Hello there! Welcome to the official website of Foshan Dongfo Lighting Appliance Co., Ltd.
Series parallel connection of LED lamp board wide voltage: In order to make the rated input voltage range of LED wall washer AC85-265V, the method of series parallel connection of LED board is very important. Because the current power supply is usually a non-blocking step-down power supply, when a wide voltage is required, the output voltage should exceed 72V, the input voltage range can reach 85-265V. In other words, the number of series does exceed 23 character strings. The wall washer manufacturer advised to connect too much in parallel, otherwise the rated current is too large the heat is serious. The recommended values are 6 / 8 / 12. The total current does exceed 240 mA. There is also a wide voltage plan, which is to use L6561 / 7527 to increase the voltage to 400V, then reduce the voltage, which is equivalent to two switching power supplies, the price is twice that. The plan is cost-effective has no market.
Precautions for outdoor installation of LED high-power wall washer: fix the lamp with screws; connect the bulb to the power cord wrap it with waterproof tape; pay attention to the upper limit of the number of strings when installing; confirm that all devices are faulty the power can be connected.
