Acme T137921 Buck-boost Transformer 1.5 Kva

Product Description

The ACME T137921 is a 1.5 KVA buck-boost transformer designed to make small adjustments to line voltage in commercial and industrial electrical systems. Buck-boost transformers step voltage up or down by a small percentage, correcting under-voltage or over-voltage conditions that would otherwise reduce equipment efficiency or cause premature failure. At 1.5 KVA, this unit is suited for single-phase loads such as motors, lighting circuits, and HVAC control systems. It is installed by licensed electricians as part of a voltage-correction or power-conditioning application. The unit weighs 30 pounds and measures 5.13 inches by 5.5 inches by 11.62 inches, making it compact enough for panel rooms and equipment closets.

Buck-boost transformers like the T137921 are commonly used in residential, light commercial, and commercial settings where incoming service voltage deviates from equipment nameplate requirements. Typical applications include correcting low voltage on long branch circuit runs, boosting voltage to HVAC equipment at the end of a feeder, or bucking high-voltage service to meet load specifications. This transformer is appropriate for new installations and retrofit projects where voltage correction is required without a full autotransformer installation.

Key Features

• 1.5 KVA capacity for single-phase voltage correction applications
• Compact footprint at 5.13 x 5.5 x 11.62 inches for space-constrained installations
• 30-pound construction suitable for wall, panel, or enclosure mounting
• Functions as buck or boost depending on wiring configuration
• Applicable to motors, lighting, and HVAC control loads

Compatibility

Designed as an OEM-style replacement or new-installation buck-boost transformer for single-phase voltage correction in light commercial and commercial electrical systems.

Installation Notes

Installation must be performed by a licensed electrician in accordance with NEC requirements. De-energize the circuit at the panel and verify absence of voltage with a meter before making any connections. Buck-boost transformers can be wired in multiple configurations to achieve different voltage adjustment ratios, so consult the wiring diagram included with the unit to confirm the correct tap selection for your application. Do not exceed the 1.5 KVA nameplate rating.
