Braun E1691 Power Supply Module – 24VDC Regulated Industrial PSU | Braun DCS Platform
Engineering Background: The Braun E1691 is a dedicated power supply module engineered for mission-critical distributed control system (DCS) architectures. Designed to deliver stable, regulated 24VDC power to field instruments, I/O modules, and communication backplanes, the E1691 addresses the demanding power integrity requirements of continuous-process industries including petrochemical, power generation, and advanced manufacturing.
Product Positioning: As a factory-original Braun component, the E1691 is the authoritative replacement and expansion PSU for Braun DCS installations. It is sourced directly from certified Braun distribution channels and verified against OEM specifications before shipment from Konmask.com. Procurement engineers specify the E1691 when system uptime, regulatory compliance, and long-term parts availability are non-negotiable.

Engineering Advantages
- OEM-Identical Replacement: Drop-in fit for existing Braun DCS racks — no re-engineering or firmware changes required.
- Wide-Range AC/DC Input: Accepts global mains voltages and DC bus inputs, simplifying multi-site deployments.
- Galvanic Isolation: Eliminates ground loops and protects sensitive I/O from mains transients.
- Multi-Layer Protection: OCP, OVP, SCP, and thermal shutdown prevent cascade failures in high-availability systems.
- Compact Form Factor: Maximizes rack density without compromising thermal headroom.
- Long Service Life: Industrial-grade components rated for continuous 24/7 operation in harsh environments.
System Architecture & Signal Flow
The E1691 accepts wide-range AC or DC input via its terminal block, passes through an EMI filter stage, and converts to an isolated, regulated 24 VDC output bus. The output feeds the Braun DCS backplane power rail, supplying processor modules, I/O cards, and communication interfaces. Onboard status LEDs provide real-time power-good indication. In redundant configurations, two E1691 units operate in load-sharing mode; if one module faults, the second assumes full load without interruption — a critical feature for SIL-rated safety loops.

Technical FAQ
Q: Is the Braun E1691 compatible with my existing DCS rack without modification?
A: Yes — the E1691 is a factory-original module designed for direct slot replacement in compatible Braun DCS backplanes. No hardware or software modification is required.
Q: Can two E1691 units operate in a redundant (1+1) configuration?
A: Yes. The E1691 supports load-sharing redundancy. In the event of a single module failure, the remaining unit sustains full system power without interruption.
Q: What is the lead time for the Braun E1691?
A: In-stock units ship within 1–3 business days. For large-volume orders, contact Konmask for confirmed lead time.
Q: Do you provide a certificate of conformity?
A: Yes. A CoC and functional test report are available upon request at no additional charge.
Q: What export documentation is included?
A: Commercial invoice, packing list, country of origin certificate, and HS code declaration are standard with every international shipment.
