Display

LCD display or touch screen display

Input display

Display  input power three-phase line(phase) voltage, frequency, three-phase  line current, input voltage harmonic analysis, visual power, active  power, reactive power, power factor, active power meter, reactive power  measurement. (Display and measurement accuracy is 0.5)

Output display

Display  output power three-phase line(phase) voltage, frequency, three-phase  line current, output voltage harmonic analysis, visible power, active  power, reactive power, power factor, active power measurement, reactive  power measurement. (display and measurement accuracy 0.5)

Fault display

Show  fault alert information graphically and permanently record all running  data when a failure occurs for future analysis of the failure

Operation display

Display  information such as system state, operation prompt, fault location and  handling method to facilitate operators operation and maintenance of  equipment

Drawings Data Display

Each  set of variable frequency power supply is permanently stored the  drawings, instructions and other technical data of the variable  frequency power supply, and it is very convenient to consult

Compressive strength

Low  pressure: 2500V/AC, 1 minute, no breakdown fire phenomenon(leakage  current 10mA); High Pressure: 42 KV/AC, 1 minute, should not break  through the fire phenomenon

Cold insulation resistance

≥100MΩ

Noise

≤55dB（A）

Environment

Ambient  temperature is -5 °C to +45 °C, and the relative humidity is 0 to 95  °C,Working for 24 hours at 100% full load,the temperature in the  equipment cabin is in the range of 25 °C ± 1 °C

Protection Class

IP66 for equipment, fully sealed insulation; IP56 for Air conditioning

Cooling

Air conditioner

Elevation

<1000M

Protection

Input  power supply phase sequence, phase deficit(three-phase imbalance),  undervoltage, overvoltage, overcurrent, short circuit, DC bus  overvoltage (protection threshold can be set )

The  output power supply produces phase deficiency, undervoltage,  overvoltage, Overflow, short circuit, output voltage harmonic overvalue,  (protection threshold can be set )

Transformer  temperature, sinusoidal filter temperature, rectifier temperature, IPM  power module exceeds normal operating temperature, frequency converter  power supply trips protection. (Temperature value can be set)

When  the transformer temperature and the sinusoidal filter temperature reach  the fan starting temperature, the corresponding fan is started for  forced wind cooling. (Temperature value can be set)

Considering  the control of different power loads, when the output load capacity  reaches any setted value, the sound and light pre-alarm signal is  issued.After the overload alarm signal is issued for 1 minute, variable  frequency power supply stops to be protection(the setting can be  adjustable)
