We service the Delta Ultron DPS across Canada: preventive maintenance, battery replacement and emergency repair, including units the manufacturer no longer supports. We are a Canadian UPS service and supply provider, working on three-phase systems since 2012.
Scheduled visits, battery work and fault response for these systems are covered by Delta UPS maintenance and repair in Canada.
We engineer the solution: load and growth analysis, redundancy (N, N+1, 2N), runtime and battery sizing, paralleling and switchgear, and custom configurations where the standard catalogue doesn't fit. Because we supply every major brand, the Ultron DPS is one option we weigh on its merits, not the only answer.
