The Duomo FP45 range of current monitors has been developed to monitor the current drawn by fan motors in ventilation systems. To comply with BS6173:2001 for Commercial Catering Establishments it is necessary to prove that extract and supply air fans are operational before making gas available to the kitchen appliances. The FP45S has two level switching points. Low - to prove that the fan is on and High - to ensure that the motor is drawing the expected load under normal conditions. Some fan motors have a larger load than the FP45S current monitor can tolerate directly (10A max.). In such cases current transformers are used to reduce this current and still allow an accurate indicated value to be displayed on the FP45S.
