Wake Industrial LLC is not an authorized distributor of this product.
The Bosch Rexroth Indramat PSI62C0.732-W1 is a three-phase MF inverter from the PSI Frequency Inverters series. It features a nominal mains current of 220 Amps, a maximum primary current of 1200 Amps, and a required connection cross-section of 95 mm². The inverter supports integrated temperature monitoring, an IP20 protection rating, and handles cooling water flow with a minimum of 4 liters per minute and a pressure drop of 0.6 bar.
Internal Product Review
The PSI62C0.732-W1 is a 3-phase MF inverter with IP20 protection. Integrated temperature monitoring and a 220 A mains nominal current support stable operation in demanding drive systems. A minimum cooling water flow of 4 l/min pairs well with 700 W maximum cooling loss, making the unit a strong choice for controlled industrial installations.

Product Description:
The PSI62C0.732-W1 is a 3-phase MF inverter manufactured by Bosch Rexroth Indramat and assigned to the PSI Frequency Inverters series. It is intended for industrial motor control in automated production and handling equipment. The unit converts fixed-frequency supply lines into controlled outputs for high-power motors, allowing regulated speed and coordinated process operation. This type of inverter is suited to applications that require stable motor response and consistent control during demanding machine cycles.
At full load, the inverter dissipates 210 W as cabinet heat, and its liquid-cooled section can release up to 700 W to the water circuit. A minimum flow of 4 L/min keeps the exchanger within temperature limits, while a pressure drop of 0.6 bar at that flow remains within standard pump capability. Electrical demand on the plant mains reaches 220 A nominally, and the unit tolerates -15% voltage variation on 400 V networks and +10% on 480 V networks without derating. Category 3K3 climatic classification permits operation in standard factory halls provided condensation is not allowed. The IP20 open-chassis construction requires installation inside a switch cabinet, and integrated temperature monitoring trips the drive if cooling or ambient limits are exceeded.
During transients, the DC link can draw up to 1200 A of primary current, so supply conductors must match the required connection cross-section of 95 mm². This current demand is important during short-duration operating peaks, where undersized conductors could limit performance or increase heating. Control flexibility is supported by battery-buffered RAM that stores up to 256 user sequences, allowing rapid adaptation to different machine cycles while retaining programmed operating steps. Reliable performance is permitted at installation altitudes up to 2,000 m, and the same altitude limit applies to both continuous duty and startup.
