' Product Overview '
The TX-1PH-277V-3KVA-120V-N3R-HD 277V 1 Phase Energy Efficient Distribution Transformer from Larson Electronics is powerful, reliable and designed with the environment in mind. Suitable for both indoor and outdoor applications, the TX-1PH-277V-3KVA-120V-N3R-HD provides increased reliablity and protection against critical equipment failures. The lower operating costs, lower heat emissions and lower cost of ownership make this transformer ideal for a wide range of applications and businesses. This transformer features an internal disconnect on the primary side and is designed to be portable. *PLEASE NOTE: ANY FREE SHIPPING OFFERS DO NOT APPLY TO POWER DISTRIBUTION PANELS, TRANSFORMERS, OR SUBSTATIONS* Transformer Features: With a transformer rating of 3 kVA, the TX-1PH-277V-3KVA-120V-N3R-HD distribution transformer is a single phase unit with a primary voltage of 277 V. It also provides a secondary voltage of 120 V. Featuring robust construction, this unit`s cores are manufactured with non-aging, cold-rolled silicon steel laminations using state of the art technology. This unit boasts a low cost of ownership and is highly energy efficient. Lower heat emissions mean less cooling is needed as well. The Standard NEMA Type 3R enclosure makes the unit suitable for both indoor and outdoor applications and it can be surface mounted. The unit also features 220°C insulation with a 150°C temperature rise and is rated IP24. Benefits: The TX-1PH-277V-3KVA-120V-N3R-HD distribution transformer offers many benefits to the consumer. Precision cut aluminum transformer winding material help to improve performance. The close tolerances used during manufacturing also eliminates burrs which hinder performance. Each core is specially coated to prevent the ingress of moisture and are electrically balanced to minimize axial forces during short circuit situations. This distribution transformer provides owners with significant energy savings as well as offering environmental benefits. Higher efficiency not only extends the life of the transformer, but also turn into cost savings for owners in the form of lower energy bills and decreased cost of ownership. Integrated mounting brackets make installation fast and easy and the offset outward facing installation holes allow for easy power tool access. Safety: The TX-1PH-277V-3KVA-120V-N3R-HD is a distribution transformer which means that it provides operators with an increased level of protection against electric shock. A distribution transformer can also suppress electrical noise in sensitive devices and transfer power between two circuits which must not be connected. The TX-1PH-277V-3KVA-120V-N3R-HD achieves these safety features by separating or "isolating" the powered device from the power source and insulation between the primary and secondary power sources. This distribution transformer also includes an internally mounted disconnect on the primary side for safety. Enclosure: This compact power distribution transformer is designed for portability and convenience as well as durability and includes an elevated base platform for protection from standing water and weatherproof construction that withstands direct water spray and wetness. Mounting: The TX-1PH-277V-3KVA-120V-N3R-HD is designed to be surface mounted. Applications: General purposes. Larson Electronics is a manufacturer and as such can build stationary and portable transformer systems to your specifications. Although we carry several models of power distribution transformer systems, we can deliver custom ordered units almost as quickly as our prebuilt units.
