DHQD series battery characteristic analog power supply

▲Dhqd-3 battery characteristic power supply

The DHQD-3 battery characteristic power supply can simulate the output characteristics of a large-capacity battery and is a power source that provides the starter with analog battery characteristics. The power supply can set parameters such as output voltage, output current, internal resistance of the power supply through the host computer or the digital panel of the machine. It has the functions of phase loss, over current, over voltage and current limit protection. The operation is convenient and simple, and the performance indicators are higher than National standards are widely used in DC starter performance testing, production, aging, durability testing and other battery characteristics simulation. Customizable maximum output current 5000A, low output ripple, analog 20AH-4000AH battery, meet the requirements of the starter motor for no-load performance, load performance, braking performance, and performance beyond the detection of power characteristics. The characteristic power supply adopts pure digital control technology, and has the characteristics of high output stability and rapid transient response. It also has remote communication optional interfaces such as RS485, CAN, Ethernet, etc., and is connected with a computer to form an intelligent monitoring system to realize the operation of the battery simulator. Real-time monitoring of status. Battery characteristics The analog power supply can be edited to set different battery types (such as the characteristics of lithium manganate and lithium iron phosphate). The battery characteristics of different conditions can be customized by directly calling the battery.
