Function : VFP series variable frequency power supply equipment is specialy designed and manufactured for the harsh use environment of port wharf, floating dock, ship, offshore chiling platform, etc. k is widely used in higt-qualty frequency and voltage stablized power supply which needs to convert between 50 Hz and 60 Hz. This series of power supply adopts modular design. The intemal PCB adopts coating curing treatment, and the sine wave fitter and output transformer are impregnated in insulating paint and sprayed with high-temperature protective paint, which provides high insulation level and protection ability. The product meets the technical specification of wharf shore power facilties construction and the requirement of China Classification Society.

Features :

with remote monitoring function, real-time display of power supply running status.

Perfect protection function: With over-voltage, under voltage, over current, phase loss, over heatng protection and alarm

High reliability: With Perfect protection design, the transformer is impregnated in insulating paint and sprayed with high-temperature protective paint, and the PCB adopts three-proof process, which provide good dust and moisture resistance and durability. The improved air duct maximizes the potential of the air cocting system, and the internal heat is released quickly to ensure the long-term reiable operation of the whole machine.

Strong anti-interference ability. Using the optical fiber drive control technology, the system has strong ant electromagnetic interference abilty and reliability.

Green, efficient, energy saving: High power variable frequency power supply input can adopt high power factor active rectification. The input harmonic and power factor are close to 1, which meet the require ments of energy saving and environmental protection.

Friendly human-machine interface: With large screen LCD and LED, the man-machine interface service is convenient, and power suppy running status, parameters and alarm information are clear at a glance.

Simple structure and convenient maintenance: The modular design of internal power unit makes it easy to install, maintain and operate

Fully digital control: The system adopts the latest digital processor to implement full digital control on each power coversion unit of the power supply, which has the advantages of fast speed, high precision and higher system stability. I can make the shore power supply complete the seamless switching from ship to shore and from shore to ship.

For example: VFP-3844100
It means that the input voltage of VFP type variable frequency power supply is AC38JV. The curput voltage is AC440V, and the output capacity iS 100KVA

VFP series marine static shore power supply is divided into outdoor type and indoor type. Users can choose different capacity and different working made according to different use environment. The Indoor power supply is generally installed in the substation room or cabin near the shipyard. The outdoor type is generally: installed on the quayside and ship deck to provide power supply for ships requiting frequency conversion power supply.

Variable frequency power supply mainly consists of input and output circuit breaker, reactor, frequency conversion unit, sine filter, output transformer, etc

With local / remote start, stop and other functions.
Aam function: including input over / under votage alarm, output over / under voltage alarm, overload warning / alarm, over temperature alam, short circuit, alarm, alam can be silenced.
Protection function: including input over / under voltage protection, cutput over / under voltage protection, overload protection, over temperature protection, short circuit protection.
Display function: it can display input voltage, input current, output voltage, output current and alarm information.
I Communication function: it provides one-way CAN interface, one-way RS485 interface and one way dry contact output.
