Each type serves a specific function in the data centre power chain. Specifying the wrong type wastes capital and leaves equipment unprotected.
Isolation Transformers
Electrically separates the primary supply from the IT load, eliminating common-mode noise, ground loops, and conducted interference from the supply network. K-20 harmonic rating accommodates the high harmonic current content generated by thousands of server switching power supplies without insulation overheating.
- ✓Server rack PDU feeds
- ✓UPS input circuits
- ✓Data centre main distribution
- ✓Medical imaging power supply
Cast Resin Dry-Type Transformers
The standard for indoor data centre power distribution. Resin encapsulation eliminates oil fire risk (zero oil), passes F1 fire class test, and provides superior moisture immunity compared to conventional air-cooled dry types. Available in 11kV, 6.6kV, 3.3kV primary configurations for direct connection to DEWA HV supply.
- ✓Main HV/LV step-down
- ✓Indoor substations
- ✓Data hall power distribution
- ✓Hospital electrical rooms
Power Transformers
Heavy-duty industrial power transformers for data centre campus incoming supply, generator interface, and utility interconnection. Manufactured with low-loss silicon steel cores for minimum no-load losses — critical in facilities that run 24/7 at varying load profiles.
- ✓Utility interconnection
- ✓Generator step-up/down
- ✓Campus power distribution
- ✓Industrial plant supply
Auto Transformers
Cost-effective voltage matching for imported data centre equipment rated for 208V, 480V, or 575V connected to UAE 415V/230V supply. Also used for soft-start motor applications and UPS output voltage trimming.
- ✓208V/480V equipment matching
- ✓UPS voltage adjustment
- ✓Imported machinery compatibility
- ✓Motor soft-start circuits
Control Transformers
Dedicated voltage supply for BMS controllers, PLC panels, and automation control circuits. Isolates sensitive control electronics from the main power distribution, preventing voltage transients from generator switching or UPS transfers from resetting BMS controllers at critical moments.
- ✓BMS and DDC panels
- ✓PLC control cabinets
- ✓Data centre automation
- ✓UPS bypass control circuits
