Product number: R634B
The optional digital wattmeter comprises a 3½ digit true power AC wattmeter and current transformer. The current drawn by the compressor is sensed by a current transformer and sent as a mA signal to the wattmeter.
AC volts are also monitored by the wattmeter and processed to display compressor energy consumption rate (Watts). The addition of the wattmeter enables students to extend the range of experiments by allowing the compressor power to be monitored. The wattmeter is fitted to the panel fascia in place of a blanking plate.
