UL Listed Explosion-Proof Driver 30 W, 70.7V Transformer

Ideal Use Cases

The AtlasIED MLE-1T is designed for paging and notification applications that require an explosion-proof, UL listed compression driver. It combines the driver with a 30-watt 70.7V transformer and is intended for use with AtlasIED HLE/MLE horns. The documented horn matches are the HLE_MLE-30 and HLE_MLE-32, providing two specifically identified configurations for system planning.

This model is suited to projects in which the specified requirements include UL listing, explosion-proof construction, a 70.7V transformer, and compatibility with one of the supported AtlasIED horns. Its defined frequency response, transformer taps, continuous power rating, and horn-specific sensitivity figures provide concrete information for evaluating it within a paging or notification design.

Why Choose This Model

The MLE-1T brings the compression driver and 70.7V transformer together in one model. Its transformer offers five documented power taps: 1.8, 3.7, 7.5, 15, and 30 watts at 70.7V. This range provides multiple available settings while maintaining a maximum continuous power rating of 30 watts.

Compatibility is clearly stated rather than broadly implied. The driver mounts the AtlasIED HLE_MLE-30 and HLE_MLE-32 horns, and performance data is supplied for both combinations. Sensitivity is rated at 107 dB when used with the HLE_MLE-30 horn and 110 dB when paired with the HLE_MLE-32 horn. These published figures allow the two supported horn combinations to be compared using product-specific data.

Installation and Integration

Integration begins with selection of either the HLE_MLE-30 or HLE_MLE-32 horn. The applicable horn specification should then be reviewed for the completed product’s dimensions and dispersion, as those details depend on the selected horn rather than the driver alone. This distinction is important when planning the physical configuration and coverage characteristics of the assembled product.

The transformer’s available taps are 1.8W, 3.7W, 7.5W, 15W, and 30W at 70.7V. The appropriate documented tap can therefore be selected according to the requirements of the intended paging or notification installation. The supplied data does not specify dimensions, weight, wiring accessories, or mounting hardware for the driver, so those items should be confirmed separately when preparing the complete installation.

Performance Highlights

The MLE-1T has a stated frequency response of 300Hz to 14kHz and a continuous power rating of 30 watts. Its sensitivity depends on the attached horn: 107 dB with the HLE_MLE-30 and 110 dB with the HLE_MLE-32. That three-decibel difference makes horn selection a documented performance consideration rather than only a physical compatibility choice.

Five transformer taps extend from 1.8 watts through the full 30-watt rating. Together, the frequency response, horn-specific sensitivity data, and selectable 70.7V power taps define the principal operating characteristics provided for this model. Final dimensions and dispersion remain specific to the selected horn and should be taken from that horn’s specifications.

What Makes It Different

The distinguishing combination is an explosion-proof, UL listed compression driver supplied with a 30-watt 70.7V transformer. The MLE-1T also provides named compatibility with two AtlasIED horn models and publishes a separate sensitivity value for each pairing. This makes the listing more precise than a general driver description because it identifies the compatible horns, available transformer taps, continuous rating, frequency response, and resulting sensitivity figures.

Its five power taps offer more configuration choices than a single fixed power setting, while the 30-watt continuous rating establishes the stated upper rating. The model remains focused on its intended role: driving supported AtlasIED HLE/MLE horns for paging and notification.

Final Assessment

The AtlasIED MLE-1T is a purpose-defined choice for a system requiring an explosion-proof, UL listed compression driver with a 70.7V transformer. It offers a 30-watt continuous rating, selectable taps from 1.8W to 30W, and a 300Hz to 14kHz frequency response. Compatibility with the HLE_MLE-30 and HLE_MLE-32 horns, together with sensitivity data for both pairings, provides a clear basis for selecting the appropriate configuration. For final system dimensions and dispersion, use the specification for the chosen horn.
