LED Power Supplies and Transformers (12V/24V)
Even the most expensive LED strip will quickly fail if connected to a low-quality power supply. Cheap transformers are the reason lighting flickers, buzzes, and often overheats, posing a fire hazard. VIDEX 12V and 24V power supplies are the industrial-grade heart of your lighting system, ensuring long-term (TCO) safety.
VIDEX engineering advantages:
- Smart IC Protection: Unlike cheap analogs, VIDEX blocks feature a built-in intelligent microchip. It ensures instant shutdown in case of a short circuit, current overload, or overheating.
- Flicker-Free Technology: Cheap transformers cause light pulsation that triggers headaches. VIDEX guarantees stable DC current without flickering.
- IP20 and IP67 Protection Classes: We offer perforated blocks for indoors (IP20) and fully hermetic transformers (IP67) for safe use outdoors or in wet rooms.

Q: How to engineeringly calculate the precise required power supply capacity (W) for an LED strip installation?
Q: What are the physical consequences of ignoring the 20% Safety Margin rule?
Q: How does the heat dissipation mechanics differ between passive (Fanless) and actively cooled transformers?
Q: In what room design conditions are Ultra-Slim (IP20) form factor power supplies necessary?
Q: How do VIDEX power supplies protect a large LED matrix array from 230V grid anomalies?
A: Use the formula: (Total strip length in meters) × (Load per meter W/m) × 1.2 (Safety reserve). For example, for 5 meters of strip at 14 W/m (70W load), multiplying by 1.2 yields the minimum required transformer capacity of 84 W.
Q: What are the physical consequences of ignoring the 20% Safety Margin rule?
A: Operating a transformer continuously at 100% load causes its internal capacitors to heat above their nominal temperature. This drastically accelerates electrolyte drying, reducing the power supply's lifespan from 5 years to a couple of months, and can cause inductive coil whine.
Q: How does the heat dissipation mechanics differ between passive (Fanless) and actively cooled transformers?
A: Passive units transfer heat to the external environment via an aluminum radiator, providing a 0 dB noise level (suitable for bedrooms). Active units (above 350W) use a built-in fan for cooling, creating constant mechanical noise, so they must be mounted in closed technical shafts.
Q: In what room design conditions are Ultra-Slim (IP20) form factor power supplies necessary?
A: These are ultra-thin current converters (often under 20 mm), designed for extremely narrow mounting locations. They physically fit into furniture gaps, behind mirrors, or in shallow aluminum profile niches where a standard industrial format block would not fit.
Q: How do VIDEX power supplies protect a large LED matrix array from 230V grid anomalies?
A: A high-class IC chip with OVP (overvoltage), OCP (overcurrent), and SCP (short circuit) protection is integrated into transformers. In the event of critical anomalies, the circuit instantaneously blocks the DC output, preventing severe lighting equipment from burning out.
