Make AIS Disconnector Control Simple Again — How the ODES PCM972 Cuts Wiring, Components, and Commissioning Time
A unified motor-control platform that replaces “two contactors + motor protector” with clean, deterministic, and visualized control logic In many AIS (air-insulated switchgear) disconnector applications, control wiring is still built around two contactors, a motor protector, and a handful of relays and timers. It works — but it creates wiring sprawl, fragile interlocking chains, inconsistent protection behavior, and difficult commissioning . The PCM972 Integrated Motor Co

Fast-Swap Energy Storage Control for HV Switchgear — How ODES PSME109 Turns “Replace the Device, Not the Wiring” Into Real Engineering
Modern utilities, especially in fast-pace operational environments, are moving toward standardized, modular, and quickly replaceable control architectures. Visit www.odes-electric.com to explore how ODES is supporting this transition with integrated HV motor-control solutions. In many high-voltage switchgear projects, energy-storage motor circuits are still stitched together with timers, thermal relays, and contactors . They function, but they don’t scale. Any modificat

Smarter Energy Storage Control Starts Here — How the ODES PSME309 Simplifies High-Voltage Switchgear Motor Circuits
In most primary high-voltage switchgear, energy storage motor circuits are still pieced together with timers, contactors, and thermal relays . These discrete setups “work,” but they are hard to modify, lack full protection visibility, and depend heavily on individual experience. The ODES PSME309 Energy Storage Controller changes that — transforming “handcrafted wiring logic” into data-driven, parameter-based control . It integrates protection, configuration, and m

ODES PCM965- The New Standard for Ring Main Unit Motor Control
Motor control in medium-voltage ring main units (RMUs) is often underestimated. In reality, it’s not just about “making the motor turn.” For engineers, what matters is stable positioning, safe interlocking, quick diagnostics , and the ability to perform reliably under high EMI, long-cable, or harsh environmental conditions. This is the engineering philosophy behind the ODES PCM965 Series , a unified three-branch platform developed to cover C-cabinet (load switch), F

How the ODES PCM Three-Position Controller Redefines On-Site Parameter Setting
In factory tests, everything runs smoothly. But on-site, things change — actuator resistance shifts, travel time lengthens, and stall thresholds no longer fit. Before long, engineers are unpacking laptops, installing drivers, and racing against daylight to finish re-tuning. Even worse, after several years of service, spring fatigue, linkage wear, and backlash make original parameters obsolete. Reconnecting communication cables and finding the right software version just t

GIS Motor Control, Solved: PCM Three-Position Controller for Faster, Precise, Steady Operation
Modern gas-insulated switchgear (GIS) relies on more than just motor actuation — it demands stability, precision, and diagnostic intelligence under harsh field conditions. Engineers face daily challenges such as unreliable positioning, misoperation, wiring complexity, and poor fault visibility. The PCM Three-Position Programmable Motor Controller from ODES is purpose-built to solve these issues through an integrated, standardized, and EMC-hardened design . Learn mor
