Calculate your maximum kWh/pulse (pulse weight) value
Make sure the required pulse rate does not exceed the maximum pulse rate for the digital output.
Example pulse weight calculation
For a maximum load of 1600 kW and a pulse rate of 2 pulses per second, calculate the kWh/pulse value as follows:
Convert 1600 kW load into kWh/second:
- (1600 kW)*(1hr) = 1600 kWh
- (1600 kWh)/(3600 sec) = (X kWh)/(1sec)
- X = 0.444 kWh/sec
Calculate the kWh required per pulse:
- (0.444 kWh/sec)/(2 pulses per second) = 0.222 kWh/pulse
If using KYZ Output Mode, adjust for the KY giving one pulse per 2 transitions if necessary.
- (0.222 kWh/pulse)/(2) = 0.111 kWh/pulse
