When DC Is Missing, ODES Delivers Reliable Control Power

During substation commissioning in Inner Mongolia, engineers encountered a critical obstacle: the site had no DC power supply available.
Without DC, the breaker operating circuits could not function, and protection devices could not be energized—bringing the entire project to a standstill. Building a temporary DC system would have been costly and time-consuming, risking major delays.
This scenario is common in switching stations and temporary commissioning sites:
Breaker operating mechanisms require stable DC supply.
Breaker energy storage motors demand short-duration high-current output.
Emergency procurement or installation of a DC system is often impractical.
ODES Rapid Response
At the point of potential delay, the customer turned immediately to ODES, trusting decades of field experience and proven responsiveness.
Within 48 hours:
Site parameters were confirmed.
A configuration plan based on prior validated projects was provided.
26 DIN-rail mounted control power supplies were delivered on-site.
Installation took only minutes. One ODES power suuply unit provided stable 220 V DC output, enabling:
Successful breaker energy storage,
Normal operation of protection devices,
On-schedule project commissioning with zero delay.
As the customer remarked: “Fortunately we had ODES—otherwise this project would have been in serious jeopardy.”
Why ODES?
Immediate readiness: DIN-rail installation, operational within minutes.
High performance: Wide temperature range (−40 °C to +70 °C), EMC compliance, built-in short-circuit and overload protection.
Efficient and cost-controlled: One supply per cabinet avoids waste and optimizes cost.
Field-proven reliability: Designed for breaker operating circuits, breaker energy storage, and protection device supply.
ODES power supply products are more than emergency tools—they are practical, field-ready assets engineered for the realities of substation and industrial power environments.
Applications Beyond Emergencies
The same ODES control power supply products are now widely deployed as standard in:
Switching stations and ring main units without DC systems.
Temporary commissioning, field testing, and emergency maintenance.
Cabinets supplying multiple protection and automation devices simultaneously.
Motor and valve actuation circuits requiring inductive load startup capability.
Unexpected challenges are inevitable in power engineering projects. A truly reliable partner delivers not just equipment, but timely, field-validated solutions.
With over 30 years of engineering experience, ODES ensures that when DC supply is missing, reliability is not. This commitment is supported not by promises but by a closed-loop process of requirements analysis, definition, validation, and verification.
