Maximise the performance of your AC motors with this three-phase power module from Siemens. It's a middleman that sits between an electrical source and your equipment to manage the precision control of speed and torque. Thanks to a current rating of 90A, the unit has the muscle to meet the demands of heavy-duty applications such as air conditioners, industrial conveyors and pumps. It runs on supply voltages between 380 and 480V AC, so it handles power dips and spikes to reduce system damage and cut downtime. The built-in STO function safely disconnects torque-generated energy to prevent accidental startups.

• IP20-rated housing shields against objects larger than 12.5mm, so it's touch-proof
• Brake chopper regulates DC link voltage to prevent damage from power surges
• Screw terminals hold conductors firmly in place for uninterrupted performance

Yes, this device has internal cooling to prevent it from overheating. It works without a glitch in temperatures up to +50°C in the case of high overloads.

It's a compact module measuring just 200 (W) x 472 (H) x 237mm (D), so you can easily fit it in a crowded panel.
