A DROP-IN REPLACEMENT TOOL FOR BOTH BATTERY AND ULTRACAPACITOR BASED SYSTEMS

LaFox, IL, September 15, 2022– Richardson Electronics, Ltd. (NASDAQ: RELL), a global provider of engineered solutions for green energy applications, announced today a new patent pending shunt resistor accessory for the ULTRA3000^® Pitch Energy Module (PEM). The designed shunt resistor is a drop-in replacement for the OEM shunt resistors used in utility scale wind turbines that utilize electric pitch systems. The shunt is used to monitor current feedback to the turbine controller during pitch events, allowing the controller to notify operators of potential electrical or mechanical issues within the pitch system. This device is crucial to turbine operation and required for full operation. Richardson Electronics’ design works with either battery or ultracapacitor equipped systems. This device will reduce failures in short-circuited pitch motor scenarios and decrease turbine down time.  Installation hardware included.

“Our new shunt resistor is just another example of how our engineers and manufacturing teams work together with our customers to deliver innovative solutions,” said Greg Peloquin, Executive Vice President of Richardson Electronics’ Power & Microwave Technologies group. “This new product design ensures less failures and reduces overall maintenance cost for the customer.”
