2.4 Power Connection
The C500 series can be powered from DC or AC supplies.
2.4.1 DC Power
The C500 series requires a 12-24VDC power supply. The supply need not be regulated, provided that it is free
of excessive electrical noise and sudden transients. The C500 series can operate from good quality plug-packs
of sufficient capacity to drive both the indicator and the loadcells.
The case ground connection is available via the earth stake on the rear of the unit. The resistance measured
between the case of the indicator and the nearest earth point should be less than 2 ohms.
2.4.2 AC Power Module
There is an optional AC supply module which requires an AC input of 100-240VAC, 50-60Hz, ≈0.6A. Maximum
supply voltage variations should not exceed ±10% of the voltage range specified.
The AC supply module also provides a 12DC 0.5A(max) output. Attachment of the AC module is shown
below.
