逆变器 2KVA to 6KVA
Our modular power inverters with parallel functions is a kind of inverter device which converts 48VDC power from communication and electric data rooms into 220Vac/50Hz outputs.
Application:
Widely used for telecom,communication center,data center,IT,power substations,ect.
Introduction:
Our modular power inverters with parallel functions is a kind of inverter device which converts 48VDC power from communication and electric data rooms into 220Vac/50Hz outputs. Which is with parallel redundant design scheme, small size, convenient for parallel machines, is specifically for reliability of power supply, maintain ability, ect.
Main features: Digital Control: Using 32-bit DSP full-digital, high-frequency SPWM technology, with anti-interference ability, fast operation, high intelligence, high control accuracy, and high quality of output waveform.
N + 1 parallel redundancy design: Can be composed of N + 1 parallel redundant power system, modules for each other backup, high reliability, flexible and convenient configuration.
No master-slave parallel technology: the operation and parallel connection of each module is controlled independently by built-in DSP, no single point of failure, and autonomous current sharing between modules. With hot swappable function: no need to do any parameter setting and operation, modules automatically work into the normal working state, maintenance and replacement is simple and easy.
Modules are built-in bypass: Users can choose inverter priority or bypass priority.
Monitoring and management: Indicator panel, trouble-alarm, with RS485 communication interface and dry contact.
Protection function: It has input over-voltage, under-voltage, output over-voltage, under-voltage, over-temperature, short circuit and other protection functions.
High power density: Adopt 19-inch rack design, save space, convenient and parallel machine.
