The PR322 series is equipped with a special power control cabinet:
1. Adopts patented multiple over-current protection, and is provided with power-on soft start, heating current limitation, freewheeling protection, automatic stop and other functions.
2. No manual voltage gear shift or meter adjustment is required for power-on and heating process.
3. Equipped with RS485 and RS232 dual-communication connections.
4. Configured with ZRJ series calibration system software, the functions of start/stop, real-time recording, parameter query setting, etc. can be achieved.
5. While protecting the safety of the equipment, the manual operation is greatly simplified.
