Loading Rheostat 1.2KW Bank
Product Code : SCL-PLE-11831
The StemAids 1.2kW Loading Rheostat Bank is a high-performance variable resistive load engineered for the empirical study of power sources, small generators, and electrical machine characteristics. Capable of dissipating up to 1,200 Watts of electrical energy as heat, this unit provides a controllable load to quantify the performance and regulation of DC and AC power supplies. Manufactured to ISO 9001:2015 standards, it is a staple for University-level physics and electrical engineering laboratories where precise, incremental loading is required for data modeling.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- Power Dissipation Interface: Facilitates student understanding of the conversion of electrical energy into thermal energy, supporting Thermodynamics and Basic Circuit Theory.
- Regulation Quantification: Enables the physical study of "Voltage Regulation"; learners apply incremental loads to a power source to determine the percentage drop in terminal voltage.
- Ohmic Relationship Analysis: Supports the analysis of V=IR and P=V2/R; students evaluate how changing the resistance of the bank inversely affects the current drawn from the supply.
- Load Matching Evaluation: Allows students to evaluate the Maximum Power Transfer Theorem by adjusting the rheostat bank to match the internal resistance of the source.
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade seaworthy crating (ISPM-15 compliant). The internal ceramic cores are secured with vibration-dampening mounts to prevent fracture during rough maritime or overland transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and a detailed operation manual specifying maximum current limits for each resistive step.
- Durability: Tropicalized design featuring high-temperature insulation and anti-tarnish hardware, ensuring the unit maintains its resistance accuracy in high-humidity laboratory environments.
Direct OEM Sourcing Advantages
Procuring the StemAids 1.2kW Loading Rheostat Bank directly ensures vertical manufacturing control:
- Thermal Stability Calibration: Every resistive element is aged and tested to ensure a low temperature coefficient, meaning the resistance remains stable even as the unit heats up during a 3-hour lab session.
- Step-Load Precision: Direct oversight of the internal wiring ensures that each switch engages a precisely calculated resistance value for repeatable experimental results.
- Direct Factory Spares Availability: Guaranteed availability of replacement ceramic tubes, resistive wire coils, and high-current switches to maximize the long-term ROI of institutional assets.
- Manufacturing Control: Direct oversight of the grounding (earthing) system ensures that the outer ventilated chassis remains safe for student contact during high-wattage experiments.
