Frequently Asked Questions
What is the primary application of the PZDW Wall-Mounted DC Screen?
The PZDW Wall-Mounted DC Screen is designed to provide stable, uninterrupted DC power for switchgear operation, protection relays, automatic devices, and emergency lighting in small-to-medium power stations, substations, and industrial distribution rooms.
What are the benefits of the wall-mounted design?
The wall-mounted structure significantly saves floor space, simplifies installation, reduces civil engineering costs, and allows for flexible placement in compact electrical rooms where traditional cabinet footprints cannot be accommodated.
What input and output electrical specifications are supported?
The system typically supports standard AC 220V or 380V single/dual power inputs, delivering regulated DC outputs (such as DC 220V, DC 110V, or DC 48V) with high voltage stabilization accuracy and low ripple coefficients.
How does the system ensure uninterrupted power during AC grid loss?
When the main AC input fails, the built-in intelligent battery management unit seamlessly shifts the load directly to the backup battery pack with zero switching time, ensuring continuous equipment operation.
Does the system support remote monitoring and communication?
Yes, it features standard RS485 communication interfaces supporting standard industrial protocols (such as Modbus/CDT), enabling remote telemetry, remote signaling, remote control, and remote adjustment.
What routine maintenance is recommended for optimal performance?
Routine maintenance includes periodic inspection of battery float charge voltages, visual checks of terminal connections for tightness, keeping ventilation pathways clean, and verifying alarm status via the central controller.
