Ac Load Bank Rata Load Bank Wholesale - Rata
Product Overview
- Model: S 500 L (Rata). A 500 kW, three‑phase resistive (PF 1.0) AC load bank designed for outdoor operational use with a purpose-built canopy and IP54-rated control chamber.
- Rated for 400 Vac, 50 Hz, 3‑phase, four‑wire (star) connection. Compact skid: 1715 × 1261 × 1632 mm, ~850 kg, fitted with 4 universal casters for mobility.
- Provides precise, repeatable load simulation for commissioning, maintenance and acceptance testing of power systems.
Product Features
- High resolution, flexible loading: step configuration 1+2+2+5+10+10+20+50+100×4 with 1 kW step resolution.
- Cooling & airflow: heavy‑duty axial fans, horizontal airflow ~1250 CM/min, stainless louvers.
- Robust outdoor protection: IP54 enclosure, carbon‑steel powder coated canopy, rated ambient operation −20°C to +60°C and up to 2000 m altitude.
- Electrical construction: copper busbars, AC contactors for load switching, resistive load elements, insulation test 700 Vac.
- Safety & control: thermal emergency cut‑out, airflow switch, fan overload protection, emergency stop; control via manual toggle/push buttons or remote PLC/software; control power 400 Vac 3ph 5‑wire; connectors include fast connectors, GN and RJ45.
Product Value
- Enables safe, repeatable, measurable load testing to validate generators, UPS, inverters and power distribution before deployment—reduces commissioning risk and avoids costly failures in service.
- Supports preventive maintenance (UPS discharge, generator acceptance), performance verification and regulatory/compliance testing, improving asset reliability and uptime.
- High resolution and configurable steps allow accurate stability and step‑load testing to replicate real operational profiles.
- Durable outdoor design extends applicability to harsh environments, reducing the need for ad hoc shelters or additional protection.
Product Advantages
- Human-centered design with operations and servicing in mind, improving ease of use compared with typical load banks.
- High reliability and engineered protections lower total cost of ownership and maintenance downtime.
- Precision manufacturing and factory quality testing from Rata ensure consistent performance and predictable monthly output for customers.
- Broad functionality (manual and remote control, fine load resolution, robust environmental ratings) offers flexibility across many test scenarios.
- Portable yet heavy‑duty build balances mobility with rugged outdoor suitability.
Application Scenarios
- Generator testing: full‑load verification, acceptance tests, step‑load stability checks for diesel, gas and turbine gensets.
- UPS & battery systems: UPS discharge/autonomy tests, inverter capacity verification, preventive maintenance of backup power.
- Data centers & critical facilities: commissioning IT loads, utility‑to‑backup transfer testing, validating cooling and distribution capacity.
- Renewable energy & microgrids: inverter performance validation (solar, wind, hybrid), absorbing excess power for grid stability and demand response.
- Marine & defense: onboard power system verification and classification society compliance (DNV, ABS, Lloyd’s).
- Factory testing & commissioning: manufacturer QA for engines, turbines and electrical systems prior to delivery.
