  • Channel 2 provides 2.5 A for auxiliary circuits

Security Power Supply

The Mean Well PSC-100A is a bare plate type security power supply designed for installation inside equipment. It delivers a dual output configuration suitable for emergency lighting, security monitoring and alarm systems. The unit provides 13.8V across two channels rated at 14.75A and 2.5A respectively. Total output power reaches 100.05W for continuous operation.

Sustained Load Behaviour

The supply maintains its rated 100.05W output across both channels during continuous operation rather than only in short bursts. Dual channel design allows the 14.75A primary output and 2.5A secondary output to run simultaneously within the combined power envelope. The AT type switching topology supports stable voltage regulation at 13.8V under constant loading conditions typical of security installations.

Interface Limits

The dual output interface provides fixed 13.8V rails with defined current limits of 14.75A and 2.5A per channel. Combined output cannot exceed 100.05W regardless of how load is distributed between channels. Builders needing higher voltage options, additional output channels or power beyond 100.05W must select a different supply architecture. The bare plate format also requires mechanical integration into a host enclosure.

Questions about this item

How much heat does the PSC-100A generate when running continuously at 100.05W?

The unit delivers 100.05W total across two 13.8V outputs. Typical efficiency for this class means roughly 12–22.5W becomes heat, so plan for warm airflow around the bare PCB.

What external AC wiring and enclosure must I provide for this bare PCB supply?

You must supply an AC mains cable, a protective earth connection, and a ventilated metal or fire-rated enclosure that meets local safety codes for the 100.05W PCB assembly.

Can the CH1 4.75A and CH2 2.5A outputs charge a 12V 100Ah SLA battery while powering a 13.8V alarm panel?

Yes. The combined 13.8V rails share a common return, so the 4.75A channel can float-charge the battery while the 2.5A channel runs the panel, provided total draw stays under 100.05W.
