Frequently Asked Questions

ZHPOWR focuses on medium and high power industrial LED driver power supply, covering the full range of 20W-1500W, including: Non-isolated constant current waterproof power supply (IP67, 3.75KV voltage, suitable for mining lights, tunnel lights) Intelligent dimming power supply (3-in-1 dimming technology, compatible with DALI/0-10V/PWM) Ultra-low temperature customized power supply (-40℃~85℃ limit environment verification)

The wattage of LED fixtures commonly referred to by LED lighting manufacturers refers to the total input power of the fixture. This value can vary significantly due to the efficiency differences of the internal power supply under different operating conditions. The wattage of the power supply referred to by power supply manufacturers refers to the maximum output power of the power supply. The relationship between the two can be expressed by the following formula: Fixture total power × Power supply efficiency = Power supply output power.

To assess whether a power supply can be used for making flicker-free lighting fixtures, check the size of the output ripple current. If the ripple current is less than 10%, the lighting fixture can be flicker-free. If it is between 10% and 20%, the fixture will have low-frequency flicker. If the ripple current exceeds 20% to 100%, the power supply can only be used for making lighting fixtures with visible flicker.

The safety shell temperature of a product refers to the highest operating shell temperature at a specified location that is allowed by safety certifications, without considering the long-term lifespan of the product. The warranty shell temperature refers to the maximum operating shell temperature of the power supply, which is specified to ensure the product can operate reliably and stably within the warranty period.
