Sodium Lamp Transformer 35W
Product Code : SCL-PLE-11757
The StemAids Sodium Lamp Transformer (35W) is a specialized electromagnetic ballast engineered to provide the high starting voltage and stabilized operating current required for Low-Pressure Sodium (LPS) and High-Pressure Sodium (HPS) lamps. Optimized for University-level optics and spectroscopy, this unit serves as the essential power interface for monochromatic light sources used in Newton's Rings and Michelson Interferometer experiments. Manufactured to ISO 9001:2015 standards, it ensures flicker-free operation and thermal protection for sensitive light-source housings.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- Monochromatic Source Interface: Facilitates the generation of a stable 0nm and 589.6nm (D-lines) light source, supporting Wave Optics and Interference modules.
- HID Ignition Quantification: Enables the physical study of gas discharge, allowing learners to apply the principles of high-voltage ionization to understand the "warm-up" phase of HID lamps.
- Current Stabilization Analysis: Supports the analysis of why discharge lamps require a ballast to maintain a constant current once the gas becomes conductive.
- Spectral Purity Evaluation: Allows students to evaluate the difference between polychromatic (white) and monochromatic (sodium) light in diffraction and refraction experiments.
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade seaworthy crating (ISPM-15 compliant) featuring high-density foam stabilization to protect the heavy electromagnetic core and internal capacitors from vibrational stress.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and Electrical Safety Test Reports.
- Durability: Tropicalized design featuring vacuum-impregnated windings and moisture-resistant insulation, ensuring a high MTBF (Mean Time Between Failure) in high-temperature laboratory environments.
Direct OEM Sourcing Advantages
Procuring the StemAids Sodium Lamp Transformer directly ensures vertical manufacturing control:
- In-House High-Pot Testing: Every unit undergoes insulation resistance testing at 2kV to ensure absolute user safety when dealing with ignition pulses.
- Batch-Tested for Uniform Reliability: Each transformer is burn-in tested with a 35W load for 8 hours to verify thermal stability and noise-free (no hum) performance.
- Direct Factory Spares Availability: Guaranteed availability of replacement ignitors and specialized connecting cables to maximize long-term laboratory ROI.
- Manufacturing Control: Direct oversight of the core lamination ensures high efficiency (>90%), reducing wasted heat and ensuring the longevity of the sodium lamp bulb.
