Mitsubishi Elevator Floor Station Power Board P280704B000G01 / G02

Power board used in Mitsubishi elevator floor station and hall call systems.

Usually installed inside:

• floor indication panels
• hall call stations
• landing signal boxes
• external display assemblies

The P280704B000G01 and G02 versions are commonly seen in Mitsubishi elevator landing communication and power supply circuits.

In some office building projects in Kuwait and Romania, technicians still replace this board during landing panel maintenance because unstable power output may affect floor display or hall call response.

Common Application

This type of board is generally related to:

• floor station power supply
• hall call operation
• landing signal transmission
• indicator panel circuits

Some maintenance suppliers also classify it as:

• hall station PCB
• floor display power board
• landing communication board

depending on project configuration.

Field Maintenance Situation

In practical service work, replacement may be required when:

• floor indicators stop lighting
• hall calls respond intermittently
• landing panels lose power
• communication becomes unstable

In humid environments or older buildings, PCB aging sometimes causes unstable voltage output after long-term operation.

Service Notes

Before replacement:

• G01 / G02 version should be confirmed carefully
• connector position should match original board
• landing panel model should be checked

Some Mitsubishi systems use similar-looking boards with different communication layouts.

Usually supplied for:

• maintenance stock
• modernization projects
• old Mitsubishi elevator repair
• landing panel refurbishment
