SPATZM300 Medium Frequency Inverter Power Source


Attention:

This device is no longer manufactured. The information contained on this page is therefore not current.

The SPATZM300 1,000 Hz medium-frequency inverter power source must be used in combination with external medium-frequency transformers as a high-performance, cost-effective DC power supply within a welding current range of 2 kA to 20 kA.

Each welding operation is feedback controlled during the procedure. The control process takes place very quickly based on the 1 kHz inverter frequency. Actual values are compared with target values every 0.5 ms. The output power is adapted during the welding process if targets are not being met. Constant Current Control (CCC), Constant Power Control (CPC), Constant Voltage Control (CVC) and the adaptive MASTER mode can all be used. At the end of each weld, the SPATZM300 checks if the actual welding parameters are keeping within the limits set.

The SPATZM300's timer and medium-frequency inverter are housed in a compact IP54-protected housing, which weighs a total of 27 kg / 59.5 lb. While the external medium-frequency transformer needs to be installed close to the welding site, the SPATZM300 can be installed within the vicinity of the machine.

The SPATZBG-02 operating device is used for operating the functions and adjusting the welding parameter settings. The curve characteristics of the process signals and the measured values of the last 10,000 welds can read by the SPATZBG-02 at any time.

The SPATZM300 medium-frequency inverter is deliverable for 3~400 V-500 V mains input voltage.
