What Is Driving Power?
Drive power is a kind of power converter, which can be divided into constant current, regulated, pulse drive, and AC drive according to the drive mode. The drive power supply has high reliability and has functions such as overcurrent protection and open circuit protection. At present, there are two kinds of power sources, one is isolated power source, and another is non-isolated driver power supply.
Isolated Power Source VS Non-isolated Driver Power Supply
DIFFERENT RISKS OF ELECTRIC SHOCK
Non-isolated driver power supply: The load end of the non-isolated power supply is directly connected to the input end. The non-isolated power supply will introduce the high voltage of the AC power supply to the load end, thus causing the danger of electric shock.
Isolated power supply: The load end and the input end of the isolated power supply are indirectly connected, so there is no danger of electric shock when touching the load
DIFFERENT DRIVING EFFICIENCY
Non-isolated driver power supply: The drive efficiency of a non-isolated power supply is higher
Isolated power supply: The drive efficiency of isolated power supply is low
DIFFERENT COST
Non-isolated driver power supply: The circuit structure of non-isolated power supply is AC/DC step-up or step-down circuit scheme, so the relative circuit is simple, and the cost is relatively low
Isolated power supply: The current isolation schemes are mostly AC/DC Flyback circuit schemes, so the relative circuit is more complex and the cost is higher
In practical daily life, both LED non-isolated driver power supply and LED isolated power supply are commonly used in different occasions. As a product that can be used safely by the end user, the reliability of the insulation and isolation must be considered. As a complete product, the parts of the product surface that are accessible to the user must be isolated so that no one can be electrocuted. In terms of the whole system of the product, isolation is inevitable, the difference is only in the location where the isolation is set. Some designers use isolated transformer designs, so they can simplify heat dissipation and lamp cover design. If a non-isolated driver design is used, reliable insulation requirements must be considered in the construction of the lamp housing. Therefore, as power driver power driver both isolated and non-isolated solutions have always existed.
What about UPSHINE driving power?
There are many series of driving power in UPSHINE, such as 0-1v dimming power supply, WIS series driving power, DALI power supply, KSI series driving power, 4 Philips Certa Drive series, tridonic LC SR SNC series, etc. All of them can differ from isolated power supply and non-isolated power supply, and some are built-in power supply and external power supply.
In the following, there will pick 2 kinds of driving power from UPSHINE to introduce.
