Main Features and Advantages
High-current, tightly regulated 24 VDC output: The Honeywell 51198685-100 delivers a full 20 A (480–520 W) at 24–26 VDC with ±1% output accuracy and ripple no greater than 100 mV peak-to-peak. This clean, stable DC rail powers multiple Series C modules — including C300 controllers, I/O cards, and communication units — from a single supply, reducing the number of separate power sources in the cabinet.
Universal wide-range AC input: With a 100–240 VAC (47–63 Hz) input window, the SPS5710-2-LF accommodates global mains voltages and tolerates the fluctuations, sags, and momentary interruptions common in industrial power distribution. The wide input range simplifies spare-parts logistics across multinational plants and eliminates the need for site-specific input transformers in most cases.
Redundancy and hot-swap for continuous availability: The Honeywell 51198685-100 supports N+1 parallel redundant operation. When two units are installed and fed from independent AC circuits, a failure in one supply is seamlessly absorbed by the companion, preventing loss of the 24 VDC bus. With the redundant configuration in place, either module can be hot-swapped — removed and reinserted — without shutting down the controller, dramatically reducing mean time to repair (MTTR) and avoiding process upsets.
Comprehensive built-in protection: The SPS5710-2-LF integrates overvoltage lockout at 28 VDC, current-limited “hiccup” overcurrent behavior, short-circuit protection, and input under/overvoltage lockout. These functions protect both the supply itself and every downstream Series C module, while EMI/RFI filtering prevents noise propagation onto the DC bus and into sensitive analog I/O.
High efficiency and fanless reliability: At ≥85% conversion efficiency (full load, 230 VAC), the Honeywell 51198685-100 minimizes heat generation and energy loss, reducing cabinet cooling load. Its natural-convection, fanless design eliminates moving parts — a major contributor to MTBF — making the supply exceptionally reliable in dusty or hard-to-access installations.
Extreme-environment and hazardous-area rating: Rated for -40 °C to +70 °C (with linear derating above 65 °C), the Honeywell 51198685-100 starts and operates reliably in sub-zero, high-heat, and remote-field conditions. With FM, ATEX, and IECEx approvals (Class I, Division 2, Groups A–D, T4; Ex nA nC IIC T4 Gc), the SPS5710-2-LF is suitable for installation in hazardous areas common to oil & gas, refining, and petrochemical facilities.
