Product Description:
The PST6100.630-L is a thyristor power unit that belongs to the PST Thyristor Power Units series produced by Bosch Rexroth Indramat. Positioned between the AC mains and industrial heating loads, it uses phase-angle control or zero-cross switching to regulate thermal output without mechanical relays. The module provides a compact solid-state interface for PLC-directed power modulation in automated furnaces, dryers, and other resistive process equipment. It is suited to applications that require repeatable electric heat control with solid-state switching.
In regular operation, the device supports a Nominal System Current of 130 A, while its Continuous Thermal Current of 110 A is the maximum current the thyristor stack can carry continuously without exceeding junction limits. A Duty Cycle of 50% suits batch processes that demand pulsed energy delivery and keeps heat generation predictable. Cooling is air cooled, so cabinet airflow must be maintained, and an onboard sensor halts firing if the heat sink overheats. Surge resilience is provided by a MOV that suppresses transient line spikes. Temperature monitoring is integrated into the control section, and connection terminals accept copper conductors up to the 50 mm² wire range. Logic functions are timed over DeviceNet, enabling synchronized gating commands with higher-level controllers.
The assembly carries an IP20 enclosure rating, so it must be installed inside a suitable cabinet that shields it from dust and water jets. The enclosure is intended for cabinet installation rather than direct exposure on the machine. Control electronics draw from a dedicated 24 V DC supply that remains active during normal operation. Reliable conduction is supported up to a maximum ambient temperature of 55 °C, provided the incoming cooling air does not exceed 45 °C and the installation site stays below the 2000 m altitude limit. With a mass of 12.5 kg, the unit can be secured to conventional DIN mounting plates without additional bracing, which helps keep cabinet layouts compact.
