2. Ripple & Flicker-Free Performance

  • G-24096-DWJ: 0.7V-pp ripple and 20KHz PWM flicker-free output, making it ideal for professional lighting applications.
  • ETF-24096-TD: Higher ripple (7.98V-pp) may cause LED flickering, affecting visual comfort.

✅ Recommendation: For high-quality, flicker-free lighting, G-24096-DWJ is the better option.

3. Energy Efficiency & Heat Dissipation

  • G-24096-DWJ: Efficiency ≥84.6%, reduces heat generation and lowers energy costs.
  • ETF-24096-TD: Efficiency ≥81%, slightly lower, leading to higher energy consumption.

✅ Recommendation: If you want to prioritize energy savings and long-term cost-effectiveness, choose G-24096-DWJ.

4. Compatibility & Input Voltage Range

  • G-24096-DWJ: Supports 100-277VAC, making it compatible with global power grids.
  • ETF-24096-TD: Limited to 100-130VAC, restricting its application.

✅ Recommendation: If you need a universal power supply for different regions, G-24096-DWJ is the best choice.

5. Power Factor & Harmonic Distortion

  • G-24096-DWJ: PF ≥0.99, THD ≤11.6%, ensuring better power utilization and lower grid interference.
  • ETF-24096-TD: PF ≥0.94, THD ≤28%, meaning higher electrical noise.

✅ Recommendation: For commercial projects and stable power networks, G-24096-DWJ is the preferred choice.

Final Recommendation: Which Power Supply Should You Choose?
