115 VAC power supplies in this category provide fixed 12 VDC or 24 VDC output, while some models offer selectable 12 VDC or 24 VDC output, with current capacities ranging from 1.2 A to 10 A. Protected output configurations range from a single output to two, five, eight, or sixteen individually protected outputs, depending on the power distribution requirements.

Review the installation instructions and applicable electrical requirements for the 115 VAC, 60 Hz input, including circuit protection, wiring, grounding, enclosure, and the supply’s selectable 12 VDC or 24 VDC output. For standby batteries, verify that the supply supports sealed lead-acid or gel batteries, match the battery voltage and capacity to the charger, observe polarity, and review connections for battery presence, low-battery, and AC-fail supervision.

Choose a single-output 115 VAC power supply when one device or circuit needs a dedicated 12 VDC or 24 VDC output, such as a lock, camera accessory, or other security load. Choose a multi-output or access power distribution configuration when a project powers several devices and benefits from individually protected outputs, switched fail-safe or fail-secure control, trigger inputs, or fire alarm interface options.

Battery charging keeps compatible standby batteries ready to support connected access control, security, or CCTV equipment when the 115 VAC input is interrupted, while AC failure supervision reports a loss of primary power. Short-circuit and overload protection helps limit damage to the power supply and connected circuits, with auto-resetting protection available on many outputs.
