Mitsubishi Elevator Floor Station Power Board P280702B000G01 / G02

P280702B000G01 and G02 are commonly used in Mitsubishi elevator landing communication systems.

Normally found inside:

• hall indicator boxes
• floor station panels
• landing call systems
• external display circuits

Different from some larger landing power boards, this model is more frequently associated with signal supply and panel communication support in Mitsubishi elevator floor stations.

In several old apartment projects in Serbia and Peru, maintenance companies still keep this PCB in stock because some Mitsubishi landing systems continue using the original communication structure after modernization.

Typical Field Problem

When this board becomes unstable, common situations may include:

• floor display flickering
• landing call response delay
• intermittent indicator power loss
• unstable hall lantern operation

In some cases, technicians first inspect the external wiring and communication terminals before replacing the PCB itself.

Replacement Market Situation

This model is often requested for:

• old Mitsubishi elevator repair
• landing panel refurbishment
• hall station troubleshooting
• maintenance stock supply

Some customers purchase together with:

• hall buttons
• indicator boards
• display modules
• communication cables

depending on the condition of the complete landing panel.

Service Attention

Before installation:

• board number should match carefully
• G01 and G02 versions should be checked
• connector direction must correspond to original layout

Some Mitsubishi floor station boards use similar housings but different circuit structures.

In a few modernization projects in Southeast Asia, technicians also replace related power terminals together during maintenance work.
