The Mitsubishi BU-H15K is a robust brake unit designed to enhance the performance of inverters in demanding industrial applications. This unit is particularly suited for scenarios that require significant braking torque, such as when a motor is driven by a 400V class transistorised inverter, or when rapid deceleration is necessary due to the motor being rotated by a load.
Crafted with precision, the BU-H15K operates effectively within a DC line voltage of less than 800V and an operating voltage of 740V DC ± 3V. It is engineered to deliver consistent braking torque, with a standard rating of 50% for 30 seconds, ensuring reliable performance in various operational conditions.
The unit's ambient operating temperature range from -10°C to +50°C allows it to function optimally in a wide range of environmental conditions. Its approximate weight of 3.5kg makes it a manageable addition to your system without compromising on durability.
The Mitsubishi BU-H15K is finished in a Munsell 5Y 8/1 colour, which provides a professional appearance while maintaining a 50% luster that is suitable for industrial environments. Its design considerations include safety features that prevent electric shock and fire hazards, making it a safe choice for integration into your existing systems.
This brake unit is an essential component for applications that demand high-performance braking capabilities and is a testament to Mitsubishi's commitment to quality and reliability in automation technology.

Absolutely fantastic service. Rob was very helpful. Great communication. Requested part was shipped in no time.Konrad Eliaszuk
Found the component i was looking for ad a great price. Great support from the staff as I was paying using a wire transfer. - Quick delivery and very good packaging.Adriano Tiberi
Extremely Helpful. Shipped me a replacement unit next day and i was up and running within 24 hours. Replacement new from machinery manufacturers was on a 7 day lead time.Sean Conlin
Found the part we needed at the best price. Spoke to Rob to make sure the part was actually in stock, as many companies don't actually have the part available to ship. It was in stock ready and the part was checked and shipped and received within a couple of days from their German stock. Would definitely use again and recommend.Chris Sentance
