Nu-Calgon 3130-34 Power Supply Switching 24 VDC

The Nu-Calgon 3130-34 Power Supply Switching is used to change incoming line voltage to a regulated 24V-34V DC control voltage to be applied in low-voltage components of HVAC systems. It provides constant power to thermostats, actuators, relays, and control circuits to operate control logic over the system. It is installed in the control panel or electrical housing of air handlers, furnaces, or rooftop units, and it interacts with the system controls to facilitate sound signal distribution. It is used to offer a source to coordinate and communicate HVAC components in a residential or commercial setting.
