SMLSeries frequency interconversion power supply
Three-phase 400HZ input three-phase 50HZ output frequency mutual rotation
◇In many occasions, it is often encountered a hybrid system composed of military products and industrial-grade test and drive systems. In such systems, the problem of interface power incompatibility is often encountered. The blind use of special test or measurement equipment is restricted by factors such as cost and effectiveness, especially in the field conditions, which are prone to errors, so it is necessary to use two sets of power supply of intermediate frequency and power frequency. The SML series interconversion power supply is designed to solve this kind of problem. It can realize any switching between various input and output frequencies of 50HZ-60HZ-400HZ. As an embedded power supply, it forms a sub-system with various industrial-grade products in the system, which ensures the reliability of the whole system and saves a lot of basic costs.
◇Specially designed for military equipment
It is specially designed for the power supply of the air conditioner for a certain type of equipment, and has passed various inspections by the Aerospace Science and Industry Defense Technology Research and Test Center.
◇Purified output power quality
Double conversion technology provides pure and reliable sine wave power output.
◇Fast instantaneous response speed
For 100% unloading/loading, the output load regulation rate is stable at ±1% (linear load) within 10mS response time.
◇Strong overload capacity
100% full-load long-time delay is allowed; when the instantaneous load capacity exceeds 3 times the rated current, the device can withstand it without causing voltage drop.
◇Multiple protection functions for safety
With over-voltage, over-current, over-temperature, short-circuit protection and alarm devices. In case of abnormal situation, the electronic circuit of this machine will automatically detect and immediately protect it, and at the same time, it will send an alarm to notify the user to deal with the emergency situation.
