Compatible Aiphone Systems

The PS-1225UL is specified for compatible Aiphone equipment including:

• TD-H/B Series

• LEF Series with BG-10C

• RY-IP44

• TL-2000 Series

• Select IE-8 Series applications

• Other compatible Aiphone equipment requiring 12VDC within the available power capacity

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

TD-H/B Series Power Supply

The PS-1225UL is the recommended power source for compatible Aiphone TD-H/B Series selective-call intercom systems.

This includes stations such as the:

• TD-3H/B

• TD-6H/B

• TD-12H/B

• TD-24H/B

The number of stations and accessories installed determines the overall system power requirements.

LEF Series Applications

The PS-1225UL is specified for LEF Series systems incorporating the BG-10C All Call / Chime adaptor.

For basic LEF installations without a BG-10C, Aiphone may specify a lower-capacity power supply depending on the system configuration.

Universal AC Input

The PS-1225UL accepts:

100–240VAC, 50/60Hz

This wide input range allows the power supply to provide regulated 12VDC power across a broad range of standard AC supply conditions.

12VDC / 2.5A Output

The power supply provides:

Output Voltage: 12VDC
Maximum Output Current: 2.5A

This higher output capacity makes it suitable for compatible multi-station Aiphone systems and accessories requiring more power than smaller 12VDC supplies can provide.

Installation

The PS-1225UL is designed for wall mounting in a protected indoor location.

DC output connects to compatible equipment through the designated terminals.

Always observe correct polarity and follow the wiring diagram for the specific Aiphone system.

Ideal Applications

• Commercial intercom systems

• Office buildings

• Warehouses

• Manufacturing facilities

• Schools and universities

• Healthcare facilities

• Government buildings

• Security stations

• Multi-station communication systems

• Paging and intercom systems

• Aiphone replacement power supplies

Important Ordering Information

Before ordering, verify:

• Equipment requires 12VDC

• Total system load does not exceed 2.5A

• Existing Aiphone system compatibility

• Required number of stations and accessories

• Indoor installation location

Do not substitute this power supply for equipment requiring 12VAC, 18VDC, or 24VDC.
