Powering the Amplifier
For optimal operation, verify that the ac input from the feederline to the power supply is between 38 and 90 Vac (rms) with a line frequency of 50 or 60 Hz. The waveshape of the input voltage must be
The power supply provides the additional feature of a two position (LO and HI) selector that sets the startup voltage of the power supply. The startup voltage is 38 Vac for the LO position and 55 Vac for the HI position. All units are shipped with the selector set in the LO position. The LO position is used with 60 Vac systems where 38 Vac startup voltage is required. For systems operating at 90 Vac, the selector can be in the LO or HI position. Note that changing the selector does not change the upper voltage limit but affects only the startup voltage. The voltage selector should be switched only if the power supply approaches its maximum load rating.
There is no damage to the amplifier if the jumper is not changed. However, changing the jumper ensures that the dc supply does not turn on until the proper input voltage level is reached — either 38 Vac or 55 Vac. This prevents excessive loading of the system power supply during
DANGER!
Voltages up to 90 Vac are accessible. To avoid a shock hazard, confirm that the STARLINE amplifier is not powered before removing the cover or replacing the fuses.
To power the amplifier:
1Set the power supply jumper for 90 Vac operation if required by your system.
2Determine which fuses should be installed to route power to the appropriate ports.
3Verify that the power supply output voltage is +24 Vdc.
