Mitsubishi Elevator Emergency Lighting Power Board P341702B000G01 is used in Mitsubishi elevator emergency lighting power applications.

This PCB board is usually related to elevator LED emergency lighting, cabin emergency illumination, or low-voltage lighting backup circuits. In the elevator spare parts market, it may also be described as:

• Emergency Lighting Power Board
• LED Emergency Lighting Power Board
• Emergency Light Power PCB
• Mitsubishi Elevator Emergency Lighting PCB
• Elevator Emergency Power Supply Board

For this product, the exact printed part number P341702B000G01 should be the main confirmation point. Public listings consistently describe P341702B000G01 as a Mitsubishi elevator PCB emergency lighting power board.

Model Reference

The confirmed model reference for this product is:

• P341702B000G01

At present, I did not find reliable public evidence for stable G02 / G03 variants of this same board. So this page should focus on the exact model number instead of adding uncertain related models.

Customers may search this product as:

• Mitsubishi Elevator Emergency Lighting Power Board P341702B000G01
• Mitsubishi Elevator LED Emergency Lighting Power Board P341702B000G01
• Mitsubishi Elevator Power Board P341702B000G01

Where This Board Is Usually Checked

This board is usually checked when the elevator emergency light or LED backup lighting does not work normally.

Maintenance teams may inspect P341702B000G01 when there are symptoms such as:

• emergency light not turning on
• cabin emergency lighting failure
• LED emergency light flickering
• backup lighting circuit abnormality
• visible PCB damage
• no output to emergency lighting circuit

These symptoms may also be related to wiring, battery condition, connectors, or the emergency lighting unit itself. Therefore, technicians usually check the complete emergency lighting circuit before confirming the PCB fault.

Why Exact Board Matching Matters

Emergency lighting is a safety-related elevator function.

P341702B000G01 should not be selected only by appearance. Similar Mitsubishi PCB boards may have similar size or connector layout but different circuit functions.

Before ordering, please confirm:

• complete PCB model: P341702B000G01
• connector quantity and position
• installation position
• emergency lighting circuit wiring
• original board front and back photos
• any visible LED or emergency light unit connection
• original fault description

A clear photo of the board label is usually the fastest way to confirm the correct replacement.

Replacement Reminder

Before installing a replacement emergency lighting power board, technicians should check the surrounding circuit carefully.

Important checks include:

• emergency light unit condition
• wiring terminal condition
• connector oxidation
• backup battery or power source condition if applicable
• cabinet or COP power input
• signs of short circuit or overheating

If the old board failed because of an external wiring short circuit or damaged lighting unit, replacing only the PCB may not solve the problem.

For overseas buyers, please provide clear photos of the original P341702B000G01 board and the connected emergency lighting circuit before ordering.
