Vertiv Liebert TDU 2U Rack Mount Stepdown Transformer L6-20 Input (8) 5-15/20R (2) - TDU-3500RTL620

Vertiv TDU-3500RTL620 Stepdown Transformer

Overview

The Vertiv Liebert TDU-3500RTL620 is a 2U rackmount stepdown transformer designed to convert higher input voltages (208/240 VAC) down to standard 120 VAC for equipment in data closets or server racks. This unit is essential when your power distribution units (PDUs) or sensitive IT gear require 120V but the facility's primary power is 208V or 240V. It provides a stable 120 VAC output with a substantial 3440W capacity, suitable for powering multiple devices or higher-draw equipment.

Compatibility

This transformer accepts input voltages of 208 VAC or 240 VAC, with acceptable ranges including 200/220/230 VAC. It delivers a regulated 120 VAC output, compatible with standard 120V equipment and PDUs that accept 5-15R or 5-20R outlets. The input connection utilizes an L6-20P plug, common in higher-voltage IT power infrastructure.

Installation Notes

Install this unit in a standard 19-inch rack, occupying 2U of vertical space. Ensure the input circuit breaker or power source can support the transformer's load capacity. The operating temperature range is 32° to 104° F (0° to 40° C), making it suitable for standard climate-controlled IT environments. Its 94% efficiency rating minimizes wasted energy as heat.
