Description
PRODUCT OVERVIEW
ABB 1MRK002239-BBR01 is an original plug-in switching power supply board exclusively matched with ABB Relion 650 and 670 series protection & control intelligent electronic devices (IED). It converts substation AC/DC auxiliary power into multiple groups of isolated stabilized DC power for the relay’s main CPU, sampling circuit, communication chip and digital I/O loop. Adopting passive heat dissipation design with built-in lightning surge, overvoltage, overcurrent and short-circuit protection circuits, it features low output ripple, high isolation strength and strong anti-electromagnetic interference capability, adapting to harsh working conditions of high voltage substations and power plants. Widely used for failure replacement and emergency spare backup of feeder protection, transformer protection, generator protection and busbar protection relays in power grid transmission & distribution systems.

COMMERCIAL PROCUREMENT PROTOCOL
- System Compatibility Audit: Professional power automation engineers verify the corresponding protection device model, rack slot specification and hardware version to realize zero-modification seamless replacement.
- Graded volume discount mechanism: Optimized unit price matching different purchase quantities, synchronously update real-time inventory data and international logistics expense information.
- Full-set export document service: Provide standardized complete export materials and unified HS declaration plan to improve customs clearance efficiency for global power industry customers.
- Issuance of stamped official commercial PI: Cooperate with internal financial approval and capital payment workflow of power enterprises through formal stamped proforma invoice.
- Standard cross-border settlement mode: Support mainstream international payment represented by T/T telegraphic transfer.
- Comprehensive pre-delivery performance verification: Each power board undergoes continuous load aging test, each channel output precision calibration, ripple noise detection and protection function triggering test before warehouse delivery.
- Standard anti-damage export packaging scheme: Vacuum ESD sealed bag + customized high-density shockproof foam + pressure-resistant thickened export carton, effectively preventing power device desoldering and PCB damage caused by collision and extrusion during cross-border long-distance transportation.
- Authorized global logistics distribution: Cooperate with official operation channels of DHL, FedEx and UPS, and feed back real-time tracking number immediately after goods are delivered to logistics providers.

FAQ
What core role does 1MRK002239-BBR01 undertake in substation protection relays?It is the core power source of the whole protection IED. Stable multi-channel power supply ensures reliable operation of fault sampling, logic judgment and trip output functions of the protection relay, avoiding protection refusal or misoperation caused by power supply abnormality.Will replacing this power board clear the original relay setting parameters?Protection fixed values and configuration data are stored in the relay mainboard flash memory; power board replacement will not erase any program parameters, only power-on reset detection is needed after installation.Are second-hand disassembled power boards fully inspected before delivery?All recycled used boards go through circuit cleaning, capacitor aging screening, full-range output calibration and long-time power aging test strictly on professional test benches to restore factory performance indicators before delivery.Delivery cycle for spot goods?Goods are stored in domestic warehouse, all delivery formalities will be finished within 3 working days after payment confirmation.
