VS300 Operations and Maintenance Manual Page viiiIssue 10.0 2019-01-18 VS300 Operations and Maintenance ManualDescription Issue 10.0 2019-01-18Page 1-1 Section 1: Description Refer to the functional block diagram: Block Diagram - VS300 Transmitter - see page 1-7. This section provides a high-level description of the transmitter’s key sections. The transmitter circuitry is subdivided into four basic stages: •Ac-dc power stage •Exciter/control stage - see page 1-3 •RF drive stage - see page 1-4 •RF power stage - see page 1-4 VS300 electrical schematics Some descriptions in this section refer to electrical schematics (SD-#s). These are located in Section 5 of the VS300 Troubleshooting Manual. Ac-dc power stage See also electrical schematic Figure SD-1. The ac-dc power stage converts the ac power source to a positive dc voltage (PA volts) for the transmitter's pre-amp/IPA PWB and PA PWBs. The transmitter accepts a 1-phase ac input voltage that is between 180 and 264 V ac (208 V ac nominal). The ac-dc power stage provides +48 V to operate the RF power stage’s cooling fan as well as the low level dc voltages (+15 V and +5 V) for the control/monitoring circuitry used throughout the transmitter. The ac-dc power stage consists of ac power entrance U1, circuit breaker CB1, power supply module U2, LVPS module U3, +48 V power supply module U4 and PS distribution PWB A2. VS300 Operations and Maintenance ManualDescription Page 1-2Issue 10.0 2019-01-18 Power supply module See also electrical schematic Figure SD-1. Power supply module U2 converts the ac input voltage to a regulated dc supply (PA volts) for the PA PWB in the RF power stage. The power supply module is rated for a nominal 2000 W and provides an output voltage between 7 and 53 V (typically 48 V). The module regulates the output voltage based on a PA Volts Control input from the exciter/control PWB (A1). The module has a built-in cooling fan, senses excessive temperature conditions, and applies a PS Temp alarm signal to the exciter/control PWB. The module also senses out-of-regulation on the ac input and dc output, and applies PS Ac Fail and PS Fail alarm signals to the exciter/control PWB. All three alarm conditions cause the power supply to shut itself down, thus inhibiting the transmitter's RF output. LVPS module See also electrical schematic Figure SD-1. The LVPS module (U3) converts the ac input voltage to the regulated low voltage dc supplies. The +5 V and +15 V regulated outputs of the supply are applied throughout the transmitter. +48 V power supply See also electrical schematic Figure SD-1. The +48 V power supply module (U4) converts the ac input voltage to a regulated +48 V dc supply for the pre-amp PA PWB, and the cooling fan. PS distribution PWB See also electrical schematics Figures SD-1 and SD-3. The PS distribution PWB (A2) interfaces between the dc power supplies (power supply module, +48 V supply and LVPS) and the rest of the transmitter. It distributes the power supply module output to the PA PWB and distributes the +48 V output to the pre-amp PWB and the cooling fan. Dc current samples of the PA and pre-amp power supplies are measured on the PS distribution PWB and provided to the exciter/control PWB over an SPI bus. Status and alarm outputs from the power supply module (U2), consisting of PS Present, PS Ac Fail, PS Temp and PS Fail, are applied to the PS distribution PWB and provided to the exciter/ control PWB over an SPI bus. A fan enable circuit on the PS distribution PWB controls the application of +48 V to the cooling fan. The exciter/control PWB (A1) provides a Fan Enable signal that enables or disables the fan voltage when the RF power stage is on or off, respectively.
