MTL Instruments MTL8913-PS-AC – Dual Voltage AC System Power Supply | MTL 8000 Series
Engineering Background
The MTL 8000 series is MTL Instruments’ flagship platform for intrinsically safe signal conditioning and power distribution in hazardous-area process automation. Designed to IEC 60079 standards, the series is widely deployed in oil & gas, petrochemical, and chemical processing facilities where reliable, certified power delivery is non-negotiable. The MTL8913-PS-AC is the dual-voltage AC mains power supply module that anchors the entire backplane ecosystem, converting AC line power into the regulated DC rails required by all 8000-series I/O and signal-conditioning modules.
Product Positioning
The MTL8913-PS-AC is the recommended primary power source for MTL 8000 series DIN-rail backplanes. It accepts a wide-range AC input, delivers dual regulated DC output rails, and supports hot-swap replacement without interrupting field-side signals — making it the preferred choice for procurement engineers specifying high-availability control architectures in classified hazardous areas.

Engineering Advantages
- Universal AC Input: 85–264 V AC wide-range input eliminates the need for separate 110 V / 220 V SKUs, simplifying global procurement.
- Dual Regulated DC Rails: Simultaneously powers both the logic and field-side circuits of MTL 8000 modules from a single supply unit.
- Hot-Swap Capable: Designed for in-service replacement on the MTL 8000 backplane without de-energising field instruments.
- Hazardous-Area Certified: ATEX/IECEx certification supports direct installation in Zone 2 / Div. 2 classified areas (verify enclosure rating).
- High MTBF: Industrial-grade components and conservative thermal design deliver long service life in continuous-duty process environments.
- Compact DIN-Rail Form Factor: Integrates seamlessly into standard 35 mm DIN-rail panels alongside MTL 8000 I/O modules.
System Architecture & Signal Flow
The MTL8913-PS-AC mounts directly onto the MTL 8000 series backplane. AC mains enters the module through a dedicated terminal block; internal switching circuitry converts and regulates the input to dual DC output rails distributed across the backplane bus. Each MTL 8000 I/O or signal-conditioning module draws power from these rails without individual external wiring. The dual-rail architecture ensures that a fault on one rail does not collapse the other, supporting partial-redundancy designs. For full power redundancy, two MTL8913-PS-AC units can be installed in parallel with appropriate diode-OR circuitry per MTL application guidance.
