1 SITUATION DBS devices require DC voltages on the coax input or output connector and the RF signals must pass through the power inserter. SOLUTION Sonora power inserters couple regulated DC voltage on coax cables while allowing the DBS signal to pass through the inserter. DC Power originates from switching, short circuit protected transformers. RELATED CONSIDERATIONS DBS devices operate at a range of voltages and currents. Power supplies consist of a power transformer and a power inserter. DC can be inserted in one direction (HRFPI) or both directions (HRFPIB) on the coax.

2 POWER SUPPLIES 2 SINGLE LNB POWERING V Min V Min V Min 16 V Min MULTIPLE LNB POWERING LNB POWERING A stacked polarity LNB or even polarity LNB requires a minimum of 16 volts at its input. Model HRFPI20 power inserters include model HRFPI and model PS power supply. LNB current is typically less than 200 ma. Using solid copper RG-6 coax with a loop reistance of 4 ohms per 100, the maximum cable length can be calculated. (20 V - 16 V) / (4 ohms x 0.2 Amp) = 500 feet. S1 S2 4SPI S3 S4 Model 4SPI-20 power inserter can power (4) LNBs. SL5 POWERING Model SL5 LNBs employ current management to minimize the current carried per coax. (500 ma total) 18 V = 200 ma, Hz = 200 ma, = 50 ma, Hz = 50 ma. AC Power may not be available at the location of the amplifier. 95 Powering of SL5 18 Vdc, 0.2A 16 Vdc Minimum 18 Vdc, 0.2A 16 Vdc Minimum 13 Vdc, 50mA 13 Vdc, 50mA 200 ft Max 103 SL5 INPUT VDC DiSEqC OUT SEQ 5V OUTPUT VDC DiSEqC INPUT VDC AMP & LNB VDC AMP & LNB 12 to 20 VDC AMP LA281a 1 DBS AMPLIFIER L Slope Compensated 28 db Gain 175 to 2400 MHz 12 to 20 VDC AMP 24V 2A HRPIR 242B 24 Vdc 2 Amp (4) coax to SL5 Starting at 18v, the max Switch to LNB distance is 200ft. Increasing the voltage to 20 volts allows the dish to be up to 400 feet from the LNB (includes the in-line current to power the LA144a amplifiers) 100 feet RG-6 Power may be inserted on the output coax using model HRFPI to send power to the amplifier and through to the LNB.

The current draw was measured at three voltages: 29 V = 324 ma = 9.40 watts 24 V = 385 ma = 9.24 watts 20V = 460 ma = 9.20 watts Model SL5 LNBs employ current management to minimize the current carried per coax.

5 POWER SUPPLIES 5 to SL5 Communication Issue : Too many s talking to the SL5. What is the affect of combining the multiple SWM LNB power and 22 khz tones? Multiple 22 khz signals when combined can create constructive and destructive interference. 180º out of phase combining will reduce the 22 khz signal to zero! The following web location has a live demonstration on the affects. superposition/superposition.html Solution: Model HRPID1422A is a polarity locker that generates a fresh set of voltages and 22 khz tones while blocking the 22 khz signals generated by multiple switcvhes V 20 V ft 100 ft 150 ft HRvS4 HRvS4 HRvS4 HRvS V IN PHASE 22 KHZ CONSTRUCTIVE PHASE SHIFT 22 KHZ 28V, 1.5A SWITCH POWERING DESTRUCTIVE PHASE SHIFT 22 KHZ ft 100 ft 20v HRPID1422A POLARITY LOCKER º LHCP 14v º RHCP 20v 110 RHCP 14v 119º RHCP 24 PS ft 28V, 1.5A HRvS4 HRvS4 HRvS4 HRvS4
