Based Mounted Shunts FN Series This base mounted shunt provides an alternative to the panel meter series at ratings below 500A. Its black moulded base gives the additional mechanical strength required for many applications as well as providing a means of mounting. It is equally suitable for laboratory work for use as a component in electronic equipment. Features Accuracy 0.25% Insulated Base mounting Temperature Coefficient 0.002% per 1C. Specification Installation Ratings: 1-500A Accuracy: 0.25% Outputs: 50mV (or) 100mV Refer to Factory for other outputs Temperature Coefficient: Shunts can be mounted horizontally or vertically. For maximum heat dissipitation, mount horizontally with the element in free air and ensure that the equipment housing permits adequate ventilation. 0.002% per C overall Construction Warning The manganin resistance element is hard soldered into conservatively rated brass end blocks. These are mounted on to an insulating, moulded base, drilled to provide fixing holes. Shunts are not fully insulated and protection against accidential contact may be necessary in order to comply with Health and Safety regulations.
