Electrical data

Operating voltage (“SUPPLY”)

• 100…240 V AC 50/60 Hz

– current consumption at 100 V AC: 0.8 A

– current consumption at 240 V AC: 0.3 A

– tolerance: ± 10 %

– integrated protective fuse: a slow blow 2 A fuse. The fuse cannot be replaced and

is integrated in the power supply.

or

• 20…30 V DC

– ± 10 % tolerance

– filtered and regulated

– connection to main supply: permanent (through external SELV and LPS power

supply)

Power consumption

Max. 96 VA

Medium data

Fluid

Water without particles: drinking water, industrial water

Fluid pH range1.)

pH 4…pH 9

Fluid conductivity

• > 50 µS/cm if there is no pH sensor cube

• > 100 µS/cm if there is one pH sensor cube

Temperature of the fluid sample

+ 3…+ 40 °C (+ 37…+ 104 °F)

Pressure of the fluid sample

Refer to See data sheets of the sensor cubes and accessories, use the lowest pressure

Flow rate of the fluid sample

Min. flow rate: 6 l/h per installed sensor module, so with e.g. 3 sensor modules the min.

flow rate is 6 + 6 + 6 = 18 l/h due to parallel installation.
