The DBU-5C corresponds to the DBU-50 size (837.02.01) and pairs with Reliance Electric inverters to improve stopping performance for high‑inertia loads. The unit supports an optional diagnostic card (DBU-50‑DIS, 837.02.02) for built‑in fault and status monitoring. For safe operation, the braking unit must be mounted in the vertical position, and ambient operating temperature is 0–40 °C with derating of about 1.5% per °C above 40 °C up to 55 °C. Typical applications include braking and energy dissipation for large DC motors in industrial drives, conveyors, hoists, and material‑handling equipment where regenerative energy must be absorbed by a braking resistor network rather than returned to the supply.\u003c\/p\u003e\u003c\/div\u003e","brand":"RELIANCE","offers":[{"title":"New","offer_id":51708569813294,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_3861d93a-67ef-43e6-ac48-47f895da2cd7.jpg?v=1770246181","url":"https:\/\/plgautomation.com\/products\/reliance-8370201-dynamic-braking-unit-dbu-5c","provider":"PLG Automation ","version":"1.0","type":"link"}
