We require frequency converters for our electrical testing laboratory to stabilize power sources. The specifications are:
- 3-phase system with Delta input and Wye output (4-wire configuration)
- Input/Output frequency: 50Hz
- Input voltage range: 0-440V, Output voltage range: 0-440V/220V
- Required capacities: 15KVA, 20KVA, 25KVA and 30KVA models
- Must handle inductive loads from electrical testing equipment
- Pure sine wave output with THD<3%
- Compliance with IEC standards for voltage/frequency tolerance
- Certification needed for ISO/IEC 17025 laboratory accreditation

No existing VFD installations in our system. Please provide technical specifications and certifications with quotation.

I am looking for a complete ultrasonic system suitable for use in high - temperature molten metal processing (up to around 1200?°C) for degassing and metallurgical improvement. Confirm: 1. Can the system operate near 1200?°C? 2. Maximum temperature resistance of the sonotrode and components? 3. What’s included in the full system? 4. Power output (W)? 5. Working frequency (kHz)? 6. Provide technical documentation or a warranty? Clarification: 1. Molten material reaches 1150–1200°C, system should be above the melt surface or partially immersed with proper thermal resistance and gas protection. 2. System for degassing and refinement of the melt structure. 3. Complete solution includes generator, transducer, booster, high - temperature sonotrode, mounting stand or tripod, HF cable and accessories. Advise: 1. Maximum working temperature the sonotrode can tolerate? 2. Available power options (min 1000W)? 3. Possible to have a system at 30 kHz? 4. Offer water - cooling or thermal insulation options for the convert?
