12 Technical Data
12.1 Drive technical data
12.1.1 Power and current ratings
The power ratings for the 480V configuration is shown in Table 12-1 .
The continuous current ratings given are for a maximum ambient
temperature of 40°C and an altitude of 1000m. For operation at higher
temperatures and altitudes de-rating is required.
The maximum continuous output current rating of the drive should be
‘de-rated’ for operation at altitudes above 1000m. The de-rating is to be
1% de-rating of rated output current per 100m above 1000m to a
maximum de-rating of 20% at 3000m.
Table 12-1 480V current ratings
12.1.2 Power dissipation
The table below shows the maximum drive losses, assuming high output
current ripple content.
Table 12-2 Drive losses
12.1.3 AC Supply requirements
The standard drive is rated for a nominal supply voltage up to 480 Vrms.
12.1.4 Supply types
Drives rated for supply voltage up to 480V are suitable for use with any
supply type, i.e. TN-S, TN-C-S, TT, IT, with grounding at any potential,
i.e. neutral, centre or corner ("grounded-delta").

12.1.7 Line reactors
The Quantum MP, in common with all naturally commutated SCR drives,
causes voltage notches at the input supply terminals. In order to avoid
disturbance to other equipment using the same supply, the addition of
external line inductance is strongly recommended in order to restrict the
depth of the notches imposed on the shared supply. This is generally not
necessary where a dedicated transformer is used to supply the drive.
The following recommendations for added line inductance, have been
calculated based on the power drive systems standard: EN61800-
3:2004 “Adjustable speed electrical power drive systems – Part 3: EMC
requirements and specific test methods”.

1.
The above assumes the supply has 1.5% impedance.

Assumes a minimum supply rating of 5kA and a maximum rating of
60kA.
12.1.8 Temperature, humidity and cooling method
Ambient temperature operating range:
0°C to 55°C (32°F to 131°F).
Output current derating must be applied at ambient temperatures
>40°C (104°F).
Minimum temperature at power-up:
The drive will power up at -15°C (5°F)
Cooling method:
QMP45A4(R) = Natural convection.
QMP75A4(R) upwards = Forced cooling.
Maximum humidity:
The Quantum MP Product range can operate in environments up to
90% relative humidity at 50°C.
