Battery Eliminator AC/DC 12V 2A
Product Code : SCL-PLE-11847
The StemAids AC/DC Battery Eliminator is a versatile power workstation engineered to provide both Low-Voltage AC and Regulated DC outputs. This "Dual Output" capability makes it an indispensable tool for physics and electronics laboratories, allowing for the simultaneous study of transformer behavior (AC) and semiconductor biasing (DC). Manufactured to ISO 9001:2015 standards, this 2A-rated unit provides sufficient current to power electromagnetic coils, light banks, and complex digital circuits without the voltage instability inherent in chemical cells.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- Dual-Nature Interface: Facilitates student understanding of the fundamental difference between alternating and direct current, supporting the study of Waveforms and Phase.
- Rectification Quantification: Enables the physical study of conversion efficiency; learners apply the AC and DC outputs to a circuit to observe how a bridge rectifier and filter capacitor transform the signal.
- Ohmic Analysis: Supports the analysis of Impedance (Z) vs. Resistance (R); students can evaluate how the same 12V potential affects a coil differently in AC mode versus DC mode.
- Source Versatility Evaluation: Allows students to evaluate and select the appropriate power type for various components, such as using AC for transformers and DC for transistor biasing.
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade seaworthy crating (ISPM-15 compliant). The internal heavy-duty transformer is secured with lock-nuts and vibration-dampening washers to ensure structural integrity during transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and a factory test certificate verifying output accuracy across all voltage taps.
- Durability: Tropicalized design featuring vacuum-pressure impregnated (VPI) transformer windings and high-temperature internal wiring, preventing insulation breakdown in high-humidity climates.
Direct OEM Sourcing Advantages
Procuring the StemAids AC/DC Battery Eliminator directly ensures vertical manufacturing control:
- Isolation Integrity: Direct oversight of the transformer winding process ensures high galvanic isolation between the mains input and the low-voltage outputs, maximizing student safety.
- Synchronized Output Taps: We ensure that the AC and DC taps are perfectly synchronized at each rotary switch position, providing consistent reference points for comparative experiments.
- Direct Factory Spares Availability: Guaranteed availability of replacement rotary switches, silicon bridge rectifiers, and safety terminals to maximize the long-term ROI of the asset.
- Manufacturing Control: Direct oversight of the earthing (grounding) system and chassis ventilation ensures the unit remains cool and safe even when drawing a full 2A load for extended periods.
