High-power shore power supply for wharf power supply

Shore power supply is specially designed and manufactured for high temperature, high humidity, high corrosion, high load impact and so on, which is specially designed and manufactured with high power frequency conversion power supply. All PCB circuit boards are cured by coating; Sinusoidal Filter and output transformer are treated with whole vacuum impregnating insulating varnish and high temperature protective paint. It has high insulation level and protective ability; it is fully in conformity with the marine product certification standard of China Classification Society CCS. It is widely used in ship, shipbuilding and repair plant, ocean drilling platform, shore wharf and so on. The power supply of 60Hz high quality frequency stable voltage and steady voltage power supply from 50Hz industry is needed, and the power supply for electrical equipment of ships can provide different voltage, frequency, and so on.

1. Input

Voltage range: 400V + 30%, (TN-S system), extreme voltage input range 400V + 50% (duration 10S).

Frequency: 40Hz~70Hz

Capacity: 5-3000kVA

2. Output

Voltage: 200V/220V/380V/400V/440V/460V/690V

Frequency: 50Hz/60Hz/400HZ

Voltage stability: < + 0.5-5%

Three-phase voltage balance mode: automatic balance

Output mode: first stabilizer output

Normal overload capacity: 1.1 times long overload, 1.5 times 1 minutes overload.

3. Protection

Overvoltage protection: output phase voltage exceeds 10%, cut off output or continuously turn to bypass (user can set).

Under voltage protection: output phase voltage below 10%, cut off output or continuous bypass bypass (user can set).

Lack of phase protection: automatic cut off overload protection: overload protection function.

Over current protection: over current protection function

Short circuit protection: short circuit protection

Bypass: an uninterrupted bypass protection function with a maintenance bypass switch.

4. Instructions
