Transformers
Mobile transformer power modules for rental duty. Isolation transformers with built-in distribution, cam-lock-only isolation units, and autotransformers for matching 480 V generators to 600 V loads. Every unit is weatherproof, forkliftable and built on the same cam lock and gland system as the rest of the SBP range.
Transformers with built-in power distribution
15 to 300 kVA ·5 models
Step 480 or 600 V down to 120/208 V and distribute it from the same enclosure. Panelboard, breakers and Eco Power gland plates are built in, so one unit replaces a transformer, a panel and the cabling between them.
