Industrial Power Supply Solution – RELIANCE ELECTRIC 45C920 | Automax Series
Where This Product Is Used
The RELIANCE ELECTRIC 45C920 Power Supply Module is a core component of the Automax DC Drive control system, widely deployed across demanding industrial environments. Engineers and plant managers specify this module in:
- Steel mills & metal processing lines – powering DC drive controllers for rolling mills, coilers, and tension reels where precise voltage regulation is critical
- Paper & pulp manufacturing – sustaining uninterrupted control power to winder and unwinder drive systems operating 24/7
- Mining & mineral processing – supplying regulated DC bus power to conveyor drive panels in high-vibration, dusty environments
- Chemical & petrochemical plants – providing stable control-circuit power in hazardous-area adjacent panels requiring reliable, isolated supply rails
- Water & wastewater treatment – maintaining pump drive control systems where power interruptions cause process upsets
- Automotive assembly lines – supporting multi-axis DC drive systems on transfer lines and press controls

Why Engineers Specify This Model
- Drop-in replacement – direct form-fit-function substitute for failed 45C920 units; no re-wiring or firmware changes required
- Proven field reliability – the Automax platform has accumulated decades of runtime in heavy industry; the 45C920 PSU is a known-stable component
- Isolated output rails – reduces ground-loop noise coupling into sensitive control logic, improving drive stability
- Minimizes downtime cost – a failed PSU can halt an entire production line; having a verified spare on-hand reduces MTTR from days to minutes
- Supports legacy fleet maintenance – many Automax installations remain in service; sourcing OEM-equivalent modules extends asset life without full drive replacement
