The device is internally controlled by a unique micro-controller, which enables flexibility in setting both the output frequency in the range of 15 to 50Hz and output amplitude in the range of 45 to 86Vrms1. The internal controller automatically adjusts and recovers the output amplitude for overload, overtemperature, and short circuit. At power connection or start-up by the Inhibit terminal, the device turns it' output On and Off at the sine wave zero crossing, and provides an isolated zero crossing synchronization output. The PCR302 Series advanced four-quadrant power topology delivers high efficiency over the entire input voltage range of 36-72Vdc, and operates at -40°C to +85°C. Output Overvoltage Protection An independent internal protection circuitry shuts down the ring generator in the event that the output voltage tries to exceed its defined operating range. This feature allows meeting international safety standards. The ring generator automatically recovers when the output voltage returns to its safe operating range. An external Transient Voltage Suppressor device should be used for external high voltage transient protection. Automatic Overload Control Loads exceeding the maximum rated load by 1% to 20% activate the Overload Protection. While the Overload Protection is active, the ring generator automatically reduces its output amplitude and raises its output current limit in order to sustain output power of approximately 30 Watt. The ring generator gradually reduces its output amplitude from any set nominal amplitude until it reaches 45Vrms2 for an unlimited period. For handling overload that requires voltage lower than 45Vrms, the device reduces its output amplitude to 30Vrms and remains at this level for duration limited only by the thermal protection. The device will shut off for a maximum duration of 2 seconds if the output current exceeds approximately 1Arms. While the output is disabled, the Test output changes to a low logic level. After a maximum delay of 2 seconds, the ring generator automatically reverts to normal operation depending on its existing load condition. This unique procedure ensures continuous service during overload conditions. Thermal Protection An internal thermal protection automatically reduces the ring generator output power, according to an internally programmed Safe Operating Area, in the event that the internal temperature exceeds a preset threshold. The ring generator automatically reverts to full output power once the internal temperature reduces to the specified operating temperature range. 1 The PC-R302-825 offers an extended output voltage control of 5095Vrms. 2 The minimum output voltage of the PC-R302-825 is 50Vrms. PowerDsine Ltd. PowerDsine, Inc. PowerDsine Europe Input Under/Over Voltage Protection The input voltage protection circuitry shuts down the ring generator when the input voltage is under/over the defined operating range. The ring generator automatically reverts to normal operation when the input voltage returns to its defined operating range. Digital On/Off Control The Inhibit control terminal (pin 7) functions to shut down the output and reduces the device current consumption to an idling level. TTL logic levels referenced to the FGND terminal (pin 6) operate the Inhibit terminal. When this input is disconnected or tied to a TTL low level, the output is enabled. A logic high level inhibits the output and minimizes the device's current consumption to an idling level. Turn On and Off functions are executed during the output sine wave zero crossing, improving reliability. 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.

The PC-R302-825 ring generator has an extended output amplitude range of 5095Vrms. The PC-R302-543 ring generator output amplitude is set to 86Vrms. The V0 input terminal (pin 10) controls the output amplitude in digital and analog operation modes. When V0 is set to <1V in reference to the DGND terminal (pin 12), or shorted to DGND, the output amplitude is set to its default 75Vrms value. When V0 >4V or V0 is left open, the output voltage is sets to 86Vrms. When applying to V0 voltage in the range of 1.152V to 3.804V the device changes to its analog amplitude setting mode, and sets its output amplitude according to the table below. Any output voltage setting will take effect only at startup, by power connection or by Inhibit command.

The output is an open collector referenced to the FGND terminal (pin 6). This output may provide up to 30V signal level by using an external pull up voltage. This can be used to synchronize relay switching with output's zero crossing. When the ring generator shuts down as a result of shorted output, over-temperature or disconnected input voltage, this output will revert to a high level. Output Frequency Setting The PC-R302-925/926/825 ring generator supports all four popular output frequencies: 17, 20, 25 and 50Hz. The F0 (pin 8) and F1 (pin 11) input terminals select the device output frequency by TTL logic levels referenced to the DGND terminal (pin 12). Changes take effect at startup, by power connection or by Inhibit command activation. The PC-R302-543 ring generator output frequency is set to 25Hz. Output Frequency F1 F0 17Hz "0" ref. To DGND "0" ref. to DGND 20Hz "0" ref. To DGND "1" or disconnected 25Hz "1" or disconnected "1" or disconnected 50Hz "1" or disconnected "0" ref. to DGND Other output frequencies, in the range of 15Hz to 50Hz, in 1Hz resolution may be ordered. Test Output Signal The Test output terminal (pin 5), based on an independent internal circuit, provides an open collector logic high level, referenced to the FGND terminal (pin 6), to indicate proper functioning of the ring generator output. A low logic level appears at this terminal when one of the following occurs: Output Overcurrent, Over Temperature, Vin Undervoltage/Overvoltage, High Logic Level at the Inhibit Control Terminal or an Output Overvoltage. While the unit is normally operated, this output will be at high level. The Test Output Signal can be used as ‘Output Good Signal’. Ring Generator Fault Detection A Ring Generator Fault Detection indication can be achieved using the Test, the Sync and the Inhibit Outputs, as seen below:: Inhibit "1” X "0" "0" Conditions Load Input Voltage X Normal X Under/Over or Disconnected Input Voltage Normal Normal OverLoad* Normal "0" Short Normal Over-Temp., Internal Temp. >100°C *Load > 30VA = Overload Output Off Off On Lower Amplitude Off Off Status Sync "1" "1" Test "0" "0" Square Wave Square Wave "1" "1" "1" "0" "0" "1" Output DC Biasing Since the ring generator's output is isolated and floating, it can be superimposed on negative or positive DC voltage. When this DC bias option is utilized it is recommended to follow the connections described in the Typical Application 2 schematics.

When Vout=86Vrms, ZLmin =Voutmax2/Poutmax=862/30=246.5Ω in normal operation, Power Factor ≥0.5. Lower values of ZLmin are considered as overload conditions, see Automatic Overload Control paragraph for device behavior. 9. Power Factor =COS(ATAN(1/2⋅π⋅F⋅RL⋅ CL)), ZL= Resistor (RL) in series with capacitor (CL) 10.

R2 max=(Vcc(min)-VOH) / Ix, R2min= (Vcc(max)-VOL)/(IOL − Ix), IOL x VOL=13.5 mW max, Vcc max=30V, Ix=external load current tied to R2. Typical R2=10KΩ. 13. Thermal characteristics were measured assuming connections made according to Typical Application 1, and vertical mounting. 14. The PC-R302-925 is designed to meet the EN55022 class B standard requirements with an external EMI filter. 1. SAFETY INSTRUCTIONS (According to UL1950, CSA C22.2 No. 950 and EN60950 Safety Standards requirements) 1. 2. 3. 4. For North America, input voltage (nominal 48Vdc, tolerance 36-60Vdc) must be applied by isolated DC source complying with the earthed SELV or TNV requirements of the UL1950, Third edition. For other countries, input voltage (nominal 48Vdc, tolerance 36-72Vdc) must be supplied by isolated DC source complying with the earthed SELV or TNV requirements of the latest version of EN60950. DC input must be protected by UL Listed fuse rated maximum T2A, 250V (slow-blow 2A, 250V fuse). When applicable, protection from excessive voltage on the output should be tested in end-use equipment. For output voltage exceeding 80Vrms, compliance with the ringing signal requirements should be tested in end-use equipment. When output voltage is set to less than 80Vrms, ringing signal complies with M.2 requirements of IEC950.
