2.9.1.1
Features
•
The rectifier module includes a circuit, which is capable of pre-charging the transistor modules.
This circuit charges the d.c. link capacitors of the transistor modules via current limiting resistors
in the rectifier module;
•
Modules fit in the standard DELTA mounting frames; and are configured for ‘dirty air’
applications.
•
Metal oxide varistors are included to absorb surge energy from the mains. Supply impedance is
necessary for this to function correctly;
•
Protection against d.c. link short circuits is by the use of recommended semi-conductor fuses;
•
Modules carry thermostat and thermistor temperature sensing devices, which are monitored by
the MV3000e controller to provide over-temperature protection.
2.9.1.2
Interfaces
•
Signals between the controller and rectifier module are by individual wires;
•
The a.c. and d.c. power connections have stud connections and are designed for cable
connection, however maximum sizes for busbar connections to d.c. terminals are provided in this
manual.
