Frequently Asked Questions
What is the core difference between the DPD-T and DPD-K series?
The DPD-T is a high-end vector type designed for constant torque/heavy-load scenarios with strong torque output and high speed regulation accuracy. The DPD-K is optimized for variable torque loads, supporting multi-segment V/F curves and soft start for superior energy savings, plus exclusive functions like pump dry-run protection.
Is the full Chinese menu user-friendly for overseas customers?
Absolutely! The operation panel supports one-click switching between Chinese and English, and the manual and software interface also offer bilingual versions. Both domestic engineers and overseas customers can easily debug and operate it.
What is the specific energy-saving effect of the DPD series?
For fans and pumps, the DPD-K series can save 20%-40% energy compared to traditional power frequency operation. For heavy-load equipment, the DPD-T series saves 5%-15% energy compared to ordinary inverters, while reducing equipment wear and extending service life.
Which industrial buses are supported? Do I need to purchase additional modules?
Modbus RTU is standard for basic communication needs. For Profibus-DP, CANopen, EtherNet/IP, etc., you can directly select the corresponding expansion module—easy to install with no complex configuration required.
Can it work normally in high-temperature or dusty environments?
The standard protection class is IP20, with an optional IP54 high-protection version for effective dust resistance. The operating temperature range is -10℃~60℃, with linear derating above 40℃, making it suitable for harsh working conditions.
Is the built-in PLC function sufficient? Do I need additional programming?
The built-in PLC supports basic logic control, sequence control, and linkage control. For most industrial scenarios, no additional programming is needed—just set parameters via the panel. For complex scenarios, programming can be done via Delta's dedicated software.
