Resistive Load Banks Ac Load Bank Supplier Factory
Product Overview
- Model S60L is a portable 100 kW resistive AC load bank designed as a workhorse for data‑center and generator testing. It is compact (353 × 764 × 660 mm), weighs about 80 kg on four castors, and is built to validate UPS, generators, PDUs and cooling systems. Rated for three‑phase operation (star, 4‑wire) at 400 Vac (50 Hz); supports common voltage scenarios with required derating.
Product Features
- Power: 100 kW maximum; load step resolution 1 kW.
- Load element tolerance: ±3% (accurate simulation of light/medium/heavy loads).
- Control: local HMI push‑buttons, remote control, or software (Nexus‑1).
- Load switching: 3‑pole AC contactors and fuses on steps (no arcing, fast switching).
- Cooling: forced air horizontal flow, ~720 CMM, finned tubular resistors, rated -20°C to +50°C, altitude
- Protections: thermal emergency cut‑out, airflow switch, fan overload protection, emergency stop; control chamber IP23.
- Practical items: copper busbars for load connections, quick mains connectors, optional control voltage configurable to draw 3‑phase 400 Vac from the generator under test.
Product Value
- Provides a reliable and accurate means to validate and commission power infrastructure (UPS, gensets, PDUs, cooling), ensuring voltage and frequency stability under realistic loads.
- Portable and easy to deploy for on‑site field testing or tight data‑center spaces, reducing downtime and eliminating the need for large permanent installations.
- Flexible control and the option to use the generator as the auxiliary control power simplifies logistics at remote test sites.
Product Advantages
- Industry‑oriented balance of power, portability and modularity (100 kW common size).
- High resolution and accuracy (1 kW steps, ±3%) for precise load profiles and generator stability testing.
- Robust safety and switching design (fused steps, contactors, multiple protections) that minimizes risk of arcing or EMI impact on the site.
- Strong cooling and environmental ratings for stable operation in typical indoor/outdoor test conditions (IP23, broad temperature range).
- Experienced manufacturer (Deyang Rata Technology Co., LTD) with quality control and international supplier background.
Application Scenarios
- Data center commissioning, periodic UPS and PDU testing and capacity validation.
- Generator load bank testing, performance and stability verification, and field commissioning.
- Cooling system validation under thermal loads.
- Rental fleets and mobile test teams needing a compact, transportable load bank.
- Factory acceptance tests, power system troubleshooting, and preventive maintenance in commercial/industrial sites.
