Suitable for
both continuous high power and short time overload
dissipation applications
-
It can be customized as High
Current Resistors to handle
very High Loading Current, up to hundreds
of Amperes.
-
They can be
used
as Load
Resistor for
load bank.
-
All resistance values are made
according to the customer's application needs.
-

and high resistance ranges
-
Support Vitreous Enamel
coating for harsh conditions
applications
-
For
very small resistance requirement, please
state the maximum current and loading time. Different
Voltage can cause different resistor current.
In turn different raw
materials and production process are needed to withstand
the load current and heat.
