1-Phase Buck/Boost Step-Up Explosion Proof Transformer - C1D1, C2D1 - 208V Primary/240V Secondary

Part # ETX-BBT-208V-240V-23.4A-2X0.75S    Price: $4,061.50

Spec Sheet   Hoja de Especificaciones   

The ETX-BBT-208V-240V-23.4A-2X0.75S single phase step-up Explosion Proof Buck and Boost Transformer from Larson Electronics is powerful, reliable and designed with the environment in mind. Suitable for both indoor and outdoor applications, the NEMA 4X-rated device provides increased reliability, higher efficiency, protection against critical equipment failures and an extra level of protection by isolating the power source from the connected device. This explosion proof unit is housed in a cast aluminum enclosure and features terminal strips for connecting input/output wiring.


Transformer Features: The ETX-BBT-208V-240V-23.4A-2X0.75S explosion proof buck and boost transformer is a single phase unit with a 5.53 KVA rating and a primary voltage of 208V AC, using a maximum of 26.6 amps on the primary side. This explosion proof step-up transformer has a secondary voltage of 240 and provides up to 23.4 amps available on the secondary side. This unit boasts a low cost of ownership and is highly energy efficient. Lower heat emissions mean less cooling is needed as well. The explosion proof device features a 180°C insulation with a 115°C temperature rise.

Construction: The copper winding in the ETX-BBT-208V-240V-23.4A-2X0.75S are formed from high quaility magnetic copper wire 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. Buck and boost transformers are designed to maximize the performance and life of electrical equipment. The ETX-BBT-208V-240V-23.4A-2X0.75S is encapsulated in cast aluminum and includes a watertight gasket for a NEMA 4X protection rating.

Benefits: The ETX-BBT-208V-240V-23.4A-2X0.75S explosion proof buck/boost step-up transformer offers many benefits to the consumer. Buck/boost transformers pass the majority of the load voltage directly through the transformer, only transforming a small percentage of the load. Due to this technology, a smaller and quieter step-up transformer is manufacturered and uses less materials. This 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. Installation and maintenance costs are reduced due to the smaller form factor, and less overall space requiorments are decreased. In addition, these step-up transformers operate quieter than a standard autotransformer of the same capacity.

Installation/Wiring: Installation is simple. Terminal strips are available for completing input and output wiring connections.

Mounting: This explosion proof buck/boost transformer is compatible with surface mount applications. Mounting is provided by four ears, two per side of the enclosure. The device features a removable backplate seamless installation. Two NPT hubs are factory tapped to allow conduit entry into the enclosure. The hub sizes and locations are as follows: two 3/4" NPT on the south side.

Applications: Hazardous locations, flammable work sites, oil and gas facilities, agricultural operations, refineries, grain storage centers, air conditioners, lighting systems, heating elements, motor applications and other applications that that require the ability to power loads that differ from the available line voltage.

Limitations: While there are many benefits to a buck/boost transformer, there are some limitations to consider. This explosion proof transformer will only transform voltages, it will not convert phases, has no circuit isolation, and does not allow use of the neutral. If any of these limitations apply to you, you will need a standard transformer. Please see below link for our standard line of industrial transformers or our line of phase converters.

Note on Phases: This explosion proof buck/boost transformer is a single phase step-up transformers. For three phase transformers, click on the following links:
