Air Cooled Resistor Products Wholesale - Rata
Product Overview
1) Product overview
Product Features
- Rata air-cooled resistor is a high-density special-alloy, air-cooled resistor assembly built in an anodized aluminum shell (model-dependent 6063‑T3 / 6061). It is designed to deliver high power in a compact package (example dimension 120×120×30 mm) and supports resistance values from 0 to 100 Ω. Units are manufactured to international standards and can be matched with a DC fan; internal structure and voltage ratings are configurable to customer requirements.

Product Advantages
- Compact, high-power design that saves more than half the volume versus traditional resistors.
Application Scenarios
- Resistive element made from nichrome alloy with a low temperature coefficient (hot-state resistance change ≤ 10%).
- Wide adjustable resistance range (0–100 Ω) and modular connection for scaling power by adding or removing modules.
- Good air-cooling heat dissipation via aluminum shell and optional DC fan compatibility.
- Strong corrosion resistance and anodized, customizable exterior color.
3) Product value
- Space and weight savings for constrained installations (vehicles, equipment racks).
- Flexible, configurable resistance and power capacity allow one product family to meet varied application needs.
- Reliable thermal performance and low drift improve measurement accuracy and system stability.
- Robust construction and quality-controlled manufacture reduce downtime and lifecycle cost.
- Customizable appearance and connection options simplify system integration.
4) Product advantages
- Very high power density in a small footprint.
- Low resistance drift at operating temperature due to nichrome element.
- Modular architecture enables easy power scaling and replacements.
- Corrosion-resistant, heat-dissipating aluminum housing with anodized finish for durability.
- Designed and produced to international quality standards with configurable electrical stress and voltage options (e.g., withstand 1.5 kV/60s, 3 kV/60s; short-term impact 10 kW/1 s; fault power 2 kW).
5) Application scenarios
- New energy vehicles and buses (charging systems, regenerative braking test loads).
- Shore power systems and converter/rectifier equipment.
- Test-load fields and power electronics testing benches.
- Military and aviation applications requiring compact, rugged resistive loads.
- Any air-cooled installations needing scalable, high-density resistors (can be used with DC fans for enhanced cooling).
