u Multi-channel 24 or 28 VAC power output supplies
u Available in 4, 8 and 16 channel versions
u Wall-mountable steel enclosure
The Multi-channel Power Supplies are designed to
support multiple 24/28 VAC, 50/60 Hz camera
installations. These models operate from a 120 VAC,
50/60 Hz or from a 230 VAC, 50 Hz power source.
Housed in a steel cabinet, with knockouts included for
ease of installation and cable management, all power
supplies include channel overload protection and unit
surge protection.
Each output can be selected as 24 or 28 VAC. The
28 VAC option is ideal for applications with cameras at
the end of long cable runs where significant voltage
drops can occur. The ability to select the voltage of
each output individually provides a greatly enhanced
flexibility to meet the requirements of any installation.
These power supplies are ideal for both fixed camera
use and for PTZ camera applications.
