led lighting

led lighting

program overview

at present, if constant dc power supply is adopted for led lighting lamps, which are more and more widely used, it is theoretically possible to achieve constant lighting without stroboscopic. but in fact, due to the lack of industry standards, the market competition is fierce and disordered, and the market is full of low-quality led lamps, especially indoor low-power led lamps, which also have stroboscopic problems. in order to obtain a pure constant current source, the led driving power supply is the key to ensure that the led lamp does not flash. at present, led power supply can fully meet the requirements of no stroboscopic.

single phase 10a voltage dips generator

model：vdt s10

voltage dips/sags, short interruptions are caused by failures of the power grid and power facilities or sudden large changes in loads. in some cases, there will be two or more consecutive dips or interruptions. voltage changes are caused by continuous changes in the loads connected to the grid. if the eut cannot respond in time to changes in the power supply voltage, it may cause malfunctions. voltage dips generators are used to evaluate the performance of electrical and electronic equipment when subjected to voltage dips/sags, short interruptions, and voltage changes. products fully meet the requirements of standards iec/en 61000-4-11 and gb/t17626.11.

single phase 5kv burst generator eft s4

model：eft s4

in the circuit, such as from the switching transient process (cutting off inductive loads, bouncing relay contacts, etc.), it will usually interfere with other electrical and electronic equipment in the same circuit. this kind of interference is characterized by high amplitude, short rise time, high repetition rate and low energy. clusters of narrow pulses can charge the junction capacitance of semiconductor devices, which may cause circuit or equipment errors when accumulated to a certain extent. the burst generator determines a common reproducible evaluation basis for evaluating the performance of power supply ports, signal, control and grounding ports of electrical and electronic equipment when disturbed by electrical fast transient bursts. the products meet the requirements of new standards such as iec61000-4-4, en60100-4-4 and gb/t17626.4.
