HCS03.1E-F0350-A-05-NNBV

Product Description:

The HCS03.1E-F0350-A-05-NNBV from Bosch Rexroth Indramat belongs to the HCS IndraDrive Controllers line and is made to handle large power loads without choking up under pressure. It pushes out a solid 350 A continuous output current and runs on 3x AC 380...480 V with a margin of ±10% built in. The standard frequency works between 50...60 Hz, which makes it suitable for most factory mains setups. The enclosure stays rated at IP20, so it’s not built for splash zones, but inside a panel or dry control area, it stays protected.

Cooling is done using air cooling with an integrated fan, so there’s no need for external chillers or coolant lines. The weight lands somewhere between 28 to 30 kg, depending on the final setup, which is pretty standard for units of this class. The housing is compact for the power it holds, with dimensions roughly around 440 x 250 x 325 mm, but that depends on the specific mounting layout. It’s also got regenerative capability, which means extra energy doesn’t go to waste — it can push power back to the line during braking cycles.

The controller includes support for multi-encoder interfaces — handy for setups where the feedback type might vary between systems. That also helps when integrating mixed hardware across older and newer machines. The SERCOS III interface is supported, along with other common fieldbus types, so it doesn’t lock into one communication lane. An integrated mains supply is built in, trimming the need for extra hardware. Once locked in and wired up, the HCS03.1E-F0350-A-05-NNBV runs solid, holds performance under long cycles, and gives the kind of response needed in high-torque or multi-axis systems that can’t afford delays. It is designed to stay active, not sit idle.
