Up to 3× Overload Capacity
The overload capacity can reach up to 3×, significantly reducing the required power capacity for motor loads and lowering overall system costs.
Soft-Start Function
The starting voltage, frequency, and time can be configured to gradually ramp up the output voltage and frequency, effectively reducing inrush current during motor startup.
Soft-Start Output Mode
Programming – Step Mode
Up to 50 sets of output voltage, output frequency, and operating time can be configured, with up to 60,000 cycles supported. In-page looping is also available, providing flexible programmable variable-frequency power supply operation.
Step Output Mode
Step Programming Interface
Programming – Ramp Mode
The standard ramp function supports up to 100 sets of initial voltage, final voltage, initial frequency, final frequency, and ramp time. Up to 60,000 cycles can be configured for automated testing and programmable variable-frequency output.
Ramp Output Mode
Ramp Programming Interface
Programming – Stair-Step Mode
In Stair-Step Mode, users can configure the initial voltage, initial frequency, number of steps, voltage step (+/−), frequency step (+/−), and step time for flexible output control.
Stair-Step Output Mode
Stair-Step Programming Interface
Automatic Cable Voltage-Drop Compensation
The power supply automatically compensates for voltage drops in the output cables. By setting the cable impedance, the system automatically adjusts the output voltage to keep the voltage at the load closer to the set value.
Automatic Fan Speed Control
Two- or three-stage temperature-based fan control automatically adjusts the cooling fan speed according to no-load, light-load, and heavy-load conditions. This helps maintain low noise during light-load operation while providing sufficient cooling capacity under heavy loads.
7-Inch True-Color Touchscreen
The high-resolution 7-inch true-color touchscreen provides an intuitive interface and displays key parameters simultaneously, including set voltage, set frequency, output voltage, output frequency, output current, active power, reactive power, and power factor. Detailed alarm information is also displayed for easier monitoring, troubleshooting, and maintenance.
Remote Communication
The standard RS232 interface supports remote operation via PC, unattended operation, and integration into automated test systems. Optional RS485 and LAN interfaces are also available. Through the communication interface, users can start or stop the power supply, configure operating parameters, and monitor real-time operating status, parameters, and alarm information.
