2.5.1
Power Supply and Ringing Generator
The power supply and ringing generator system can consist of up to two power supplies, and
has one on-board ringing generator. The IMACS-200 comes with the proper power supplies
factory-assembled depending on the ordering information provided at the time of purchase.
2.5.1.1
Ringing Generator
The Ringing Generator on the IMACS-200 outputs 86Vrms at 20Hz. That is the output if
ringing into a 1 to 4 REN load. If the load increases, the built-in overload protection will
reduce the output voltage in steps as shown in Table 2-11.
This ability inherent in the IMACS-200 provides continuous service up to 12 North American
REN loads without distortion.
Following is more detailed information regarding the power inputs.
