1000W Plate Shape High Power Wirewound Resistors,Voltage and Current Regulation
Structure:
1.ZB series Plate-shaped Wirewound Resistor is made of nickel chromium,constantan or new constantan alloy wire and other high-quality alloy wires wound on the iron plate with surface electroplating treatment, aluminum plate with surface anodizing treatment or mica plate. Ceramic devices are used to separate the winding wire from the base plate, so that the winding wire can drive over the base plate evenly and regularly, playing a good role in fixation, insulation and heat dissipation.
2.Aluminum plate or iron plate matrix has no fixed form and can be made according to customer requirements,breaking the limitations of the industry.
3.Single unit with multi-resistance/ Multi-terminals also available;
4.Non-inductive & variable type on requests;
5.Working voltage and Nominal resistance value are related to Ohm’s law.
Features:
1.Plate-shaped Wirewound Resistor with stable resistance,small
change rate,high power,strong overload capacity.The corrugated
winding mode (increasing resistance and eliminating parasitic
inductance)and non-inductive winding mode can be realized, which
can not only eliminate the parasitic inductance of the resistor,
but also improve the heat dissipation .
2.It can also be flexibly changed according to customer
requirements to make a single resistor with more than 2 resistance
values or multiple resistors in series and parallel.
3.Support precision resistance tolerance requirement.
