BWT1500 serial 48Vdc &220Vdc modular parallel connection inverter is an inversion device that converts 48V dc/220Vdc power supplied by communication DC power supply into 220V/50Hz sinusoidal AC power. Through conversion on the input DC power, the Pure Sine wave inverter offers users stable and Non-distorted AC power. In case of a power failure in business places, it offers key devices the power of flexible output voltage and frequency.
Digital control: It adopts 32-bit DSP full digital and high-frequency SPWM technology, featuring strong anti-interference ability, fast calculation speed, high intelligence, accurate control precision and pure output waveform
N+1 parallel redundant design: It can form an N+1 parallel redundant power supply system. The modules are backup each other, with high reliability and flexible configuration.Large 128*64 digital LCD display data information,4 led display working;
No master-slave parallel technology: The operation and parallel connection of each module are independently controlled by the built-in DSP, no single point of failure, independent flow between modules.
With hot plugging: no need to do any parameter setting and operation, plug and play, the module automatically enters the normal working state, maintenance and replacement is simple and fast.
Module built-in bypass: Users can choose inverter priority or bypass priority
Monitoring management: indicator panel, fault sound and light alarm, RS485 communication interface and fault dry contact.
Protection function: It has the functions of input over-voltage, output over-voltage, over-temperature, short-circuit and so on.
High power density: 1/2 19〞 width design, the volume is only half the width of the conventional inverter, saving space and convenient parallel.
