Product description
Bel SPSPFF3-01 DC/DC Power Shelf
The Bel SPSPFF3-01 DC/DC Power Shelf delivers highly reliable Intermediate Bus Architecture (IBA) power for performance servers, routers, and network switches. It accommodates up to six hot-swap PFF3000-12-069RD DC/DC modules that convert a 40–72 VDC input (−48 VDC nominal) to a stable +12.5 VDC main output. The shelf is Open Compute Project (OCP) rack compatible and offers an optional Network Attached Controller for control and monitoring via 10/100 Mbit Ethernet, directly connected to the data center management network.
Key Features & Benefits
- Scalable: up to 6 × PFF3000-12-069RD DC/DC modules (hot-swap)
- Wide input range: 40–72 VDC (−48 VDC nominal) with two separate DC feeds
- Main output: +12.5 VDC for IBA architectures
- Management: I²C/PMBus for control, configuration, and monitoring
- Protections: over-temperature (OTP), output over-voltage (OVP), output over-current (OCP)
- OCP-ready: busbar connection for OCP V1 & V2, offset busbar design
- Optional networking: Network Attached Controller with 10/100 Mbit Ethernet
- RoHS compliant and designed for high reliability & easy serviceability
Typical Applications
- Data centers & hyperscale infrastructure
- Core/edge networking: routers, switches, gateways
- Enterprise servers & storage using IBA power
- Telecom and cloud environments

FAQ
What does OCP rack compatibility mean?
The shelf targets Open Compute Project racks and supports OCP busbar connections (V1 & V2), simplifying integration in modern high-density data centers.
How many power modules can I install?
Up to six PFF3000-12-069RD DC/DC modules. They are hot-swappable and can be replaced during operation.
Does the system support remote monitoring?
Yes. Local monitoring is available via I²C/PMBus; the optional Network Attached Controller enables monitoring and control via 10/100 Mbit Ethernet.
