The isolation transformer automatically detects the incoming voltage and will set its input voltage mode according to the below table.
Input voltage range | Green “on” LED | Yellow “115V" LED | Yellow “230V” LED | Behaviour |
|---|---|---|---|---|
0 - 87V | On | Off | Off | Both the input and output are switched off. |
88V - 130V | On | On | Off | Operating in 115V input mode. |
130V - 185V | On | Off | Off | Both the input and output are switched off. |
185V - 250V | On | Off | On | Operating in 230V input mode. |
The isolation transformer has the following LED indications:
LED | Colour | Description |
|---|---|---|
on | Green | Lights when the isolation transformer is operational. |
230V | Yellow | Lights when the isolation transformer is operating in 230Vac input mode. |
115V | Yellow | Lights when the isolation transformer is operating in 115Vac input mode. |
Temperature | Red | Lights when the fan is on. |
The inrush current limiter prevents upstream circuit breakers from tripping when switching on the isolation transformer.
The isolation transformer is fan cooled. The fan speed is temperature-controlled. Its speed (rpm) will increase if the temperature increases.
The isolation transformer is protected against overtemperature and will switch off in case of overheating.
