Specification :

As the rapid development of our power industry and broad investment for technology retrofit, the demand for DC power supply equipment and system is growing higher and higher. The JZ series intelligent high-frequency switching DC supply is featured by precisely voltage and current stabilization control, quick response, low noise and high efficiency. What’ s more, four-remote-control and N+ 1 redundant backup function can be easily obtained to make the whole system more reliable. The kernel part of this type product is JZ-xxx high-frequency power module and JZ-MC-xxx intelligent monitoring device. The capacity design of our product can be adjusted per customer’ s different demand to meet special needs.

High-frequency power supply module, intellectual monitoring module, intellectual earthing patrolling module and intellectual battery patrolling module used in JZE GZDW products are developed by JZE itself and have technical patterns. GZDW systems feature reasonable design structure, superior performance and reliable stability. They have been applied to power plants and substations of power, communication, petroleum, chemistry, electric railway, coal industries.
’ Two-channel AC input module can switch either manually or automatically. Also these two channels of AC power input can take master-slave mode ( optional) .
’ Wide range for input voltage level. Highest available voltage is 45 6V.
’ The system integrated AC power distribution, DC power distribution, high-frequency power supply module, intelligent grounding patrol detection module, intelligent battery patrol detection module and intelligent monitoring module.
’ Intelligent charge management: automatically switch among main charge, even charge and float charge. Temperature compensation is also obtainable.
’ Use self-developed, self-manufactured soft switch supply modules, ( N+ 1) backup function improves system reliability greatly.
’ High efficiency, greater than 96 percent efficiency under either air-cooled or self-cooled mode.
’ Intelligent modules management can decide the on/ off state for each module. Modules work on shift prolongs lifecycle.
’ Regenerative invert sends energy back to power grid instead of wasting away.
’ Safety guarantee; third-level lightening protection and high grade insulation measures. Insulation monitoring instrument protects system and human by monitoring ground short condition online.
