SPECIFICATION
2.1
INTRODUCTION
The specifications provided in this section are for the individual DELTA components. These components are the
transistor and rectifier modules, the MV3000e Controller, the Switched Mode Power Supply (SMPS), the User
I/O Termination Panel, the Mains Voltage Monitor (MVM) – if required, associated reactors and transformers
and the installation accessories (for use in enclosures). Consideration should be given to the rating of
individual components when they are included in a CDM as derating for parallel applications may apply.
2.2
DELTA COMPONENTS (GENERAL ENVIRONMENT)
All DELTA components are designed to comply with the common specifications in Table 2–1 to Table 2–7 unless
otherwise detailed in the individual component specification. Drive performance data for an MV3000e based
DELTA drive is included in Table 2–9.
2.2.1
Electrical Supply
DELTA modules are intended to be used in a drive connected to an electrical supply with the following
characteristics:
FUNCTION
SPECIFICATION
Electrical Supply
Network Type
TN or TT (i.e. earthed/grounded neutral).
Can also be connected to IT network (i.e. isolated or high impedance neutral) if IT network
separated from public mains supply by an isolating transformer.
See Section 4.5.1: Protection Against Transients.
Voltage Range
Product dependant.
Refer to module details, see below:
MVR Phase Voltage
Section 2.9.1.6
GDR Phase Voltage
Section 2.9.2.6
MVD Phase Voltage
Section 2.10.5
MVD D.C. Link Voltages
Section 2.10.6
Voltage Variation
(on voltage range)
±
10% long term,
±
15% for 0.5 to 30 cycles with loss of performance but no trip
Voltage Unbalance
Negative sequence voltage not to exceed 3%
Frequency (optimised)
50 Hz, 60 Hz
Operational Frequency
Range
45 Hz to 63 Hz. With frequencies outside the optimised values, extra d.c. link ripple may
be apparent and may impair motor control performance.
Insulation Coordination
Overvoltage Category
(line to earth)
EN 50178, IEC 61800-5-1, UL 840, CSA C22.2 No. 0.2
TN or TT network : Overvoltage Category III
IT network
: Overvoltage Category II
For full compliance with UL 508C, transient suppressers complying with UL 1449 must be
fitted between line and earth. These must be fitted as close as possible to the point
where the electrical supply enters the drive enclosure.
