PSI 6300.315L2
The PSI 6300.315L2 frequency inverter from Bosch Rexroth Indramat is part of the PSI Frequency Inverters series, engineered to deliver comprehensive control for industrial welding applications. This robust unit integrates a medium frequency inverter and weld timer within a single IP20-rated housing, ensuring compliance with Protection Rating: IP20 standards. It operates on an Operating Voltage: 24 VDC +20%/–15% ripple and maintains stability across an Operating Temperature: 0 to 55 °C range. The inverter weighs approximately 21 kg and employs frame terminals capable of accommodating cable cross-sections up to 50 mm² with a tightening torque of 6–8 Nm. A built-in lithium backup battery (Backup Battery: Lithium AA 3.6V, 2-year life) safeguards the RAM-based program memory against power interruptions.
Performance features of the PSI 6300.315L2 are designed for precision and flexibility. The device supports up to Programs Supported: 256 programs user-configurable welding routines, accommodating up to Electrodes Supported: 5 (Nos. 0–4) with electrode number 0 reserved for calibration, maintenance, and diagnostics. Analog pressure control options include Analog Pressure Output (Voltage): 0–10 V or Analog Pressure Output (Current): 0–20 mA or 4–20 mA (max 500 Ω), while digital feedback can be configured via a single 24 V DC input compliant with EN 61131-2 Type 3. Integration into automation architectures is facilitated by multiple fieldbus options such as Fieldbus Options: PROFIBUS-FMS, INTERBUS-PMS, Ethernet 10 Mbit/s, and an isolated V24 interface over an Serial Interface: RS232, 9-pin D-sub connector. Startup demands are modest, with a Starting Current @24 V: Approx. 2 A for 10 ms and a steady Rated Current @24 V: Approx. 1.5 A (no I/O modules), making the inverter suitable for systems with limited power reserves.
Built for demanding industrial environments, the inverter meets Climatic Category: 3K3 per EN60721-3-3 requirements and operates reliably at altitudes up to Max Altitude: 2000 m a.s.l.. Digital input thresholds are clearly defined with Digital Input Levels: Logic 1: 16–30 V @20 mA; Logic 0: –1–4 V, ensuring noise immunity and signal integrity. In the event of extended downtime, the unit’s Storage Temperature: –25 to 70 °C rating preserves component integrity and program data. Its modular design allows straightforward integration with welding guns, presses, and robotic cells, delivering precise electrode force control and high-speed switching. This combination of robust protection, versatile communication interfaces, and extensive programming capacity makes the PSI 6300.315L2 an ideal solution for modern industrial automation and welding systems.
