1. Rated output power: 350 kW IGBT digital intelligent intermediate frequency power supply . DC voltage: ≥500V , DC current: ≥600A

Intermediate frequency voltage: ≥1500V; Rectified pulse count: 6 pulses; Power factor: ≥0.96

2. Rated input voltage: Three-phase 380VAC, 50Hz;

3. Resonant frequency: 10-20KHz with automatic tracking;

★4. Equipment efficiency ≥96%, power factor ≥0.96 (the ratio of transformer box output power to input power when output is ≥50% of rated power).

★5. Using reactance analysis control method, the stable and adjustable range of output current and power is as follows: the output current can be continuously and stably adjusted from 1% to 100%, and the output power can be continuously and stably adjusted from 0.2% to 100%.

6. The equipment is equipped with fault alarms—overcurrent alarm, water temperature alarm, water pressure alarm, and leakage alarm. Water temperature alarm values, water pressure alarm values, leakage alarm values, overcurrent limit values, and overcurrent protection values can be modified and set at any time on the touchscreen. These settings are pre-configured by the manufacturer according to requirements before shipment.

★ 7. Heating time: The total heating and welding time is about 6-10 minutes. The heating time and holding time can be set independently.

★ 8. Welding timed operation function: It has a countdown automatic stop function;

9. The equipment is equipped with a Chint intelligent circuit breaker, with a switch specification of 380V. It is a 1600A electric automatic energy storage intelligent circuit breaker, installed on the front of the IGBT digital intelligent intermediate frequency power supply. The IGBT brand and model are the well-known Infineon IGBT modules , and other electronic components are Schneider Electric components.

10. The temperature sensor uses a short-wave infrared temperature sensor specifically designed for copper metal from the renowned German brand (OPTRIS), featuring laser alignment; Model: OPTCT2MHSF; Temperature range: 385~1600℃; Distance coefficient: 75:1; Spectral response: 1.6μm. (German OPTTRIS)

11. Inductor: Considering the structural characteristics of the motor end ring, a single-sided bottom-plane heating inductor is used. A high-frequency, low-loss silicon steel sheet magnetic conductor is embedded in the heating element to improve heating efficiency. 0.1mm thick imported Japanese silicon steel sheets are used as the magnetic conductor.

12. Our company's equipment delivery period is 2-3 months. After the equipment is debugged and running normally, the warranty period is 12 months from the date of acceptance.
