The above information is based on pumping clean water at rated voltage and ambient temperature. The supply voltage must be within the range specified below. Flow rates were collected at the maximum discharge pressure and 360spm. The flow rate increases as the discharge pressure decreases.
Allowable ambient temperatur range:             0-40°C
Allowable fluid temperature      range:               0-40°C
Allowable voltage deviations:   ±10% in the rated voltage range
Noise level:                                     65dB at 1m (A scale)

Note 1: Maximum voltage from the EJ to an external contact = 15V at a current up to 3 mA. When using relays, the current should always remain below 3 mA
.
Note 2: If the maximum allowable input pulse rate is exceeded, these pulses will not be counted or stored.
Note 3: Damage may occur if the operating voltage exceeds 264V.
