Key facts

What we service

Three-phase families we work on, each with its model page:

Discontinued families we still maintain:

Preventive maintenance

Socomec states that the MASTERYS GP4 has been engineered for safe and fast maintenance by front access, with advanced brick replacement, which keeps most of the visit on the front of the cabinet. 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.

Repair

On MASTERYS and MODULYS systems, a failed subassembly is replaced as a unit and the system is returned to double conversion. 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.

Batteries

Socomec equips the MASTERYS GP4 with an Expert Battery System (EBS) to protect battery life and back-up time; its readings are part of our visit. 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.

Large Socomec installations fall under our high-capacity three-phase service, and replacement blocks for MASTERYS and DELPHYS cabinets can be matched in the replacement battery catalogue.

Legacy and discontinued models

MASTERYS MC, DELPHYS MX and DELPHYS BC systems are no longer sold. We keep them in service while parts and batteries can be sourced. When a replacement makes more sense, we size a current system for the measured load and plan the cutover.

When the manufacturer should do the work

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.
