High power resistors
Solutions for high dissipation, load, discharge, current limiting, test benches and industrial power electronics equipment.
Supply of high power, high voltage, braking, wire wound, variable, adjustable and water-cooled resistors for demanding industrial applications.
TOT POWER Iberia helps select power resistors for dissipation, braking, load, discharge, protection, testing and maintenance of power electronics equipment.
Industrial resistors for braking, dissipation, load, discharge, high voltage and high power applications.
Power resistors are critical components in systems where electrical energy must be dissipated, current limited, voltages balanced, capacitors discharged, load tests performed or regenerative energy absorbed.
They are widely used in frequency converters, variable speed drives, servo drives, power supplies, load banks, rectifiers, railway systems, renewable energy, industrial machinery, lifting systems, welding equipment and test systems.
TOT POWER Iberia supports engineering teams, machinery manufacturers, industrial maintenance companies and technical purchasing departments that need to source a resistor compatible with their application.
We select industrial resistors according to power rating, voltage, resistance value, construction technology, cooling system, duty cycle and mounting conditions.
Solutions for high dissipation, load, discharge, current limiting, test benches and industrial power electronics equipment.
Resistors for voltage dividers, discharge, balancing, high voltage power supplies, instrumentation and systems with high DC buses.
Resistors for absorbing regenerative energy in drives, servos, lifting systems, cranes, traction, industrial machinery and controlled stop cycles.
Robust resistors for industrial applications requiring overload capability, stability and good thermal dissipation.
Rheostats, adjustable resistors and variable loads for test benches, laboratories, commissioning and load simulation.
Compact high-power solutions when air cooling is not sufficient or when available installation space is limited.
High power resistors are designed to operate with high levels of thermal dissipation and current. They are suitable for applications where electrical stability, overload capability and thermal management are critical factors.
We can study wire wound, encapsulated, cemented, thick film, non-inductive or special resistor solutions depending on the resistance value, required power and mounting format.
High voltage resistors are intended for circuits where high voltage levels must be handled while maintaining stability, insulation and reliable performance under demanding electrical stress.
They are commonly used in voltage dividers, high voltage power supplies, discharge circuits, capacitor balancing, instrumentation and measurement systems.
Braking resistors are used to dissipate the energy regenerated by electric motors during deceleration, braking or controlled stop processes.
Selection must consider drive power, DC bus voltage, required resistance value, braking energy, duty cycle, available ventilation and environmental conditions.
Wire wound resistors are a robust solution for industrial applications requiring good overload capability, stability and thermal dissipation.
They can be studied in tubular, ceramic, vitreous enamelled, cemented, non-inductive or metal-mounted formats, depending on the electrical and mechanical requirements of the equipment.
Variable and adjustable resistors allow the resistance value to be manually modified or a load to be configured according to the needs of the equipment, test bench or test procedure.
They are suitable for laboratories, load banks, power supply testing, equipment commissioning and simulation of operating conditions.
Water-cooled resistors are designed for very high power applications or reduced installation spaces, where air cooling is not sufficient or not convenient.
They allow large amounts of heat to be removed through a liquid cooling circuit, provided that hydraulic design, flow rate, pressure and electrical safety are correctly defined.
Power resistors are used in sectors where electrical energy must be safely and repeatedly dissipated, controlled or simulated.
TOT POWER Iberia supports technical departments, engineering companies, machinery manufacturers, industrial maintenance teams and technical buyers who need to locate an equivalent power resistor, replace an existing reference or define a solution for new equipment.
We can work from an existing reference, a photograph, a drawing, a datasheet or the basic electrical data of the application.
The more technical information available, the more accurate the resistor selection or compatible alternative search will be.
Yes. This page is focused on product type and application. TOT POWER Iberia can study power resistors and compatible alternatives according to the customer’s technical data, without limiting the proposal to a specific brand.
Yes. We can study alternatives based on the original reference, photograph, resistance value, power rating, dimensions, construction technology and operating conditions.
It is advisable to know the drive power, DC bus voltage, required resistance value, braking cycle, operating time, available ventilation and environmental conditions.
Yes. We can study special solutions when enough data is available to define power, resistance, voltage, format, fixing, cooling and service conditions.
When the power to be dissipated is high, the available space is limited or air cooling is not sufficient to keep the temperature within safe operating limits.
Send us the reference, photograph, datasheet or operating specifications. We will review the most suitable option for your industrial application.
