2.5.1Power 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.

2.5.1.1Ringing 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.

Table 2-11. Ringing Generator Load Versus REN

	Load[1REN =
Output Ringing Amplitude	6930Ohms and 8
	picoFarads]
86 Vrms	4REN
75 Vrms	5REN
70 Vrms	6REN
60 Vrms	8REN
50 Vrms	10REN
45 Vrms	12REN
Short Circuit Protection Active	>>12REN

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.
