Description

PV isolation transformer IP54 250Kva outdoor for solar

Isolation transformer is used to solve the power grid problems which are caused by the photovoltaic power generation,such as harmonic, flickering, DC magnetic bias, and over voltage. Transformers are usually used between power grid and grid-connected inverter which can isolated inverter and sent the power back to grid.

Characteristic of this series:
Standard capacity: 5KVA/10KVA/15KVA/20KVA up to 200KVA stock
Rated voltage:400V/380V/220V
Connection group: YNyn0
Impedance: 3-5%
Efficiency:＞98%
Overload capacity： 15%
Electric intensity: AC3000V/min, leakage current＜5mA
Under rated power, winding temperature-rise F, less than 100K.
Meterial： High quality silicon steel sheet iron core, which achieves low no-load loss and noise. Enamelled rectangular wire for small capacity, aluminum foil for large capacity, producing with vacuum pressure impregnation which makes transformer high mechanical strength and moistureproof ability.

Advantage:
Enhanced design to dramatically reduce surge current,thus much lower chance for MCCB trip;
IP54 enclosure with build-in cooling fan, better cooling for the transformer;
LED digital display (inside) for input voltage and output voltage;
Fire-resistance terminals to reduce risk of fire;
Better cooling & better design ensure as high as 99% efficiency, make faster ROI for PV project;

Application:
Photovoltaic power generation
High Power UPS, Inverters
Lighting
Machine Tool Electrical Apparatuses
Electrical Machinery And Equipment
Medical Equipment
Rectifying Device
Wind power transmission
