Wisman High Voltage Power Supply Company is a supplier of power supply equipment for the telecommunications industry, power supply for coastline observation network, remote power supply for submarine cables of seabed observation network, shore-based power supply, marine power supply, marine power supply, and marine remote power supply supplier. A new generation of high-voltage power supply equipment (PFEA) has been developed. The new PFEA addresses the emerging requirements of short-distance submarine cable installations, while also addressing issues such as lower cost, smaller footprint, and easier operation.
The inverter can be sold separately, and the order for a single power supply for ocean remote power supply is separately accepted.
Provide (1 + 1) redundancy for the inverter
Simplified sliding drawer for PFE open circuit, ground, test mode
Provide redundancy for MCU. If the MCU fails, the PFE will continue to operate normally
MCU includes a 17-inch LCD screen, keyboard, mouse ball and CPU
Simplified key lock scheme ensures the safety of operators
Each inverter has a display (LED) to display voltage, current and working mode
The unique protective "trapdoor" barrier allows the converter or test load to be safely replaced while the PFE is still supplying power to the cable
The output voltage:
Maximum rated continuous operation 6kV, nominal value 5kV
1.2A maximum rated continuous operation, nominal value 1.0A
5kW for 1+1 redundancy
-40.5 VDC to -60 VDC
Provide full-featured programming, monitoring, alarm, diagnosis and ramp functions through the MCU module.
Fully local and remote monitoring via Ethernet connection
Current ripple: Maximum output peak is 10mA peak
Voltage ripple: Maximum output peak value is 0.2%
After 4 hours of preheating, 0.1% (constant load)
