TEX500-LCD & TEX1000LIGHT
The PFC unit can operate on 115 VAC or 230 VAC input voltage. It features a
voltage selection block that normally does not require setting: see section 5.1.2
for a detailed description.
On
TEX500-LCD
, a conventional rectifier unit (without power factor correction)
may also be installed in place of the PFC unit.
8.1.3 Switching power supply (PSL1000/PJ1K and PSL5034)
The switching power supply incorporated in this amplifier feeds 50 VDC to the RF
power modules with 25 A maximum current for
TEX500-LCD
and 34 A maximum
for
TEX1000LIGHT
.
This module has a control input that enables output voltage reduction when needed
(for instance, in the event of RF output power reduction). Another input signal is
used to shut down the power supply (0V output voltage) when one of the following
conditions is verified:
•
Power output disabled (set to OFF) by user in FNC operation menu (menu 4,
see section 5.3.1);
•
Regulated power set to 0 Watt using the edit mode (menu 2, see section
5.3);
•
An alarm or fault condition has occurred (see section 5.4).
8.2 Interface board (SL010IN3001)
This board performs the following tasks:
•
It uses AC voltage from transformer TR1 to generate and distribute service
power supply over the panel board;
•
It controls and provides interfacing of the mains surge protection module
(SLSRGPRPJ1KM);
•
It controls and provides interfacing of the power amplifier supply module
(PSL1000/PJ1K or PSL5034);
•
It processes and provides interfacing of the control signals to/from the Bias
Board (SLBIAS1K3U-2);
•
It processes and provides interfacing of the control signals to/from the Panel
Board (SL007PC2001A or SL007PC2001B).
• It acquires and processes the input signals from the Main board
(SLMBDTEXLC05);
•
It feeds and operates the cooling fans;
•
It feeds and controls the LED indicator board.
