Ref. Function
A J12 - 17-50V DC mains power supply input
B P5 - Fine adjustment for on-board DC/DC power supply (12-16V)
C J14 - Output from the on-board DC/DC power supply, 12-16V/2A. Use for fans or your exciter.
D J15 - Automatic fan, 12V (powered through on-board DCDC). Total current for C+D = 2A max.
E J16 - Automatic fan, 17-48V (powered through ref A)
F J11, Control output. This output is used to control mains power supply voltage or drive power. Explained in
detail later in this manual.
G P1 - Control output minimum power limit. Explained in detail later in this manual.
H P2 - Control output maximum power limit. Explained in detail later in this manual.
I J13 - Install jumpers for mode B. In mode B the output gives DC control voltage, 0-5V, rising or falling
depending on J20 (ref J)
J J20 - Control output mode, either rising or falling (ON=RISING)
K J9 - Power supply temperature sensor (Tpsu) – 10K NTC termistor
L J10 - Stand-by indicator LED
M J8 - Stand-by switch
N J7 - VU meter header. Connects to VUMAX-1. Shows output power and SWR on 2 of the 4 available LED bar
graphs.
O P4 - SWR meter adjustment
P P3 - PWR meter adjustment
Q J3 - PWR meter sensitivity adjustment, install jumper
R J5 – Solder pads for external directional coupler (power/swr meter), no need to connect when you use Digiamp
(pcs lpf 5000 or 6000).
S J4 - Bias disable control voltage, either positive or negative. Make sure to check what your pallet needs!!
T Fine tuning for frequency meter accuracy
U J1 - LCD module
V Input power alarm activation threshold
Z J18 - RF input from exciter
X J17 - RF output, going to amplifier/pallet
Y J19 - Frequency meter range selection solder pads. Make sure to set the same range in the LCD module.
W J6 – Amplifier voltage, connect to pallet supply voltage (after fuse), no need to connect when you use Digiamp
(pcs lpf 5000 or 6000).
X1 J2 - Digiamp header, carries all relevant signals from PCS LPF 5000 PCS LPF 6000 filter boards (they include
current meter), greatly simplifying design and assembly.
