Dongan 85-4040SH 1.5KVA 277-120/240 GP TRANSFORMER

Dongan offers single phase ventilated transformers from .50kVA to 5kVA and encapsulated transformers from .250kVA through 25kVA. Our enclosures are NEMA 3R as standard with only some exceptions at the smallest kVA. These transformers can be wall mounted or floor mounted cabinet style depending upon the kVA rating. These are UL and CUL listed and are copper wound through 25kVA. We offer aluminum wound transformers starting at 7.5kVA through 100kVA as standard off the shelf. Larger custom transformers are available. All of our transformers have an electrostatic shield between the primary and secondary for transient noise reduction. Insulation system are 105 C, 180 C or 220 C depending upon the series of transformer. Electrostatic shield between primary and secondary windings provides cleaner output voltage and helps to reduce spikes and transients.

• Aluminum windings connect to bus bar style terminations equipped with NEMA standard holes for compression style or ring terminals.
• UL Class 220C insulation system with a 150C temperature rise at full load and a maximum ambient of 40C.
• NEMA Type 3R, ventilated, cabinet style, floor mount enclosure suitable for indoor or outdoor use.
• No extra rain shields required for outdoor use. May also be used in banks of2 or 3 units for three phase isolation or autotransformer applications.
• Vibration dampening pads provide quiet operation.
• Wall Mounting brackets are available in sizes up to50 kVA
• Ground studs provided for bonding compatibility with both metallic and nonmetallic conduit.
