ZWI series pure sine wave inverter is a dedicated power supply of a new generation of electric power and communication systems, we design and manufacture the inverter power supply according to the characteristics and requirements of the electric system, suitable for power system of power supply equipment high quality, high reliability requirements, are widely used in power system communication, carrier, monitoring, relay protection and emergency lighting. The power supply uses advanced sinusoidal pulse width modulation (SPWM) technology, the main circuit ofGermany's Siemens IGBT module drive protection forJapan's Mitsubishi thick film circuit, with the advantages of high reliability, protection and full-featured, small waveform distortion, larger power and so on.


(1) The main circuit adopts the United States INTEL microprocessor, Germany Siemens IGBT module, drive protection adopts Japan Mitsubishi movement, output partial adopts isolation transformer, safe and reliable

(2) SPWM pulse width modulation technology, the output is inverter, pure sine wave of low distortion

(3) Full-bridge circuit structure, applicable to any load

(4) DC input uses state-of-the-art anti-filling noise suppression technology, the AC input of multiple filtering to eliminate the interference of the electricity grid, communication equipment and other common DC panel without disturbing each other

(5) With a full range of power protection solutions and perfect self-detection and protection. DC input voltage is too low alarm, overload alarm, overheating alarm and short-circuit, the power will turn off the inverter output, troubleshooting, manually reset the power to work properly; Input under-voltage protection fault is cleared after the output will automatically resume

(6) Compact circuit structure, high efficiency, strong function

(7) Group-screen installation, elegant appearance


Two. Select the capacity method:

Purely resistive load power capacity= 1.1 × load power

Rectifier load power capacity= (Load current crest factor/1.5) * Load power

Pure inductive load power capacity=(Load starting current/1.5*Rated current) * Load power

Pure capacitive load= 3× load power

Mixed load: Follow the comprehensive selection of different proportion of the load
