1-Phase Buck Boost Larson Transformer 245V/220V, 22.89‑68.67A Options

Description

Product Overview

The Larson 1-Phase Buck/Boost Isolation Transformer is engineered for high‑performance power conversion in demanding industrial environments. With a 245 V primary input and a 220 V secondary output, the unit accommodates three selectable current ratings—22.89 A, 34.33 A, and 68.67 A—allowing users to match the transformer to the exact load requirements of their equipment. Constructed from a robust steel enclosure, the transformer meets UL and IEC standards for safety and durability, and its compact footprint of 21 × 21 × 11 inches (26 lb) enables installation in confined spaces without sacrificing thermal performance. The design incorporates a high‑efficiency magnetic core that minimizes hysteresis losses, delivering stable voltage regulation across a wide frequency range of 50 Hz to 60 Hz. Integrated terminal blocks provide secure, tool‑free connections for both primary and secondary wiring, while the built‑in surge protection safeguards downstream devices from transient spikes. This transformer is ideal for applications such as motor drives, CNC machines, test rigs, and any system that requires precise voltage stepping while maintaining electrical isolation between input and output circuits.

Usage

Designed for versatility, the transformer can be deployed in a variety of industrial settings. In manufacturing plants, it powers conveyor control panels, programmable logic controllers, and sensor arrays that demand clean, isolated power to prevent ground loops and interference. In laboratory environments, researchers rely on its stable output for precision instrumentation, signal generators, and high‑sensitivity measurement equipment where voltage fluctuations could compromise data integrity. The unit also excels in field service scenarios, such as on‑site equipment testing or temporary power distribution for construction sites, thanks to its rugged housing and ability to operate on both 50 Hz and 60 Hz mains without reconfiguration. Installation is straightforward: connect the primary leads to the incoming utility source, select the appropriate current rating via the internal tap selector, and terminate the secondary leads to the load. The transformer’s low‑profile design allows it to be mounted on standard DIN rails or secured to a panel using the pre‑drilled mounting holes, making it compatible with existing infrastructure. Proper ventilation is recommended to maintain optimal temperature, especially when operating at the highest current setting for extended periods.

FAQ

What is the difference between buck and boost operation in this transformer?

The buck function steps the voltage down from the primary 245 V to the secondary 220 V, while the boost capability allows the unit to maintain output voltage stability when the input voltage varies below the nominal level. This dual capability ensures that downstream equipment receives consistent power regardless of fluctuations in the supply line.

Can I use this transformer with a three‑phase power source?

Although the transformer is specified as a single‑phase device, it can be connected to a three‑phase system by using one phase and the neutral conductor. For applications requiring three‑phase isolation, Larson offers dedicated three‑phase models that provide balanced loading and enhanced efficiency.

How do I select the appropriate current rating for my application?

Determine the maximum current your load will draw under normal operating conditions. Choose the next higher rating available (22.89 A, 34.33 A, or 68.67 A) to provide a safety margin and reduce thermal stress. The transformer’s internal tap selector allows you to set the desired rating without modifying wiring.

What safety certifications does this transformer have?

The unit complies with UL 60950‑1, IEC 60950‑1, and CSA standards for isolation transformers. It features built‑in surge protection, thermal overload monitoring, and a grounded enclosure to meet stringent safety requirements for industrial and scientific use.

Is custom branding or labeling available?

Yes, Larson Electronics can provide custom branding, labeling, and packaging to align with your company’s specifications. Contact our sales engineering team to discuss options such as logo embossing, color‑coded terminals, and documentation in multiple languages.
