About Transformator
What this collection covers
UPSPLUSBATTERY.CA stocks transformers for voltage conversion, isolation, and step-up / step-down applications — industrial control panels, lab equipment requiring isolated power, medical-grade hospital-isolation transformers, and conversion of 120 V North American equipment to 220–240 V European / Asian voltage (or vice versa).
Transformers in this collection are standalone — not built into a UPS chassis. For UPS with integrated isolation transformers, see XPC isolated UPS (TX91 series with internal galvanic isolation transformer).
Transformer types
| Type | Primary use | Common configurations |
|---|---|---|
| Step-down | 208/240/480 V → 120 V | 240/120 V split-phase, 480/240 industrial |
| Step-up | 120 V → 208/240/480 V | For 240 V appliances on 120 V supply |
| Voltage-conversion (overseas) | 120 V ↔ 220/230/240 V | North American gear in Europe / Asia, or vice versa |
| Isolation transformer | Galvanic isolation between source and load | Lab, medical, sensitive instrumentation |
| Industrial control transformer | 240/480 V → 24/120 V control circuit | PLC, contactor, control-panel power |
How to choose
VA / kVA rating
Match the transformer's VA rating to load nameplate VA × 1.25 buffer. For motor-start inrush, factor 2–3× running VA on the transformer rating to handle the surge without saturating the core.
Single-phase vs three-phase
Most commercial / industrial step-down is single-phase split (240/120). Three-phase 480/208/120 is required when upstream service is three-phase or when load mix needs balanced phase distribution. Confirm primary and secondary configuration before ordering.
Isolation requirements
If the application requires galvanic separation (medical CSA C22.2 No. 60601-1, sensitive instrumentation, or to break a ground loop), specify an isolation transformer with explicit isolation rating and low leakage current. Voltage-conversion transformers without isolation should not be used where isolation is the binding requirement.
Frequency
North American transformers typically rate 60 Hz. European / Asian rate 50 Hz. Operating a 60 Hz transformer at 50 Hz can cause core saturation and overheating; vice versa is generally safer but inefficient. For mixed 50/60 Hz environments, specify dual-frequency transformers.
Installation and warranty
Most installations above ~5 kVA require licensed electrician installation per Canadian Electrical Code. Hard-wired primary and secondary connections must be in accordance with Section 26 (transformer installation). Manufacturer warranty per brand on individual product pages; UPSPLUSBATTERY 1-year support coordination.
FAQ
Transformer vs UPS?
Different functions. Transformer changes voltage / phase or provides isolation but does not store energy or ride through outages. UPS provides battery-backed ride-through. For sensitive equipment requiring both isolation and ride-through, see XPC isolated UPS (TX91 with built-in isolation transformer).
Voltage conversion for overseas equipment?
Yes — 120 V ↔ 240 V step-up / step-down transformers are common. Confirm both primary and secondary VA ratings cover the overseas equipment's nameplate × 1.25.
Step-up to run a 240 V welder on 120 V?
Possible but typically inefficient — a 7.5 kW welder requires a 7.5+ kVA step-up transformer drawing ~75 A on the 120 V primary, which often exceeds typical 15 A or 20 A receptacles. Direct 240 V circuit installation is usually the better solution.
Isolation for medical equipment?
Medical isolation transformers carry specific certifications (CSA C22.2 No. 60601-1 / UL 60601-1) for patient-care environments. For UPS-integrated medical isolation, see TX91 / TX91L in XPC isolated UPS.
Three-phase to single-phase?
Three-phase to single-phase converters and transformers are available but require careful sizing — a single-phase load on three-phase service should ideally be balanced across phases at the panel. Consult a licensed electrician for any three-phase work.
