HIRSCHMANN RPS80EEC Replacement for MICE Series

Product Overview

HIRSCHMANN RPS80EEC Replacement for MICE Series: Seamless Transition from Legacy Power Infrastructure

The HIRSCHMANN RPS80EEC is a dedicated redundant power supply module engineered for the MICE Series managed industrial Ethernet switches. As aging control-room infrastructure reaches end-of-service milestones, plant engineers and system integrators increasingly require a verified, drop-in replacement that preserves existing wiring layouts, DIN-rail footprints, and 24 VDC or 48 VDC bus architectures without forcing a full cabinet redesign. The RPS80EEC delivers exactly that: a smooth, low-risk migration path from obsolete or discontinued power supply units to a fully supported, in-production module backed by a 12-month warranty.

In brownfield retrofit projects, the RPS80EEC slots directly into the same redundant power input terminals used by earlier HIRSCHMANN MICE power supply variants. Field technicians report that terminal block wiring—including PE, L+, and M connections—maps identically to predecessor units, eliminating the need to re-label or re-route existing cable harnesses. This is particularly valuable in process-critical environments such as water treatment SCADA panels, railway trackside cabinets, and oil-and-gas DCS marshalling rooms where unplanned downtime carries significant operational cost.

Seamless Upgrade Solutions

A successful MICE Series power infrastructure upgrade rarely involves the RPS80EEC in isolation. In practice, the redundant power supply works in concert with the broader switch and I/O ecosystem. When migrating a legacy Ethernet backbone, engineers typically pair the RPS80EEC with HIRSCHMANN MICE switches such as the MS20 or MS30 managed switch family, which share the same backplane power bus architecture. Where the existing cabinet also houses older RS20 or RS30 compact switches, the RPS80EEC’s wide-range input voltage ensures compatibility across mixed-generation deployments without requiring separate PSU variants for each switch tier.

On the communications side, projects that integrate PROFINET or Modbus TCP over the MICE backbone will often simultaneously upgrade the HIRSCHMANN SPIDER II or OCTOPUS series media converters and fiber uplink modules. The RPS80EEC’s stable 80 W output provides sufficient headroom to power PoE-capable switch variants and their connected field devices, including remote I/O stations and distributed HMI panels mounted at machine level. In cabinet layouts where space is constrained, the module’s slim DIN-rail profile allows it to coexist with HIRSCHMANN BAT series wireless access points or EAGLE series security appliances without requiring panel expansion.

For projects involving PLC migration—such as transitioning from a SIEMENS S5 or S7-300 rack to a modern S7-1500 or SIEMENS ET 200SP distributed I/O architecture—the RPS80EEC ensures the Ethernet switching layer remains stable and fully powered throughout the cutover window. Similarly, in ABB AC500 or Schneider Electric Modicon M340 environments where the MICE Series provides the plant LAN backbone, replacing an aging power supply with the RPS80EEC avoids the risk of switch brownouts during peak load cycles. Signal isolators and surge protection modules installed on the same DIN rail are unaffected by the swap, as the RPS80EEC’s output ripple and transient suppression characteristics meet or exceed the original specification.

Retrofit Guidance FAQ

Q: Can I replace the existing MICE power supply without powering down the entire switch?
A: The RPS80EEC is designed for hot-swap-capable redundant configurations. When a second RPS80EEC or compatible PSU is already installed and active on the redundant bus, the failed or legacy unit can typically be removed and replaced without interrupting switch operation. Always verify the redundant bus is carrying full load before initiating the swap.

Q: Do I need to modify the terminal block wiring?
A: No. The RPS80EEC uses the same PE / L+ / M screw terminal layout as predecessor MICE power supply modules. Existing wire ferrules and cable labels remain valid. Torque the terminals to the manufacturer-specified value (typically 0.5–0.6 Nm) after insertion.

Q: Is the RPS80EEC compatible with both 24 VDC and 48 VDC supply rails?
A: Yes. The wide-range DC input accepts both 24 VDC and 48 VDC bus voltages, making it suitable for mixed-voltage cabinet designs common in railway and utility SCADA applications.

Q: Will my existing PROFINET or Modbus TCP configuration require changes after the PSU swap?
A: No. The RPS80EEC is a power module with no network interface. Switch firmware, IP addressing, VLAN configuration, and protocol settings are stored in the switch’s non-volatile memory and are unaffected by a power supply replacement.

Q: What is the physical installation space requirement?
A: The RPS80EEC mounts on a standard 35 mm DIN rail (EN 60715) and occupies the same width as the original MICE PSU slot. No additional panel space or bracket modification is required for a direct replacement.

Q: How do I verify the replacement unit before installation?
A: Each RPS80EEC shipped from TOPNLMS undergoes pre-shipment functional testing including output voltage verification, load regulation check, and redundancy bus connector inspection. A test report is available upon request.

Warranty Assurance

Every HIRSCHMANN RPS80EEC supplied by TOPNLMS is covered by a 12-month warranty from the date of shipment. This warranty covers manufacturing defects, functional failures under normal operating conditions, and DOA (dead-on-arrival) units. In the event of a warranty claim, TOPNLMS provides a replacement unit or full refund within the agreed lead time, with no additional freight charge to the buyer for the first warranty exchange.

Pre-shipment inspection includes output voltage and current verification, visual inspection of connectors and housing, and functional burn-in testing where applicable. Units are packed in anti-static, shock-resistant packaging suitable for international air and sea freight. Typical dispatch time from our Xiamen warehouse is 1–3 business days after payment confirmation, with DHL Express, FedEx, and UPS options available for time-critical plant shutdowns.

For procurement teams requiring documentation, TOPNLMS can provide a commercial invoice, packing list, certificate of origin (Germany), and test report. Bulk orders of 5 units or more qualify for priority allocation and dedicated account support.
