transformer for direct monitoring up to 80 A Selectable metering ranges from 0,1 kW to 70 kW Analogue outputs and pulse output for kWh Selectable divider and average function Made in accordance with the CE and EMC regulations C-mac FPA90 is monitoring the consumed power on symmetrical 3-phase loads like motors, etc. The unit has a built-in current transformer, making it possible to monitor loads up to 460 VAC - 80 A direct. The converter is connected to the same 3-phase supply voltage as the load, and one of the phases are let through the hole in the unit, for monitoring of the load current. The wanted metering range (in kW) is adjusted on 3 rotary switches on the front of the unit. The converter is supplied with analogue current and voltage outputs and a pulse output, and the outputs are in maximum, when the monitored power is the same as the selected metering range. All outputs are galvanically separated from the supply voltage. In addition the unit has 3 digital inputs for the selection of analogue output signal, pulse ratio and input filter. The input filter is used if the load is very unstable, in this way, the output signal is more stable. The unit is also supplied with 3 LED indications
