MVC3003-4030
This SMPS is designed to maximise the achievable system voltage by allowing a time delay on the over-voltage
trip. The Timed Overvoltage is user configurable for up to 7.5s.
The unit is fitted with another higher voltage trip circuit. If this voltage threshold is reached the drive is tripped
instantly.
If other parallel DELTA transistor modules are fitted then these require an SMPS (MVC3003-4025) where the
over-voltage trip is set above these levels.
MVC3003-4030 must be installed in DELTA position 1 only. The -4025 version is fitted in DELTA 2 – 6 positions.
MVC3003-4025
These units are to be installed in DELTA positions 2 to 6 in multi bridge DELTA systems. Their overvoltage trip
level is set to 1290V nominal, and is intended to be a back-up for the master trip circuitry in MVC3003-4020
and MVC3003-4030. The analogue volts feedback is disabled in this variant.
If the MVC3003-4025 is fitted in the controller PL2 (DELTA 1 position) the system will trip on DC Link Under-
voltage.
Configuring The Timed Overvoltage Trip Duration
MVC3003-4020 and MVC3003-4030 are both fitted with 20X4344 daughter boards. This board contains the
configuration links for the Timed Overvoltage trip duration. The table below shows the link settings and their
corresponding duration.
