Acme Electric T181048 Buck Boost Transformer 0.1 Kva

Product Description

The ACME ELECTRIC T181048 is a single-phase buck-boost transformer rated at 0.1 KVA, designed to step voltage up or down in electrical distribution and equipment-feed applications. It accepts a primary voltage of 120 x 240 volts and delivers a secondary voltage of 12 or 24 volts, making it well suited for small voltage-correction tasks where a full isolation transformer is unnecessary. The totally enclosed construction and NEMA 3R enclosure rating qualify it for outdoor installation. Operating at 50/60 Hz, this unit is installed by licensed electricians handling commercial lighting, HVAC controls, motor circuits, and similar low-voltage correction work.

This transformer is applicable in both single-phase and three-phase distribution systems requiring minor voltage adjustment. Its compact footprint and outdoor-rated enclosure make it a practical choice for rooftop HVAC equipment, outdoor signage feeds, and light commercial panel applications where space is limited and weather exposure is a factor. Output current is 8.32 amps at 12 volts or 4.16 amps at 24 volts, covering a range of small control-circuit and lighting loads.

Key Features

• 0.1 KVA power rating suitable for small voltage-buck or voltage-boost correction tasks
• Primary voltage of 120 x 240 V with secondary output of 12/24 V
• Totally enclosed construction with NEMA 3R outdoor-rated enclosure
• Dual-frequency rated at 50/60 Hz for broad application compatibility
• UL and CSA listed for code-compliant installation
• Compact dimensions minimize space requirements in tight enclosures or rooftop installations

Compatibility

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

Installation Notes

Installation should be performed by a licensed electrician in accordance with the NEC and applicable local codes. De-energize and lock out the circuit before making any wiring connections. The NEMA 3R enclosure permits outdoor mounting but should be positioned to minimize direct water impingement where possible. Verify primary and secondary voltage tap selections match the circuit requirements before energizing.
