About Powerohm Resistor Systems
Powerohm resistor systems are used in demanding applications where controlled energy dissipation, motor braking, electrical protection, and dependable system performance are essential to daily operations.
Control Concepts Dallas supports Powerohm components used throughout crane and hoist systems, variable-frequency-drive applications, mining operations, power systems, oil and gas facilities, and other demanding industrial environments.
Our technicians evaluate resistor condition, system sizing, electrical connections, enclosure integrity, cooling, and overall application requirements. We can help identify compatible replacements and determine whether system adjustments, upgrades, or additional braking components are needed.

The Repair Process
When a Powerohm resistor or braking system develops a problem, Control Concepts Dallas evaluates the component and surrounding operating conditions to determine whether the resistor is damaged, incorrectly sized, or being affected by another system issue.
Our technicians review system voltage, resistance requirements, drive specifications, braking torque, duty cycle, electrical connections, enclosure condition, ventilation, and environmental exposure.
Once the cause is identified, we determine whether direct replacement, system resizing, additional braking equipment, retrofit, or another corrective action is the most practical solution.
Preventative maintenance can help reduce unexpected resistor and braking-system failures.
