|Question:||Specification of 12 pulse input transformer for GPD505/506- PC5/P5 series AC drive.|
The GPD505/506-PC5/P5 models of 18.5kW and higher can be equipped with 12-pulse input power supply to minimise of harmonic input distortion. To utilize 12-pulse input, a transformer with a dual star-delta secondary is required. The Specs. of the needed transformers are listed below.
The 12-pulse option can improve current distortion by 76% compared to an inverter that uses a 6-pulse input rectifier.
Rating Current and Voltage
Input Voltage and Output voltage is same
200V class ; 200~230V, ± 10%,50/60 Hz
400V class ; 380~460V, ± 10%,50/60 Hz
| Inverter Model||Current Rating (Amps)|| || Inverter Model||Current Rating (Amps)|
Ambient Temperature: 50 °C max.
Humidity: 90% RH
Dielectric Strength: 2500V ac, 1 minute
( Primary - Secondary, Primary-Earth, Secondary - Earth)
Isolation Resistance: 10 M ohm or Higher (500V DC megger)
- The secondary current includes 75% distortion current (5th and 7th harmonic).
- The secondary current values in the table above are effective values that include this distortion current.
- The primary current includes about 15% distortion current.
