Product Description:
The PSI65C0.715-W1 is a medium-frequency inverter manufactured by Bosch Rexroth Indramat for the PSI Frequency Inverters series. It converts three-phase power into a controlled medium-frequency output that drives induction heating, hardening, and melting equipment in automated production cells. Housed in a cabinet, the unit connects to the machine controller through an Ethernet interface, allowing current and frequency to be adjusted in real time to match the required thermal profile. This connection supports responsive process control when production conditions or heating requirements change during operation.
The inverter connects to industrial mains ranging from 400 to 480 VAC, so it can operate in standard low-voltage plants without a transformer. Its water-cooled design removes heat from the switches and transformer through the heat sink, allowing the supply to draw up to 660 A during normal operation. When cooling flow is unavailable, the allowable draw is limited to 330 A to reduce internal heat buildup. Cabinet heat leakage is 100 W at idle and 850 W at full current, providing the information needed to size cabinet HVAC equipment. The inverter has an IP20 enclosure that protects against accidental finger contact with live parts, but additional protection is required in dusty or wet areas. A TriCore processor manages the control logic and provides deterministic execution of the current loops.
The exchanger and piping must dissipate 4400 W of cooling losses during full-power operation, which must be considered when selecting the chiller capacity. Maintaining a coolant flow of at least 10 L/min keeps the internal pressure drop at 0.65 bar, preserving available pump head while remaining below the 10 bar maximum circuit pressure. Coolant should enter the inverter at no more than 30 °C; higher inlet temperatures reduce the allowable primary current, which can otherwise reach 2400 A. Excessive coolant temperature can also reduce the available secondary current from its 120 kA capability, limiting performance in demanding induction applications. Proper flow and inlet temperature help control semiconductor junction temperatures while keeping heat transfer within the capacity of the connected cooling equipment.
