Step-Down Transformer for 120V Output

The Vertiv Liebert TDU-4000RTL630 converts 208VAC or 240VAC input to 120VAC output for compatible UPS systems. It supports 200, 220 and 230VAC nominal inputs. This 2U rack-tower unit includes a mounting kit and forced airflow cooling.

Input Range and Efficiency Limits

The unit accepts 208VAC or 240VAC sources with a 200 to 240VAC tolerance band. AC-AC efficiency reaches 94 percent under load. It is designed for single-phase UPS products that only accept 208VAC input and require 120VAC distribution.

Capacity and Connection Headroom

Rated at 4000VA and 4000W, the TDU provides ten output receptacles: eight NEMA 5-15/20R and two NEMA L5-20R. It pairs with 5kVA and 6kVA Liebert UPS models such as the GXT3-6000RTL630 and PSI5-5000RT208. Loads exceeding 4000W will overload the transformer.

Questions about this item

Which output connections does the 4000VA model provide?

The unit supplies 10 output connections: 8 NEMA 5-15/20R and 2 NEMA L5-20R.

What does the 94% AC-AC efficiency mean for daily operation?

Only 6% of input power is lost as heat, so the transformer runs cooler and reduces electricity cost.

What input voltages does the 208/240V step-down accept?

It accepts 200, 208, 220, 230 and 240 VAC input and converts to 120 VAC output.
