dsPICDEM? MC1L 3-Phase Low Voltage Power Module
? Fit the resistor to the heat sink and solder the wires into J7 and J8. Ensure the
leads are cropped so that the maximum length of lead protruding below the PCB
is 4 mm.
? Once the modification is complete, install the lid ensuring all the screws are
replaced.
Note that if the user fits a lower value of internal resistor to allow higher transient
dissipation, then the user's software must ensure adequate thermal protection for the
resistor. Failure to do so can cause the resistor to rupture. Consult the manufacturers
data sheet carefully.
1.6.3.3
BYPASSING THE REVERSE VOLTAGE PROTECTION
The reverse voltage protection MOSFET dissipates an appreciable amount of power.
If the user is satisfied that this is not required, they can easily remove it by using the
following procedure. Alternatively, the user can use the auxiliary DC input on the 7-pin
output connector but this also bypasses the DC input current transducer and its
associated trip protection.
? Follow the procedure given in Section 1.6.2 “Accessing The System” for
accessing the unit.
? To remove the reverse voltage protection MOSFET Q9, undo the clip mounting
the device and de-solder it from the top of the PCB. Solder a wire link between
pads 2 and 3 of a suitable rating having cropped the leads, ensuring that the
maximum length of lead protruding below the PCB is 4 mm.
? Once the modification is complete, install the lid ensuring all the screws are
replaced.
1.6.3.4
ACCESSING THE ADDITIONAL (NON-ISOLATED) FEEDBACK SIGNALS
All the non-isolated feedback signals are brought to a series of links that run along the
edge of the isolation barrier. In order to access these signals, the user should rigidly
carry out the procedure given below. Failure to do so could represent a safety hazard
to the user.
? Follow the procedure given in Section 1.6.2 “Accessing The System” for
accessing the unit.
? Disconnect the input wiring from the DC supply outlet.
? Ensure that the earth (ground) continuity is maintained to the unit.
? In order to make the links for the non-isolated signals, it is recommended that two
0.3" pitch, 14-pin DIL resistor packages are used. These should be of the
"straight-through" type with 7 independent resistors. The suggested value is
330 ? , as this will provide some ESD protection without too high a source
impedance being introduced. Note that LK28 has no circuit connections and is
provided to allow the second DIL resistor package to be installed. If the user
decides to fit links or individual resistors, these should be installed so that not
more than 4 mm of lead protrudes beneath the PCB.
? Note that all signals to and from the system are now referenced to the -DC bus
that is at earth (ground) potential. The Digital 0V of the control card is permanently
connected to the enclosure chassis and is therefore also referenced to ground.
? Once the modification is complete, install the lid ensuring all the screws are
replaced.
