This is a handy low voltage uninterruptible
power supply (UPS) which accepts 24VAC, charges a 12 volt sealed lead acid battery, and
converts to 24VAC. This is a double conversion unit, so the output is never passed straight
from the output. This means that the input and output are always isolated. The battery is not
included in the box, and can be any size that makes sense for your system. The output 24 volt
AC inverter is rated at 40 watts for use with CCTV, security, and other low voltage
installations. It basically provides an easy to use battery back-up for 24VAC.

Advantages:
 UPS
with 24VAC input and 24VAC pure sine wave output
Makes
24 VAC equipment usable in case of AC failure. 24VAC inverter can also work with solar or other
sources of 12VDC.
Useful for powered security systems, 24VAC irrigation systems and CCTV
systems..
The 24VAC voltage output is regulated, so it is independent of power drawn.
Transformers are not voltage regulated, which makes this inverter a better power source than AC
mains.
