PSI65C0.660-W1

Product Description:

Bosch Rexroth Indramat manufactured the PSI65C0.660-W1 frequency inverter. This 3-phase MF inverter has control functionality to optimize industrial welding processes with precision and efficiency. Modular design allows for installation in switchgear cabinets and has an IP 54 protection, which prevents dust and water splashes from entering. Robust and feature-rich rich it’s a must have in harsh industrial environments. The PSI65C0.660-W1 has a clock frequency of 1 kHz to ensure stable and responsive output for high precision welding applications. The clock frequency determines the switching rate of the power electronics and affects efficiency and performance stability. Higher frequencies reduce thermal and electrical losses and increase energy efficiency and component life. The MOV overvoltage protection safeguards the system from transient voltage spikes, which can degrade electronic components over time. This is critical in industrial environments where electrical disturbances are common.

One of the inverter’s key features is its max output current of 2400 A and max secondary current of 120 kA when used with the PSG 3100 transformer. The high current capabilities allow the system to withstand heavy welding without performance degradation. The nominal system current of 660 A also supports its use in industrial applications where high power output is required. The cubicle cooling unit ensures the inverter stays cool even under continuous operation, prevents overheating, and extends the system life. Effective thermal management is achieved through water cooling, which has a flow rate of 10 l/min with a maximum allowable temperature of 30°C. This cooling method is very efficient in dissipating heat during high-current operations and ensures stable performance and no thermal stress on electrical components.

The integrated temperature monitoring system continuously monitors the operating condition and adjusts the cooling parameters if needed. This proactive monitoring prevents overheating and increases the reliability in long term industrial use. For system integration the PSI65C0.660-W1 has an I/O interface slot which supports parallel, serial, fieldbus interfaces. This flexibility allows the inverter to communicate with various industrial control systems and increase automation. The digital I/O control interface allows for precise controls, and the optical encoder feedback provides real time monitoring of motor position and speed required for welding precision. Also, the inverter is designed to withstand extreme environment, with a storage temperature range of -25°C to +70°C and humidity class F (DIN 40040) and is suitable for various industrial applications. The system’s ambient temperature of 45°C ensures stable operation in high temperature conditions.
