Compatible Aiphone Systems

Aiphone currently specifies the PS-1208UL for compatible:

• LEF Series

• TD-H/B Series

• RY-IP44

• TL-2000

• Select LEM Series configurations

Always verify the power requirements of the exact Aiphone equipment before installation.

LEF Series Applications

The PS-1208UL is commonly used to power standard LEF Series selective-call intercom systems without the BG-10C All Call/Chime Adaptor.

Compatible LEF equipment can include:

• LEF-3

• LEF-3C

• LEF-3L

• LEF-5

• LEF-5C

• LEF-10

• LEF-10C

• LEF-10S

Important LEF Power Note

For an LEF Series system using the BG-10C All Call/Chime Adaptor, Aiphone specifies the higher-capacity:

PS-1225UL – 12VDC, 2.5A Power Supply

instead of the PS-1208UL.

TD-H/B Series Applications

The PS-1208UL is also listed for compatible Aiphone TD-H/B Series handset intercom equipment.

These legacy commercial communication systems are commonly found in:

• Offices

• Warehouses

• Schools

• Industrial facilities

• Security stations

• Existing multi-station installations

Verify system size and total current requirements before selecting the power supply.

12VDC / 800mA Output

The PS-1208UL provides:

Output Voltage: 12VDC
Maximum Output Current: 800mA / 0.8A

This regulated output is designed for compatible Aiphone equipment requiring a 12VDC source.

Universal AC Input

The PS-1208UL accepts:

100–240VAC, 50/60Hz

The universal AC input allows the supply to operate from a wide range of standard AC sources while delivering regulated 12VDC output.

Screw-Terminal Connections

Low-voltage DC output is connected through screw terminals, providing a secure hardwired connection to compatible Aiphone equipment.

Always observe proper polarity and follow the wiring diagram for the connected system.

Ideal Applications

• Aiphone LEF Series systems

• TD-H/B Series systems

• TL-2000 installations

• RY-IP44 applications

• Select LEM Series installations

• Commercial intercom systems

• Office communication systems

• Schools and universities

• Healthcare facilities

• Industrial facilities

• Replacement power-supply applications

Important Ordering Information

The PS-1208UL should only be used with equipment requiring compatible 12VDC power within its 800mA output capacity.

Do not substitute the PS-1208UL for equipment requiring:

• 12VAC

• 18VDC

• 24VDC

• 48VDC

• More than 800mA

• A PS-1225UL for higher-current LEF applications

Always verify the Aiphone system model and total current requirements before ordering.
