1.5.10 OPS3 3 PH VOLTAGE AND CURRENT SAMPLE BOARD
This board accepts IGBT rectifier input voltage and current samples and sends to the main controller board
for measurement purposes.
A)
Basic Functions of OPS3 Board
1.
IGBT rectifier AC input voltages (phase-neutral) are connected to CN1. These voltages are
stepped down to a suitable level by the transformers T1, T2, T3 and then sent to the main controller
board P3MC-R5 through CN7 of the OPS3 board.
CN1-1 : Neutral
CN1-3 : Rectifier input R-phase (220-230V AC to T3 through the fuse F3)
CN1-5 : ‘’ ‘’ S-phase ( ‘’ T2 ‘’ F2)
CN1-7 : ‘’ ‘’ T-phase ( ‘’ T1 ‘’ F1)
2.
The outputs of the rectifier input current transformers are connected to CN2, CN3 and CN5. The
current samples are sent to the main controller board P3MC-R5 again through CN7 of OPS3 board.
CN2 : R-phase input current sample
CN3 : S-phase ‘’ ‘’ ‘’
CN5 : T-phase ‘’ ‘’ ‘’
3.
It takes the low voltage bypass samples from ADVS01 board through its CN8 socket and generates
a fast ‘’bypass or line failure signal’’ for ECOMODE operation. This signal is sent to P3MC-R5 board
via CN7 of OPS3.
4.
HF supply signal is connected to CN4 of OPS3 board and used to p/- 12V DC supply
voltages for the operation of the board.
B)
OPS3 Board Test Points
-TP1 : Rectifier input T-phase (220-230VAC)
-TP2 : ‘’ ‘’ S-phase ‘’
-TP3 : ‘’ ‘’ R-phase ‘’
-TP4 : Neutral
-TP5 : -12V DC (+/-1.0V)
-TP6 : +12V DC (+/-0.5V)
-TP7 : VREF1
-TP8 : GND
C)
OPS3 Board ‘’jumper’’ Positions
JP1-1 = ‘’0’’ (open circuited)
JP1-2 = ‘’1’’ (short circuited)
JP3 = ‘’0’’ (normally open, shorted only for 110-120VAC output units)
D)
OPS3 Board Fuses
F1 : Rectifier input sample T-Phase (315mA)
F2 : ‘’ ‘’ ‘’ S-Phase ( ‘’ )
F3 : ‘’ ‘’ ‘’ R-Phase ( ‘’ )
