Technical Data
6.4. Input Power Supply Requirements
Supply Voltage 200 – 240 RMS Volts for 230 Volt rated units, + /- 10% variation allowed.
380 – 480 Volts for 400 Volt rated units, + / - 10% variation allowed.
Imbalance Maximum 3% voltage variation between phase – phase voltages allowed.
All Optidrive CoolVert units have phase imbalance monitoring. A phase imbalance of > 3% will result in the drive tripping.
Frequency 50 – 60Hz + / - 5% Variation.
