Om0065 issue 5 page 4 of 21 1 introduction this manual describes the operation and maintenance of the mag-03psu power supply unit. The unit provides a battery backed power supply of ± 12 v for the mag-03 series of three axis fluxgate magnetic sensors. It also contains filters for the analog outputs ...
Om0065 issue 5 page 5 of 21 5 cables cables can be supplied to connect any of the mag-03 series of sensors to the mag-03psu. Details are given in the operation manual for the sensor. The cable carries the supply voltage to the magnetic field sensor; 0 v connection is via the screen. Analog signals a...
Om0065 issue 5 page 6 of 21 8 battery charging a 12 v dc (nominal unregulated) output mains adaptor for battery charging purposes is supplied as an accessory. Before use ensure that this is of the appropriate voltage for the local mains supply, either 110 v or 220 v/240 v ac, 60 hz or 50 hz. As an a...
