Low voltage electrical apparatus

Low-voltage Apparatus

Program overview

Power supplies are widely used in modern electronic products, which need to have certain anti-interference ability, isolation and protection functions. Different countries and regions have a series of certification standards for various power supplies entering the market to ensure the quality of power products. ITech has a rich product line of power test instruments, including AC and DC sources, AC and DC loads, power analyzers, and its9500 power module automatic test system.

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 8Kv lightning surge generator sur S8

Model：SUR S8

The impact of lightning (indirect lightning) in nature and voltage changes caused by large switch switching in power supply lines on power supply lines and communication lines is particularly large, and the impact on products may be destructive. The lightning surge generator is used to evaluate the performance of the equipment when it is subjected to high-energy disturbance from the power line port and other signal line ports. The product meets the requirements of new standards such as iec61000-4-5 and gb/t17626.5.

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.
