Product Description

15kw Explosion-proof inverter 220/380V low frequency converter Power supply


SANDI Explosion-proof inverter is the one of the most advanced technology DC to AC conversion products in the world, it’s suitable use for areas without electricity, providing a complete power solution for strict demand applications. With SVPWM technology it has high conversion efficiency, high instantaneous power and low losses power output pure sine wave, applying to capacitive, inductive and nonlinear mixed-load, with superior load capacity, perfect protection function: overload, short circuit, low/over battery voltage, improper operation etc, which won’t cause mechanical failures. This Inverter is very suitable for mining area, coal mine, gas station, solar power systems and electric power distribution system. The inverter can supply AC power to all kinds of electric equipment, air conditioners, electric motors, refrigerators, fluorescent lights, televisions, electric fans and other industrial power supply.

Explosion-proof Off Grid Inverter Application Scope:
1.Zone 1 & 2 Hazardous locations, such as: underground coal mines, wineries, chemical plants, etc.
2.Environment with IIA
IIBIIC types of explosive gas, such as: Flour mills, Aluminum powder plant, Metal mine factory, Graphite factory, etc. 
3.Indoor (IP54) or outdoor(IP65)

4. Low noise/ Silent working mode

5. Explosion proof/ Spark-proof/ Waterproof/ Anti-dust/ Shock-proof.


Explosion-proof Off Grid Inverter Features:

1.Durable4.0 thick steel plate seamless welding, surface spray, beautiful appearance.
Explosion proof rating: Explosion-proof standard is EXdIIBT4.
More reliable: Built-in low frequency isolation transformer, strong ability of anti-interference. 
4.Widespread application: DC to AC, Single phase to Three phase, High voltage to Low voltage or Low voltage to High voltage.
5.Pure sine wave output, quick instant response speed
6.Excellent performance of taking load, it can take a variety of loads, such as: halide lamps, motors, welding machines, precision machine tools, fluorescent lamps, energy-saving lamps, etc.
Powerful protection functions: With over-current, over load, under voltage, over voltage, short circuit, over heating and other protection.
High protection class: With good performance of anti-dust, waterproof, shockproof.
100% full power output: Can be 7* 24 hours continuously working

10. Accept customized: Can be customized according to customers’ requirements.
