RPS
Ring Generator Power Supply Unit
The Ringer Power Supply (RPS) provides high voltage ring generator current required
by single-line telephone station ports of the
8SLS, 16SLS, 24SLS, 4SH/S, 8SH/S, 16SH/S,
4SH/S-LL, 8SH/S-LL, 16SH/S-LL or 8SM
cards.
Tip:
The 8SA and 24SA cards do not require RPS for industry standard, single
line telephones (SLT). The ringer generator is provided by the 8/24SA card.
The RPS operates from a nominal input of –48VDC, typically supplied by an external
48VDC rectifier or stationary battery plant. Actual input may vary from -42 to -58
volts, allowing operation;
From external battery power source while the batteries are charged at an
equalized charge rate
During a power failure, until the batteries are completely discharged.
The RPS contains a low frequency oscillator and power amplifier which convert the
48VDC input power to 75, 85, or 105 volts (16, 20 or 25Hz) alternating current (AC);
for use as a ringing and message waiting signal on industry standard, single-line
telephones (SLTs); and magneto telephone station ports. The output voltage is selected
by choosing a tap on the output transformer. The output voltage is regulated and
adjustable from the front panel. Voltage monitoring circuitry checks the output of the
RPS and produces alarm signaling to the Coral system main processor in the event of
abnormality.
Each RPS is designed with the capacity to support two fully populated peripheral
shelves with average mix of port types. If extra capacity is required, an RPS may be
installed in each peripheral shelf. The RPS employs automatic switching circuitry to
share
the output between two peripheral shelves. When two RPSs are installed in
peripheral shelves wired for shared RPS operation, an operating RPS in either
peripheral shelf supplies both shelves. If both RPSs are operational, each RPS supplies
energy only to the shelf in which it is installed.Coral FlexiCom 6000 cabinets are
