Introduction

Tripp Lite’s S3MT-100KWR480V is a 480V Wrap-Around Transformer that includes two transformers in one enclosure: a 480V (Delta) to 208V (Wye) input isolation step-down transformer and a 208V (Wye) to 480V (Wye) output auto step-up transformer.

The input isolation transformer mitigates utility line surges and spikes, while protecting the UPS. The output auto transformer is designed to support 480V (Wye) IT loads. This model has built-in circuit breakers to prevent dangerous circuit overloads. Eight ball-bearing fans maintain quiet operation and help to dissipate transformer heat. An overheat-sensing relay and switch, combined with an LED light in the front panel, provide over-temperature warning and overheating protection. The UPS system’s small footprint and quiet acoustic profile enable installations with minimal space and noise impact. The transformer features a rugged all-metal housing with a front panel similar to the S3M-Series 208V 3-Phase UPS line.

Isolation Step-Down Transformer

Output Transformer: 208V to 480V Auto Step- Up Transformer

The transformer is extremely heavy. Caution should be taken in moving and positioning equipment. The instructions contained within this manual are important and should be closely followed at all times during installation and follow-up maintenance of the 3-phase transformer and UPS.

CAUTION!
The transformer has a dangerous level of heat. If the transformer’s front- panel red LED indicator is on, the unit’s outlets may have a dangerous level of heat.
All servicing on this equipment must be carried out by qualified Tripp Lite- certified personnel.
Before conducting any maintenance, repair or shipment, first ensure everything is turned off completely and disconnected.

Input and Output Transformer-to-UPS Connection Line Diagram
Connections are shown below for the cabinet with built-in input isolator transformer, output auto transformer and breakers with trip and fault LED.

Input and Output Transformer Connections

WARNING: The input transformer (T-in) output neutral is not bonded to chassis ground. Please provide a means to connect the transformer chassis ground to the transformer output neutral. Note: The transformer chassis ground must be connected to earth ground.
IMPORTANT: You may view and/or download this manual from the tripplite.com website to view the cable connections in colors. Transformer Cabinet
Note: Transformer input is Delta 3-Wire (3Ph + Ground) and output transformer is Wye 4-Wire (3Ph + N + Ground).

Operation

WARNING :
It is not advised to connect two UPS in parallel when using individual transformers for each UPS.

Over-Temperature Protection

Over-Temperature Warning LED Light (Red)
The transformer includes two warning LED lights on the top portion of the front panel: one light for the input transformer and one light for the output transformer. The corresponding warning light may turn ON when the secondary side of the input (T-in) or when primary side of the output (T-out) transformer reaches a temperature of 160°C ± 5°C, i.e. a range of 155°C to 165°C (311°F to 329°F). The warning light turns OFF when the transformer cools to a temperature of 125°C ± 5°C, i.e. a range of 120°C to 130°C (248°F to 266°F).

Over-Temperature Protection Relay and Thermal Switch
The transformer includes two warning LED lights on the top portion of the front panel. One light for the input transformer and one light for the output transformer. The corresponding warning light will turns ON when the secondary side of the input (T-in) or when primary side of the output (T-out) transformer reaches a temperature of 160°C ± 5°C, i.e. a range of 155°C to 165°C (311°F to 329°F). The warning light turns OFF when the transformer cools to a temperature of 125°C ± 5°C, i.e. a range of 120°C to 130°C (248°F to 266°F).

•  Input Transformer (T-in): If the secondary side of the (T-in) input transformer reaches temperatures of 160°C ± 5°C, i.e. a range of 155°C to 165°C (311°F to 329°F), an over-temperature protection relay and thermal switch will activate and will open the breaker on the secondary side of the transformer. Once the transformer temperature has cooled down to 125°C ± 5°C, i.e. a range of 120°C to 130°C (248°F to 266°F) the warning LED light will turn OFF, and you may manually re-activate (close) the output breaker on the transformer to restart normal operation.
• Output Transformer (T-out): If the primary side of the (T-out) output transformer reaches temperatures of 160°C ± 5°C, i.e. a range of 155°C to 165°C (311°F to 329°F), an over-temperature protection relay and thermal switch will activate and will open the breaker on the primary side of the transformer. Once the transformer temperature has cooled down to 125°C ± 5°C, i.e. a range of 120°C to 130°C (248°F to 266°F), the warning LED light will turn OFF, and you may manually re-activate (close) the input breaker on the transformer to restart normal operation.
