FEATURES

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
Overload Protection
Loads that exceed the number of REN that the unit is set to support
according to the preset output voltage, will momentarily clamp the
output sine wave, and trigger the ring generator overload protection.
This function
service to up to 40 North American REN loads.
The overload protection constantly monitors the output distortion
level, and will automatically reduce the output amplitude in order to
maintain a low distortion level of THD≤5%. The new output amplitude
will match the overload, according to the following table:
Output Short Circuit Protection
Loads that excessively exceed 40REN trigger an internal protection
that monitors the unit’s input current. When the input current
threshold is exceeded for approximately 600mSec, the protection
automatically shuts off the output. After the output has been off for 5
seconds, normal operation will automatically resume, depending on
the existing load conditions.

TYPICAL APPLICATION 1
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.
Inhibit Control
The Inhibit terminal functions to shut down the output and reduce the
unit’s current consumption to an idling level. It is operated by 5V TTL
logic levels referenced to the V(-) terminal. When this input is
disconnected or tied to a TTL low level, the output is enabled.
Negatively fed devices, where V(+) connects to the system’s GND,
and V(-) to negative 48Vdc, may require a few more components to
match voltage levels between the telecom system’s logic and the
Inhibit control. Recommended connection is illustrated on INHIBIT
CONTROL FOR NEGATIVE FED CONFIGURATION.
An internal synchronization circuitry activates a delay between the
inhibit command and shuts off the unit until the sine wave output
signal reaches the zero crossing. This assures that the output will
always turn on and shut off at zero voltage. Note that the Inhibit
control can be used to generate the ringing signal’s on/off intervals.
Inhibit control eliminates the need for additional external components
in cadence implementation.
Output Amplitude Control
The output amplitude nominal value can be adjusted in the range of
45-100Vrms and defaults to 86Vrms @ 15 North American REN load,
when the OAC terminal is left unconnected. Output amplitudes in the
range of 86-100Vrms can be set by connecting an external resistor,
