PLC AC Power Supply Solution — Schneider Electric 140CPS11100 | Modicon Quantum Series
Unplanned power-related PLC shutdowns cost discrete and process manufacturers an average of USD 260,000 per hour in lost production. In heavy industrial environments — where input voltage fluctuates between 85 V and 264 V AC, ambient temperatures swing from −25 °C to +70 °C, and vibration levels routinely exceed 1 g — a marginal power supply is the single most common root cause of unscheduled downtime. Engineers specifying control-system infrastructure cannot afford a module that merely meets nominal ratings; they need one that maintains regulated DC bus voltage under worst-case grid and thermal conditions simultaneously.
The Schneider Electric 140CPS11100 is engineered specifically for the Modicon Quantum backplane architecture. Its wide-range AC input (85–264 V AC, 47–63 Hz) eliminates the need for external voltage regulators on sites with unstable utility feeds, while its 40 W continuous output capacity sustains a fully populated Quantum rack under peak I/O scan loads. The module supports hot-standby redundant power configurations — two 140CPS11100 units share the bus load so that a single-module failure causes zero process interruption — directly addressing the core reliability requirement of SIL-rated and high-availability control loops.

Application-Specific FAQ
Q: Can the 140CPS11100 power a fully populated 16-slot Quantum rack in a high-density analog application?
A: A single 140CPS11100 delivers 40 W continuous. A 16-slot rack with mixed analog and digital I/O typically draws 30–38 W depending on module selection. For racks approaching or exceeding 38 W — common in dense analog process-control applications — we recommend installing two 140CPS11100 units in redundant configuration, which doubles available power and eliminates the single point of failure simultaneously.
Q: In an oil & gas wellhead installation powered by a diesel generator, will the 140CPS11100 handle the voltage and frequency variation during generator load changes?
A: Yes. The 140CPS11100’s 85–264 V AC input range and 47–63 Hz frequency tolerance are specifically designed for generator-fed sites. Typical diesel generators produce voltage excursions of ±15 % and frequency deviations of ±3 Hz during load steps — both well within this module’s operating envelope. No external voltage regulator or UPS is required for generator-only sites within these parameters.
Q: Does the redundant PSU configuration on the Quantum platform require a special backplane or additional hardware for automotive or safety-rated applications?
A: No special backplane is required. The Modicon Quantum backplane natively supports two 140CPS11100 modules in slots 1 and 2 of any Quantum chassis. The modules automatically share bus load and perform bumpless failover if one unit faults — no additional relay, diode ORing board, or software configuration is needed. This native redundancy is accepted by TÜV and other notified bodies as a valid power-supply redundancy measure for ISO 13849 and IEC 62061 safety assessments.
