Shunts
Based Mounted Shunts
828 Series
Model 828 is a compact shunt of
commercial quality and is designed for
chassis mounting in electronic
equipment.
Specification
Model 828-92N
Installation
Shunts can be mounted horizontally or
vertically. For maximum heat dissipation,
mount horizontally with the element in free air
and ensure that the equipment housing
permits adequate ventilation.
Warning
Shunts are uninsulated and protection
against accidental contact may be necessary
in order to comply with Health & Safety
regulations.
Accuracy class: 1.0
When calibrated together
with an indicator, the overall
system accuracy is within
the instrument class.
Ratings: 100mA to 10A
Outputs: Standard output is 75mV
50, 60, 100 or 150mV are
available on request
Overload 1.2 x rated current
withstand: continuously 10 x rated
current for 5 seconds at
75mV
Temperature 0.002% per °C overall.
Coefficient:
Ambient Calibrated for 20°C, they
temperature: can be used in an ambient
range of -20°C to +60°C
Temperature rise: When mounted as
recommended in freely
circulating air, the
temperature rise should not
exceed 90°C at 75mV.

Shunts
Based Mounted Shunts
829 Series
Model 829 provides an alternative to
the 880 series at ratings below 100A.
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 or for use as a component in
electronic equipment.
Specification
Model 829-92M
Construction
The manganin resistance element is silver
soldered into conservatively rated brass end
blocks. These are mounted on to an
insulating, moulded base, drilled to provide
fixing holes.
The current terminals are substantial M8
studs fitted with locknuts and washers.
Connection of the potential leads is made by
M5 slotted hexagon screws.
Installation
Shunts can be mounted horizontally or
vertically. For maximum heat dissipation,
mount horizontally with the element in free air
and ensure that the equipment housing
permits adequate ventilation.
Warning
Shunts are uninsulated and protection
against accidental contact may be necessary
in order to comply with Health & Safety
regulations.

Shunts
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.

Temperature
Coefficient: 0.002% per °C overall
Construction
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.
Installation
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.
Warning
Shunts are not fully insulated and protection
against accidential contact may be necessary
in order to comply with Health and Safety
regulations.
