Product Description:
Bosch offers a unique temperature measurement solution named PSI63C0.333-W2 which functions as a dependable Frequency Inverter for thermocouple temperature detection. Bosch stands out through its innovative approach to developing reliable industrial automation solutions.
The frequency inverter PSI63C0.333-W2 serves applications that demand cooling features in their systems. It functions between 500 V to 690 V line voltage while accepting +/- 15% variations from 500 V mains voltage and +10% from 690 V mains voltage. Continuous thermal loads operate at stable conditions through the inverter's 110 A mains nominal current capacity. At 1 kHz frequency its transformer receives power from its primary voltage which is defined by multiplying line voltage with √2 for power conversion efficiency. This PSI series inverter’s transformer receives its maximum primary current output requirement at 800 A. System efficiency requires special attention because the basic losses of the switch cabinet reach 100 W. The unit demands at least 4 liters per minute water flow to reach proper operating temperatures while operating at its normal pressure drop of 0.1 bar under these conditions. The cooling arrangement serves to dissipate heat effectively while guaranteeing system reliability by stopping thermal overload.
The frequency inverter PSI63C0.333-W2 has mechanical characteristics and weighs only 25 kg by making it easy to install. Frame connectors that support a maximum conductor cross-section of 50 mm² are used to facilitate electrical connections by guaranteeing safe power transfer. To ensure dependable electrical contact and avoid damage from overtightening, the necessary tightening torque for these connections is specified within the 6–8 Nm range. All of these features together make the inverter a high-performing unit designed primarily for demanding industrial applications.
