Product Description:
The PSI6300.636-L2 is a medium-frequency inverter produced by Bosch Rexroth Indramat and supplied within the PSI Frequency Inverters series. It converts high-voltage, three-phase utility power into a regulated medium-frequency output that machine controllers can use to drive specialized induction equipment or variable-speed motors in automated systems. The integrated power supply supports the inverter’s internal electronics without requiring a separate power module. A fieldbus timing interface allows the unit to coordinate frequency control with other equipment in a production line.
The electrical input range spans from 480 to 690 VAC, so the unit can be connected directly to common high-voltage plant feeders without an autotransformer. An internal phase-locked oscillator tracks mains power at 50 or 60 Hz, enabling the same unit to operate with either standard supply frequency. The control electronics are powered by a dedicated auxiliary rail that supplies 24 VDC. This rail provides up to 2 A of current for compatible sensors or contactors connected within the inverter cabinet. The housing has an IP20 protection rating, so it prevents accidental contact with internal components but does not provide complete protection against dust or water. The inverter must therefore be installed inside a suitable enclosure that protects it from conductive debris and moisture.
During operation, the inverter maintains thermal stability within an ambient temperature range of +10 to +55 °C. Storage and transportation are permitted within a temperature range of -25 to +70 °C, allowing the unit to remain in unconditioned storage areas when it is not operating. Maximum cooling losses reach 360 W, which must be considered when calculating cabinet airflow and heat dissipation. The air-cooled heat sink and cabinet ventilation remove the heat generated during operation. With a mass of 21 kg, the inverter can be mounted securely in an industrial cabinet while providing sufficient thermal mass for steady operation. The unit meets climatic category 3K3 for use under controlled industrial conditions. DeviceNet provides the timing connection used to coordinate inverter operation with the machine control network.
