SPATZH300 High Frequency Inverter Power Source

The SPATZH300 high-frequency inverter power source with its 20,000 Hz clock frequency is the all-purpose, cost-effective alternative to all of the transistor-controlled power supplies for micro welding and small component welding. With its rapid reaction speed, the SPATZH300 displays high-performance, lasting welding capability, functioning with just as much precision at 100 A as it does at 9,000 A.

Each welding operation is feedback controlled during the procedure. The control process takes place very quickly based on the 20 kHz inverter frequency. Actual values are compared with target values every 0.025 ms. The output power is adapted during the welding process if targets are not being met. Constant Current Control (CCC), Constant Power Control (CPC) and Constant Voltage Control (CVC) can all be used. At the end of each weld, the SPATZH300 checks if the actual welding parameters are keeping within the limits set.

The SPATZH300's timer and high-frequency inverter are housed in a compact IP54-protected housing, which weighs a total of 27,5 kg / 60.6 lb. While the external high-frequency transformer needs to be installed close to the welding site, the SPATZH300 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 be read by the SPATZBG-02 at any time.

The specific advantages of the SPATZH300 high-frequency inverter, such as its low weight and high output voltage, allow the easy system integration. The high output voltage enables relatively long welding power lines to lead to the welding position.

The SPATZH300 high-frequency inverter is deliverable for a mains input voltage range from 3~400 V to 500 V.
