UPS systems
Single-phase and three-phase UPS for closets, server rooms and edge racks, matched to load and runtime.
Edge & server-room power
UPS, batteries and rack power for the rooms that keep the business running
Edge sites, IT closets and small server rooms rarely get data-center attention until a battery fails. MCSL sources the replacement or the refresh, matched to your existing equipment.
What we source
Power for small rooms and edge sites
Send the model numbers of what you run today, or the load you need to support.
Replacement batteries & modules
Battery cartridges, modules and external battery packs matched to your installed UPS model.
Rack & floor PDUs
Basic, metered, monitored and switched PDUs sized to the rack’s power density and receptacle needs.
Transfer switches & surge
Rack transfer switches for dual-corded resilience, plus surge protection for distributed equipment.
Planning notes
Questions worth answering before you order
Batteries
How old are the batteries?
Manufacturer guidance puts typical VRLA UPS battery life at three to five years, shortened by heat and frequent discharges. See our UPS battery planning guide.
Fit
Replace the battery or the UPS?
Schneider Electric suggests considering a whole-unit replacement when an older single-phase UPS (over about eight years) reaches battery end of life. Send us the model and age and we will quote both.
Density
Is the PDU still right for the rack?
Higher-density equipment can outgrow the original PDU’s capacity or receptacle mix, and North American rack PDUs are typically de-rated to 80% of their input rating. See our rack PDU selection guide, or send the rack inventory and we will match options.
