Inductive Load
Product Code : SCL-PLE-11825
The StemAids Inductive Load is a precision-engineered laboratory instrument designed for the empirical study of AC circuit dynamics and lagging power factor. Unlike purely resistive loads, this apparatus introduces inductive reactance (XL) into a circuit, allowing students to observe the phase shift between voltage and current. Manufactured to ISO 9001:2015 standards, it is an essential component for University-level electrical engineering labs for quantifying the performance of transformers, motors, and power factor correction systems.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- Reactance Interface: Facilitates student understanding of the relationship between frequency, inductance, and opposition to AC flow (XL=2πfL), supporting Advanced Electromagnetism modules.
- Phase Shift Quantification: Enables the physical study of AC waveforms; learners apply oscilloscopes to measure the lagging current phase angle (?) relative to the supply voltage.
- Power Factor Analysis: Supports the analysis of "Real" vs. "Reactive" power; students evaluate how an inductive load lowers the power factor and practice calculating the necessary capacitance for correction.
- Transient Evaluation: Allows students to evaluate back-EMF and inductive "kick" when a circuit is interrupted, fostering a deeper understanding of circuit protection and relay design.
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade seaworthy crating (ISPM-15 compliant). Due to the high density of the copper windings and steel core, units are secured with heavy-duty internal bracing to prevent mechanical shifting during maritime transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and an impedance-frequency calibration chart.
- Durability: Tropicalized design featuring vacuum-pressure impregnated (VPI) windings to ensure moisture resistance and noise-free operation (no humming) in high-humidity laboratory environments.
Direct OEM Sourcing Advantages
Procuring the StemAids Inductive Load directly ensures vertical manufacturing control:
- Low-Loss Core Design: We use premium-grade laminations to ensure that the inductive load behaves as close to "pure" inductance as possible by minimizing internal resistive heating.
- Precision Step Matching: Direct oversight of the coil-tapping process ensures that each step provides the exact rated inductance for repeatable experimental results.
- Direct Factory Spares Availability: Guaranteed availability of replacement selector switches, heavy-duty terminals, and internal cooling fans to maximize the long-term ROI of laboratory infrastructure.
- Manufacturing Control: Direct oversight of the insulation testing (Dielectric Strength) ensures the highest level of operator safety during high-voltage AC experiments.
