Belismart UK 500W Pure Sine Wave Inveter STI500/24-220

Pure Sine Wave Inverter

STI series is a sine wave power frequency inverter which can convert 12V or 24V DC to 220V AC 50Hz based on full digital and intelligent design. It features high reliability, high efficiency, concise outline, small volume, full protection functions, easy installation and operation. The inverter can be applied in many fields especially for solar photovoltaic power system.

Features

◆ Complete isolation-type inverter technology, noiseless sine AC voltage of output
◆ Adoption of advanced SPWM technology, pure sine wave output
◆ Dynamic current loop control technology to ensure inverter reliable operation
◆ Wide DC input voltage range
◆ Excellent EMC design
◆ Low output harmonic distortion（THD≤3%）
◆ LED indicators for input voltage range, load power range, normal output & failure state
◆ Load short-circuit, overload, under/over input voltage and over-temperature protections and alarms, inverter’s inner fault protections
◆ Fitted for many kinds of AC loads such as household appliances, electric tools and industrial devices
◆ Wide working temperature range (industrial level)
