Rata Load Banks Rata Load Bank for Sale
Product Overview
- Rata’s 1250 kW resistive AC three‑phase load bank designed primarily for outdoor use (canopy), intended for generator load testing and system commissioning. Rated voltage 415 VAC (3φ, 4‑wire) with control voltage 380 VAC. Physical size 2220×1420×2100 mm and weight ~1850 kg. Export‑ready with wooden case/pallet packing.
Product Features
- Pure resistive load (1250 kW) using 8020 Ni‑Cr alloy finned resistors for stable dissipation.
- Local panel switching control (option to request remote PC control per enquiry).
- Tin‑plated copper bar for load power connection and terminal connections for control wiring.
- Horizontal air discharge with axial fans; noise
- IP54 protection on the unit and waterproof cover on the local panel; designed for export and field deployment.
- Certified CE, ISO9001:2015, ISO14001:2015, ISO45001:2018.
Product Value
- Provides a reliable, repeatable and safe way to apply full resistive loads for performance verification, acceptance testing and preventive maintenance of generators and power systems.
- Reduces commissioning time and operational downtime by allowing controlled, on‑site load simulation.
- Durable, exportable design lowers total cost of ownership through robust components and proven manufacturing quality.
Product Advantages
- High capacity (1250 kW) in a single outdoor cabinet for large generator sets and system tests.
- Quality resistors (Ni‑Cr finned), secure copper bar connections and weather‑resistant enclosure for long service life in field conditions.
- Compact, transportable build with export packing and global sales/support network.
- Manufactured by a technically experienced team (Rata) with strong quality systems and international certifications.
- Flexible control options and customer‑driven configuration (voltage/frequency, indoor/outdoor, control mode).
Application Scenarios
- Generator load testing, commissioning and acceptance testing for diesel/gas gensets.
- Routine maintenance and capacity verification of standby power systems, UPS and switchgear.
- Load simulation during factory tests, powerplant and substation commissioning.
- Site testing for rental power, microgrid verification, and industrial/remote power installations.
