Product Details

1336‑151143 is dedicated auxiliary power supply PCB board for Allen‑Bradley 1336 series complete dynamic braking system,matched with 1336‑151132,1336‑151133,1336‑151135,1336‑151141,1336‑151142 braking boards. It draws power from drive internal DC‑bus,converts and outputs multiple groups of galvanic‑isolated low‑voltage DC power,providing stable working power for each braking functional PCB.

It adopts transformer isolation structure to separate braking board power domain from main control power domain,preventing power‑domain crosstalk interference from braking high‑voltage loop infecting drive main control logic. Built‑in over‑current,short‑circuit protection circuit. When over‑load or short‑circuit occurs on braking boards, this board cuts off power output and feeds power‑supply fault signal back to main control board.

Matches original installation dimension and connector definition,supports direct replacement without extra modification. Solves typical faults including whole braking assembly non‑functional,partial braking board no power,intermittent braking function loss triggered by auxiliary power instability,braking power supply short‑circuit alarm. ESD protection must be performed during disassembly and installation.

Suitable for maintenance of legacy hoist,conveyor and other equipment with frequent regenerative deceleration conditions.

Remark:Legacy EOL spare component;original production discontinued;must be used with matched full‑set dynamic braking hardware,please confirm drive braking‑loop configuration before purchase.
