Inventronics Drivers IT 0-10 P67 All-Purpose Power Supply For Road Lighting

This Inventronics Drivers product boasts a maximum conversion efficiency of 96%, with standby power consumption of less than 0.5W.

Many people think that a few percentage points difference doesn't matter, but that's not the case. Let's take a 100W power supply as an example, assuming it's on for 10 hours a day, 365 days a year:

A 96% efficiency power supply has a self-loss of about 4W, consuming approximately 14.6 kWh per year.

A 92% efficiency power supply has a self-loss of 8W, consuming approximately 29.2 kWh per year. The difference of 4% means a single unit consumes an extra 14.6 kWh per year. Imagine a street with hundreds of lights! How much difference would that add up to in electricity bills over ten years? This is a worthwhile calculation.

Furthermore, this model has very low standby power consumption, less than 0.5W. Many projects now require dimming and time-based control, turning down or partially turning off lights at night. In these situations, standby power consumption is crucial. Small savings add up, especially in large-scale projects, and the long-term electricity savings are substantial.

One feature of the IT 0-10 P67 that I find quite useful is its true dimmable shutdown function.

What does this mean? With ordinary 0-10V dimmable power supplies, even at the lowest setting, the LEDs still retain a slight glow, a phenomenon known in the industry as "afterglow." Imagine dimming a street light at night; the light isn't completely off, remaining slightly lit, wasting electricity and affecting the dimming effect.

This Inventronics model is different. Once the dimming signal drops to a certain threshold, the Inventronics Drivers completely shut off the output, leaving the LEDs completely dark with no afterglow. We tested it, and it truly is completely dark after shutdown, a feature many similar models on the market fail to achieve.

Don't underestimate this detail. This function is crucial for smart lighting and time-of-use control projects. Furthermore, it supports Aux auxiliary power, allowing seamless switching between dimming and auxiliary power supply, greatly increasing flexibility during system integration.

The IT 0-10 P67 boasts IP66 and IP67 protection ratings. What does this mean? It means complete dustproof protection and the ability to withstand short-term immersion in water. It can withstand rain, humid environments, and even high-salt-fog environments like the sea. We checked its certifications, and it has mainstream certifications such as IEC, CB, ANSI, and SAA, eliminating the need for recertification for export to different countries, saving considerable trouble.

The voltage input range is 90 to 305Vac, a wide range. It can be used with domestic 220V, international 110V, and 277V, and is even suitable for areas with unstable voltage fluctuations. For global projects, one model can cover most countries and regions, simplifying inventory management.

Another easily overlooked point is its surge and lightning protection. Outdoor lighting is most vulnerable to lightning strikes; many power supply failures are caused by lightning surges.

In northern countries where winter temperatures drop to -30℃ or -40℃, even cold starts for ordinary power supplies are difficult. In southern countries where summer temperatures can soar to 60-70℃, components operating at such high temperatures for extended periods experience rapid lifespan degradation.

The IT 0-10 P67 has an operating temperature range of -40℃ to +65℃, which is quite wide. Furthermore, its lifespan is rated at 100,000 hours at a Tc of 70℃. What does this mean? It means that even at a casing temperature of 70℃, it can still guarantee 100,000 hours of lifespan. This is a relatively high figure in the industry; many power supplies in the same price range have a Tc of 60℃ or lower.

Having been a distributor for many years, we have a very intuitive understanding: for every 10-degree drop in temperature, the lifespan of electrolytic capacitors roughly doubles. Therefore, the quality of the heat dissipation design directly determines the lifespan of a power supply. Inventronics Drivers has indeed put a lot of effort into its heat dissipation structure; you can feel the solid construction of the metal casing in your hand.

Having worked in this industry for a while, you'll find that many things look similar when first installed, making it difficult to tell their quality. The real difference lies after three to five years.

This is mainly due to light decay and component aging. A good power supply maintains a stable output current, resulting in slower light decay of the LEDs; a poor power supply, after one or two years, will start to show inconsistent output, causing the LEDs to either overdrive and decay prematurely or underdrive and dim.

There's also the issue of long-term reliability. The outdoor environment is complex, with high temperatures, low temperatures, humidity, and voltage fluctuations-all factors that slowly erode a power supply. A power supply with good components and sufficient design redundancy will last longer.

• Urban road lighting, street light upgrades
• Industrial parks, factory lighting
• Parking lots, tunnel lighting
• Outdoor billboards, landscape lighting

If your project has high reliability requirements, you don't want frequent maintenance later, or you're doing export projects requiring full certification, this is a product to consider.
