Phase transformer, depending on the model has a ratio of 220 V. to 22/38 V. or 380 V. a 22/38 V, with an apparent power of 300 VA. It is required for obtaining a low-power three-phase system, supplying the RNC/RTC-120 modules.
- Selection of 22/38 V output voltage by selector switch.
- Successive phase indicator light.
- Overload and over-voltage protection.
- Requires ALI-700 ±15 V power supply module and table-mounted frame.
