In real life, there are too many lighting products - they come in various forms, different types, and individual styles, dazzling the eye and overwhelming to behold! There are residential lighting products, commercial lighting products, and industrial lighting products, each with its own brilliance, playing significant roles in different scenarios, adding color to people's monotonous lives!

The surface-level diversity and vibrancy result from the hard work and dedication of countless lighting professionals! They exhaust their creativity in design and encounter various problems during installation and debugging, with each problem being newer than the last, always presenting unexpected challenges.

Demi Technology's HZA Series products give us more initiative and less unpreparedness in product applications! The HZA Series products feature 10 selectable frequency gears. In practical product applications, LED luminaire designs encompass many categories, and when dimming driver power supplies match different LED luminaires, there are requirements for output frequency magnitude. Different output frequencies effectively extend the lifespan of LED lights and can achieve excellent dimming effects based on actual situations!

Detailed explanation of Demi Technology's HZA Series products as follows:

‌Highlight 1:‌
Output PWM adjustment (can switch between different frequency outputs through rotary gear switch selection)

‌Highlight 2:‌
Features five dimming methods combined: TRIAC + 0/1-10V / Resistor / 10V PWM

‌Highlight 3:‌
Includes a fine-tuning voltage adjustment knob. +1V: Performs light decay compensation (solves the issue of luminaire light decay; by increasing voltage, the luminaire can restore optimal brightness and continue use). Simultaneously addresses voltage drop problems during installation wiring. Fine-tuning can act as a dimmer: When customers use it without connecting a dimmer, they can still adjust the brightness to a certain extent (e.g., in scenarios like advertising light boxes where customers generally don't need frequent dimming and set the desired brightness once).

‌Highlight 4:‌
Product features a 9-gear selectable output frequency rotary knob; 250Hz-20KHz selectable, meeting special frequency requirements for luminaires and customer needs (some luminaires cannot use excessively high frequency output, such as luminaires with built-in controllers or conversion circuits that cannot withstand high frequency input, which is also the main reason why some customers specifically require low frequency output. Regarding flicker requirements: frequency ≥3125Hz achieves flicker exemption, but within 16000Hz, higher frequencies result in greater resonance noise (frequency resonance noise typically manifests at output connection points or in output circuits, such as in track lights, magnetic track systems, etc.). However, when frequency > 16000Hz, frequency resonance noise becomes difficult for humans to perceive, with 20000Hz and above being optimal. Therefore, requirements for power supply output frequency have gradually increased in recent years (customizable if higher output frequency is needed).

‌Highlight 5:‌
Small size, light weight, saves transportation costs, easy installation

‌Highlight 6:‌
Housing material is aluminum, truly passes NEMA 4X, excellent heat dissipation. Currently, many integrated machine housings on the market are made of iron, which cannot truly pass NEMA 4X, and their heat dissipation is much poorer than aluminum. (Thermal conductivity of iron (solid) is 60 W/mK; Thermal conductivity of aluminum (solid) is 237 W/mK).

‌Highlight 7:‌
Features multiple mounting feet, allowing for side mounting, flat mounting, and vertical mounting, meeting customer installation needs in different scenarios.

‌Highlight 8:‌
Flip cover design, screw-free installation, saving time and labor for end-users during wiring, economical and more convenient.

‌Highlight 9:‌
Wide dimming efficiency range: 0.1~100% (depth), smooth dimming throughout, no noise, no flicker.

‌Highlight 10:‌
Strong compatibility! Almost compatible with popular leading-edge and trailing-edge TRIAC dimmers and systems, 0-10V dimmers and systems on the market.

‌Highlight 11:‌
High efficiency: Under the same functionality and power, Demi products' efficiency is 3-5 percentage points higher compared to similar power type products, effectively reducing temperature rise and extending product lifespan.
