Analog Ammeter Panel Type 50A AC DC
Product Code : SCL-PLE-11706
The StemAids Analog Ammeter (50A AC/DC) is a heavy-duty, moving-iron laboratory instrument engineered for the empirical study of high-current electrical systems. Optimized for Secondary, Vocational (TVET), and Electrical Engineering curricula, this panel-mounted meter facilitates the quantification of both alternating and direct current up to 50 Amperes. Manufactured to ISO 9001:2015 standards, it provides a ruggedized, "no-latency" visual indicator for verifying load characteristics and circuit protection in institutional power laboratories.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- Moving-Iron Sensing Interface: Facilitates student visualization of electromagnetic attraction and repulsion forces, supporting Electrical Engineering Module 101.
- RMS Quantification: Enables the physical study of AC waveforms, allowing learners to apply the meter to measure effective current without the need for complex digital sampling.
- High-Current Circuit Analysis: Supports the analysis of load behavior in motors, heaters, and power supplies, providing immediate feedback on current surges.
- Scale Linearity Evaluation: Allows students to evaluate the "square-law" scale characteristics inherent in moving-iron instruments compared to linear moving-coil types.
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade seaworthy crating (ISPM-15 compliant) featuring anti-vibration internal stabilization to protect the delicate pivot-and-jewel movement during transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and Wiring/Installation Guides in English.
- Durability: Tropicalized design featuring moisture-proof coil insulation and anti-static window treatments for reliable performance in varied climates.
Direct OEM Sourcing Advantages
Procuring the StemAids Analog Ammeter (50A) directly ensures vertical manufacturing control:
- In-House Precision Calibration: Every meter is batch-tested against a calibrated current source to ensure accuracy across the full 50A scale.
- Batch-Tested for Uniform Reliability: Every unit undergoes a high-voltage dielectric test to ensure user safety during high-load AC demonstrations.
- Direct Factory Spares Availability: Guaranteed availability of replacement terminal nuts, mounting brackets, and external shunts to maximize long-term laboratory ROI.
- Manufacturing Control: Direct oversight of the hairspring and pivot assembly ensures low-friction movement and long-term zero-point stability across all production lots.
