ABB UFC718AE101 / HIEE300936R0101 – Wide Input Range (85–264 VAC) Power Module for Automation

Description

Application Scenarios

At a nuclear power plant in Scandinavia, a sudden grid voltage dip caused multiple non-redundant power supplies in auxiliary control panels to shut down, triggering a partial turbine trip. After upgrading to ABB UFC718AE101 modules mounted on HIEE300936R0101 bases—with active parallel redundancy—the system maintained full functionality during subsequent grid events. The power supply’s wide input range (85–264 VAC) and >20 ms hold-up time bridged the gap until backup generators engaged. Crucially, its hot-swap capability allowed engineers to replace a failing unit during operation without interrupting reactor monitoring—a testament to how robust power design underpins functional safety in high-stakes environments.

Note: The UFC718AE101 cannot operate standalone—it must be mounted on a compatible base like HIEE300936R0101. which routes power and enables redundancy.

Technical Principles and Innovative Values

Innovation Point 1: True Hot-Swap Architecture – The HIEE300936R0101 base includes pre-charge circuitry and connector sequencing that prevents bus disruption during module insertion/removal—critical for 24/7 operations.

Innovation Point 2: Active Current Sharing – When configured in redundant mode, multiple UFC718AE101 units share load equally, reducing thermal stress and extending service life.

Innovation Point 3: Universal Input – Accepts both AC and DC mains (e.g., 125 VDC battery systems in substations), offering flexibility across energy, water, and transportation sectors.

Innovation Point 4: Integrated Diagnostics – LED indicators show input presence, output status, and fault conditions; optional relay contact (on some variants) enables remote monitoring via PLC.

Application Cases and Industry Value

In a Middle Eastern desalination plant, ambient temperatures exceeding 50°C caused premature capacitor failure in standard power supplies. After switching to UFC718AE101 / HIEE300936R0101 units—selected for their extended temperature rating and convection-cooled design—MTBF increased from 18 to over 60 months. The plant’s control system achieved 99.99% uptime over three years, directly supporting water security goals.

Similarly, in a U.S. rail signaling center, the ability to run the UFC718AE101 from a 125 VDC battery bank ensured signal logic remained powered during commercial AC outages—meeting FRA safety mandates without additional converters.

Installation, Maintenance, and Full-Cycle Support

Installation requires mounting the HIEE300936R0101 base on a DIN rail, then firmly inserting the UFC718AE101 until it latches. Input/output wiring uses screw terminals rated for 0.5–4 mm² conductors. For redundant operation, connect outputs of two or more units via the base’s common bus bars—no external diodes needed.

Maintenance is minimal but should include periodic checks for dust accumulation (which impedes cooling) and terminal tightness. If the red “Fault” LED illuminates, verify for short circuits downstream before replacing the module. Thanks to hot-swap design, replacement takes <2 minutes with no system power-down.
