Product Overview
- Model S 500 L — a 500 kW, three-phase (400 Vac, 50 Hz) AC resistive load bank designed for outdoor operation with an integral protective canopy.
- Rugged carbon-steel powder-coated enclosure (IP54), copper busbars, stainless louvers, resistive load elements and four universal casters for portability.
- Control options include manual toggles/push-buttons, PLC/software, and hand‑held device; control connections via fast connector, GN connections and RJ45.
Product Features
- High power capacity: 500 kW with fine step resolution (1 kW) using a multi-step configuration (1+2+2+5+10+10+20+50+100×4).
- Robust environmental performance: IP54 rated, operating range −20°C to +60°C, altitude rating up to 2000 m.
- Cooling & airflow: heavy‑duty axial fans, horizontal airflow, approx. 1250 CM/min.
- Safety & protection: thermal emergency cut-out, airflow switch, fan overload protection, emergency stop, fuses on load steps.
- Durable construction: carbon steel powder coat, copper busbars, insulation test 700 Vac, load element tolerance ±2.5%.
- Practical installation: AC contactor switching, 4 casters, compact enclosure dimensions for outdoor site use.
Product Value
- Provides a safe, repeatable and measurable way to simulate electrical loads for commissioning, acceptance testing and preventive maintenance.
- Reduces risk of field failures by validating generators, UPS/inverters, and power distribution before deployment.
- Supports compliance and performance verification for mission‑critical systems (data centers, marine, defense, renewables).
- Enables accurate capacity verification and conditioning of backup systems to improve reliability and uptime.
- Helps absorb excess power in microgrids/renewables for stability and demand-response testing.
Product Advantages
- Purpose-built for outdoor and harsh environments (canopy + IP54) compared with indoor-only units.
- High resolution and flexible load stepping (1 kW) combined with large total capacity (500 kW) for precise testing across a wide range.
- Multiple control modes (manual, PLC/software, handheld) and modern connectivity (RJ45) for versatile operation and integration.
- Strong protection and cooling design for safe continuous operation up to high ambient temperatures.
- Manufactured with quality controls and backed by Deyang Rata Technology’s after-sales support, competitive pricing and on‑time delivery.
Application Scenarios
- Generator testing: full‑load verification, acceptance tests, and dynamic step‑load stability checks for diesel, gas and turbine gensets.
- UPS and battery systems: UPS discharge and autonomy tests, inverter capacity verification and preventive maintenance.
- Data centers and critical facilities: commissioning load simulation, utility-to-backup transfer testing and cooling/distribution validation.
- Renewable energy & microgrids: inverter performance testing and absorbing excess generation for grid stability/demand response.
- Marine, offshore and defense: onboard power system verification and compliance testing to standards (DNV, ABS, Lloyd’s).
- Factory testing and commissioning: quality assurance for engines, turbines and electrical equipment prior to delivery.
