Product parameters

Power input

Input voltage: 380-460V (-15% - +10%) 1 three-phase power supply

Input frequency: 45 -65Hz

Allowable voltage variation: voltage unbalance<3%

Instantaneous current drop: When the three-phase AC3B0-460V power supply is < AC300V, the input voltage is AC300V, and the undervoltage protection is protected after 15ms

Power output

Voltage: OVAC – Input voltage

Overload level: light load 120% 60s, 1min/10min

Efficiency (full load): ≥094

Output Frequency Accuracy: +0.1% (Digital Command-10- +45C) ; +0.1% (analog 25+10°C)

Control characteristics

Carrier frequency: 2-8 kHz

Frequency setting resolution: 0.01Hz (digital command), +0.06Hz/120Hz (analog command 1bit + unsigned)

Running command channel: operation panel given, control terminal given, communication given

Frequency given channel: operation panel given, digital/analog given, communication given, functional function given

Torque Lift: Automatic Torque Lifting; Manual torque lifting

V/F curves: User-defined V/F curves, linear V/F curves and 3 variable torque characteristic curves

Automatic Voltage Adjustment (AVR): Automatically adjusts the duty cycle of the output PWM signal according to the fluctuation of the bus voltage, thereby mitigating the fluctuation of the grid voltage

Effect of output voltage fluctuations

Instantaneous stop and non-stop processing: when the power is instantaneous, the bus voltage control is used to achieve uninterrupted operation

DC braking capacity: braking current: 00 —— 120.0% rated current

Process PID: It can be used for closed-loop control of process quantities

Common DC bus: The whole series can realize the power supply of multiple inverters sharing the DC bus

Over-current and over-voltage frequency reduction function: when the output current and bus voltage exceed the preset value, the frequency reduction operation of the inverter is implemented.

Sensor alarm function: when the temperature and liquid level sensor detection value exceeds the set protection threshold and holds for 10s, the inverter will alarm and stop

Use environment

Ambient temperature: -10-+45°C

Temperature derating use: >45°C, 19% reduction in rated output current for every 1°C increase, up to 50°C
