DC12V 200W/400W Steady Voltage IP67 Water-Resistant LED Switching Power Source for Point-Type LED Lights
LED Power Supply Description
A power unit is an electronic apparatus that transforms electric power from a source into the designated voltage, current, and frequency required by electrical or electronic gear. It ensures steady and dependable power provision, shielding devices against voltage variations, spikes, or excessive loads. Power units can be classified based on their operational characteristics: linear power units, which utilize transformers and voltage regulators for stable output but are lower in efficiency; and switch-mode power supplies (same core term, industry-standard), which adopt high-frequency switch-mode circuits to attain greater efficiency and compact dimensions, rendering them well-suited for contemporary electronic devices.
LED Power Supply Features
Sustains a steady output voltage regardless of variations in input voltage or changes to the load, guaranteeing uniform operation of connected devices. This is essential for sensitive electronic components such as microprocessors.
Gauges the proportion of output power to input power. High-efficiency variants (commonly used in switch-mode power supplies) reduce energy waste in the form of heat, cutting down on operational expenses and cooling requirements—this is crucial for industrial equipment and portable devices.
Specifies the maximum current a power supply can deliver without sustaining harm. It must match or surpass the requirements of the connected equipment to prevent overloads.
Comprise protective measures against short circuits, overvoltage, overcurrent, and overheating. These features shield both the power supply and the devices it powers from damage, boosting overall reliability.
Many modern power supplies accommodate a broad input voltage spectrum, making them fit for worldwide application in regions with different mains voltages.
Linear power supplies provide low output interference, making them ideal for audio equipment or high-precision instruments. Meanwhile, advanced switch-mode models use filtering to lessen electrical disturbance.
