SCHROFF MPS022- Sturdy design, 6U height, easy to integrate into a 19 inch standard rack

Description

The SCHROFF MPS022 is a modular power supply system engineered for high-availability industrial computing and embedded applications requiring fault-tolerant power distribution. Designed as part of Schroff’s robust power solutions portfolio, this unit integrates hot-swappable AC/DC power modules with intelligent load management to deliver up to 960W of continuous power with N+1 redundancy. Its core innovation lies in distributed current sharing technology, which dynamically balances loads across modules while maintaining voltage regulation within ±1% under transient conditions. The SCHROFF MPS022 features wide-range input (85–264VAC/120–300VDC) with active power factor correction (>0.99), ensuring compliance with global energy standards like EN 61000-3-2. Designed for 19″ subrack installations, it operates flawlessly in temperatures from -40°C to +70°C with IP20 protection, making it ideal for harsh environments like rolling stock, power plants, or outdoor telecom cabinets. With PMBus 1.3 compatibility and CANopen interfaces, the SCHROFF MPS022 enables real-time monitoring of efficiency, temperature, and predictive failure alerts through integrated digital control.

Technical Specifications

Main Features and Advantages

Fault-Tolerant Architecture: The SCHROFF MPS022 employs parallel current sharing with ±2% module-to-module balance, preventing single-point failures. If one module faults, others instantly compensate without voltage dip. Hot-swap capability allows replacements during operation, crucial for 24/7 data centers or railway signaling.
Intelligent Power Management: Real-time digital telemetry via PMBus monitors voltage/current per module, predicting failures through temperature drift analysis. Phase-loss compensation maintains output during brownouts (down to 85VAC).
Harsh Environment Resilience: Conformal-coated PCBs resist humidity and corrosive gases (ISO 12944 C4). Shock/vibration tolerance (15g/2Grms) suits rolling stock (EN 50155 S1 compliance).
Energy Optimization: Active inrush control limits startup current to 20A at 230VAC. Smart fan algorithms reduce noise to 35dBA at 50% load while maintaining thermal margins.

Application Field

The SCHROFF MPS022 secures power for critical infrastructure:

Rail Transportation: Powers onboard control systems in trains (EN 50155 certified), enduring 15g shocks and voltage dips.

Industrial Automation: Delivers redundant power to DCS cabinets in chemical plants with H₂S-resistant components.

Energy Distribution: Energizes substation RTUs across -40°C Arctic sites to +70°C solar farms.

Telecom Edge Computing: Supports 5G base stations with wide DC input (120–300VDC) for battery backup compatibility.

Medical Imaging: Provides low-noise power (<50mV ripple) for MRI control electronics (IEC 60601-1).

Defense Systems: Supplies naval radar consoles with salt fog immunity (MIL-STD-810G).

Installation and Maintenance

Pre-installation preparation: Verify subrack compatibility (3U height) and allocate ≥50mm clearance for SCHROFF MPS022 airflow. Use copper busbars (35A rating) for output distribution and torque terminals to 0.6Nm.
Maintenance recommendations: Clean air filters quarterly in dusty environments. Perform annual load testing at 110% capacity to validate redundancy. Replace power modules after 100,000 hours or if efficiency drops below 90%. Always keep one spare module pre-charged for hot-swap.
