Output Power Curve
This curve is valid for both low-line and high-line operation. Use the table following the curve for
the current levels at key voltage levels. The rectifier can deliver constant power to approximately
48Vdc. Further loading of the rectifier will result in the rectifier operating in the constant-current
mode. If the rectifier is loaded below approximately 36V, the rectifier enters the hiccup mode.
During start-up, the rectifier can deliver an increased amount of current as specified at point C.
Point B is the nominal operating point. Point D is the internal thermal threshold beyond which the
rectifier shuts down to protect itself. Point D is not based on constant power.
Troubleshooting QS-Series Ringers
The status of a QS-Series ringer is provided by a tri-color on the face, and by alarm and event
history accessible through the system controller.
