DESCRIPTION The PCR-SIN15V48F00 Ring Generator offers high performance with an advanced overload protection mechanism. Each unit includes an internal crystal oscillator and supports all popular ringing frequencies of 16.7, 20, 25 and 50Hz. The PCR-SIN15V48F00 can continuously support up to 40 standard North American REN loads, providing a low THD sine wave ringing signal. The output ringing signal amplitude defaults to 86Vrms and can be externally adjusted to any value ranging between 45-100Vrms

High Load Indication The OHD output terminal provides indication of output High Load when the output power exceeds approximately 11 Watt. At High Load, the OHD terminal will provide an High 5V TTL Logic Level signal referenced to the V(-) terminal. This signal will remain at a High Level until the High Load condition is removed. This indication can be useful in order to keep the ring generator within a certain output voltage specifications by managing the output load.
