Wiring Diagram
Application
Several damper actuators can be used either with 24 VAC or
24 VDC.
In case of a power failure, the NSV24 battery back-up unit
switches the damper actuator from its main AC power supply
over to the 24 VDC battery to drive the actuators to their
safety position.
For easy maintenance, the battery back-up system is placed
in the control panel, not in the actuator.
Several actuators may be powered by one back-up module.
The batteries are separate from the
NSV24.
Operation
The NSV24 is connected to the same 24 VAC power source
as the damper actuators. It also charges the 24 V (2-12 volt
batteries) storage battery. Its charge current is limited to
150 mA maximum, and the maximum charge voltage is
temperature compensated.
In case of a power failure, the NSV24 switches immediately
over to the battery power source, and according to the control
function, the actuators will move to their safety position.
After 250 seconds, the batteries are disconnected from the
actuators to prolong battery life. Because of this, a safe
battery back-up can be provided for several short-term f
ailures. The main power source operation is indicated by a
green LED, and the battery power source by a red LED.
