Service by brand
We maintain and repair ABB three-phase UPS systems: Conceptpower DPA and its UL version, DPA 250 S4, DPA UPScale ST and RI, MegaFlex DPA and PCS100. Older GE-branded lines have their own page. We are a Canadian UPS service and supply provider since 2012, not ABB. Same-day service in Montreal, Quebec City, Toronto and Ottawa; 24 to 48 hours elsewhere in Canada.

Three-phase families we work on, each with its model page:
ABB states that on the DPA 250 S4, maintenance, service and all cable connections can be managed from the front of the frame cabinet, with no side or rear access required. A yearly visit is the baseline: batteries measured block by block, fans and air filters, connection torque and a thermal scan under load, the event log and settings, and a written report with every reading next to the previous visit.
In ABB's DPA architecture the UPS modules operate completely independently of each other, so one failed module does not take the others down; on the Conceptpower DPA, modules are rated 30, 40 or 50 kVA. We diagnose from the alarm history and the measurements, quote the part and the labour before fitting anything, and test the unit back to normal operation.
Every service line we offer, ABB systems included, is listed on the services overview, and the trade-offs of module-based frames are covered on the modular systems page.
The runtime of a DPA system depends on the weakest block in each string. We replace battery strings and cabinets, measure each block before and after, and size replacement strings to the runtime you need. A string is replaced as a set: one new block in an aged string ages to match the others.
GE-branded SG Series, SitePro and LP33 systems are covered on GE UPS service. When a replacement makes more sense, we size a current system for the measured load and plan the cutover.
Planning the replacement: replacing a discontinued three-phase UPS.
A unit still under the manufacturer's warranty, or a new system awaiting its first start-up, goes through the manufacturer first. Maintenance, repairs and batteries after that can be done by us.
Same-day service in Montreal, Quebec City, Toronto and Ottawa; 24 to 48 hours elsewhere in Canada. We reply and quote within 4 business hours. Tell us the brand, the model and the symptom or the visit you need, and the quote comes back with the scope and the date.
We also service GE, APC / Schneider and Eaton three-phase systems.
Yes, the IEC and UL versions, along with the DPA 250 S4, DPA UPScale ST and RI, MegaFlex DPA and PCS100.
ABB states that DPA modules operate completely independently of each other, so with redundant modules the others keep carrying the load while one is replaced.
