Thyristor power regulator ТРR3 is intended to control power of active load or active-inductive one in three-phase AC circuits with voltage 220 / 380 V and with frequency 50 Hz.
The power regulator is used in automatic control systems of automatic temperature regulation and other process conditions.
The TPR3 operates together with control devices (of a foreign manufacturer) that have the standard analogue DC output signal.
Basic functions:
- Conversion of DC input signal into AC output capacity;
- Galvanic load circuits’ isolation from signal circuits;
- Overload protection in load circuit;
- Forming of status signal «Overload» (output – open collector);
- Control of phase loss;
- Forming of status signal «Loss» (output – open collector);
- Forming of DC voltage 24 V (for supplying of control device).
