Description:

Waterproof power supply is used in the case of dust-proof with waterproof grade IP67, with multiple protections such as short circuit, over current, overload and so on.

We have IP67 Waterproof series two types--engineering type and ultra thin type, Widely used in LED industrial project, communications power, aerospace, industrial control systems, post communications, medical equipment and other industrial and commercial fields. 

Engineerinbg type waterproof led drivers mainly include 12V and 24V series with 20W, 30W, 40W,50W, 60W,80W,100W,120W,150W, 200W,

250W, 300W,400W, 450W, 500W, 550W, 600W.

Mainly for LED spotlights, LED light strips, LED street lamps, LED light box, LED module light , LED signboard light, LED bulbs, LED buried lights, LED sky lights, LED flat lights, LED wall washing lights and other LED lamps to provide driving capacity. The most important feature is that it is waterproof and can be used outdoors without fear of rain, fog, direct sunlight and other harsh environments.

Specifications:

Notices:

1. Input voltage should be within the specified voltage range (for examples: input voltage 220VAC).

2. Prohibited to be used in the high temperature environment, power port is the thermal vents, wind 50CM range, please do not place other objects, make sure that the power should have good thermal dissipation space environment.

3. Prohibited to install power supply in the presence of flammable materials (such as wood products, flammable plastic, etc), to stay away from petrol stations or where prohibited Fireworks.

4. Accurate calculation of load power, peak use, suggested user to use power supply based on power 80% load, do not overload.

5. Power supply have built-in short circuit protection function, when output short circuit, the power will automatically enter the status. Power off after 1 minute and then power on.

6. For safety, properly grounded, the output power cable must be ≥2.5mm²

7. Strictly in accordance with the position indicated by the output terminals of the power supply. It must be firm, check the output line and prohibited to be reversed (input "220VAC" main line, output "+" loaded for positive cathode, output "-" load for negative cathode).

8. Power firm installed vertically (vertically in a place easy to wire the power supply, cover to cover, to be water proof)

Classification according to the circuit structure

(1) Resistance, capacitor step-down mode:

Through the capacitor step-down, in flashing use, due to the role of charge and discharge, the instant current through the LED is great, easy to damage the chip. It is easily affected by the voltage fluctuation of the power grid, and the power supply has low efficiency and reliability.

(2) Resistance step-down mode:

Through the resistance step-down, the interference of the grid voltage change is large, it is not easy to make a regulated power supply, step-down resistance to consume a large part of the energy, so this power supply mode of power efficiency is very low, and the reliability of the system is also low.

(3) Conventional transformer step-down mode:

Power supply volume is small, weight is heavy, power efficiency is also very low, generally only 45% ~ 60%, so generally rarely used, reliability is not high.

(4) Electronic transformer step-down mode:

The power efficiency is low, the voltage range is not wide, generally 180 ~ 240V, ripple interference is large.
