Loading Rheostat 3.5KW Bank Three Phase
Product Code : SCL-PLE-11833
The StemAids 3.5kW Three-Phase Loading Rheostat Bank is an industrial-grade electrical testing station engineered for the empirical study of three-phase power systems, balanced/unbalanced loading, and alternator regulation. Capable of dissipating 3,500 Watts of total power, this unit features three independent resistive banks that can be configured in Star (Wye) or Delta arrangements. Manufactured to ISO 9001:2015 standards, it is a critical asset for University Engineering departments and Technical Institutes for quantifying the performance of three-phase generators and motors.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- Polyphase Interface: Facilitates student understanding of three-phase power distribution, supporting the study of Phase Voltage (Vph) vs. Line Voltage (VL) in Star/Delta configurations.
- Balanced Load Quantification: Enables the physical measurement of neutral current; learners apply equal resistance to all three phases to verify that In=0 in a balanced system.
- Unbalanced Analysis: Supports the analysis of phase shifts and neutral displacement; students evaluate the impact on a three-phase generator when loads are distributed unevenly across the phases.
- Thermal Management Evaluation: Allows students to evaluate the heat dissipation requirements of industrial machinery, fostering a deeper understanding of cooling efficiency and safety in high-power environments.
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade, reinforced seaworthy crating (ISPM-15 compliant). The internal heavy-duty ceramic cores are secondary-bolted and cushioned to prevent mechanical fracture during maritime transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and detailed three-phase wiring schematics for Star and Delta setups.
- Durability: Tropicalized design featuring anti-corrosive powder coating and high-temperature silicone-insulated internal wiring, ensuring longevity in demanding laboratory or industrial workshop environments.
Direct OEM Sourcing Advantages
Procuring the StemAids 3.5kW Three-Phase Loading Rheostat directly ensures vertical manufacturing control:
- Phase Matching Precision: Every bank is individually calibrated to ensure that the resistance steps are identical across all three phases, which is critical for accurate "balanced-load" experiments.
- In-House Safety Testing: Every unit undergoes a 4-hour "burn-in" test at full 3.5kW load to verify that the cooling fans and insulation systems exceed industrial safety margins.
- Direct Factory Spares Availability: Guaranteed availability of replacement ceramic tubes, industrial-grade switches, and cooling fans to maximize the long-term ROI of institutional assets.
- Manufacturing Control: Direct oversight of the earthing (grounding) system ensures that the metallic chassis remains at zero potential even during high-current unbalanced phase testing.
