Haydon HAY-PSUMULTI10A

The total number of outputs can support up to 16 devices, but you'll need to ensure that the total power consumption of all devices doesn't exceed the maximum output power of the PSU. 

For example, if each device requires 0.5 Amps at 12VDC, you could connect to 20 devices in total (10 Amps / 0.5 Amps per device).

It's important to ensure that the voltage output is stable and doesn't fluctuate beyond the acceptable range for your devices. Additionally, you should check that the PSU has adequate protection mechanisms, such as over-current, over-voltage, and short-circuit protection, to prevent damage to your devices in case of power fluctuations or electrical faults.

Overall, a 10 Amp 12VDC PSU with 16 outputs can be a useful and versatile option for powering multiple devices in a variety of applications, including home automation, security systems, and industrial automation.
