Relay with phase control (voltage regulators) KIPPRIBOR
Solid-state relays are a class of modern modular semiconductor devices made using hybrid technology, containing powerful power switches on triac, thyristor, or transistor structures. They are successfully used to replace traditional electromagnetic relays, contactors and starters. That is, they use the “ON / OFF” algorithm in their work.
However, in this class there is another type of relay that allows you not only to control the on/off of the load, but also to control the level of the output signal. We are talking about solid-state relays with phase control, in other words, about voltage regulators.
KIPPRIBOR single-phase solid state regulators are designed to continuously regulate the supply voltage of a resistive load in the range from 10V to the nominal value in proportion to the input signal level.
Recommended for simple cases of continuous load voltage regulation. In particular, with the help of these devices, you can adjust the power of heaters, control the level of lighting, etc.
As it becomes clear, the relay data is controlled not by a discrete signal, but by an analog one. KIPPRIBOR voltage regulators are available in three modifications according to the type of control signal:
- HD-xx44.VA [M02] (external resistor resistance control);
- HD-xx22.10U [M02] (control of unified voltage signal 0…10V);
- HD-xx44.LA [M02] (control of a unified current signal 4…20mA).
Comparative table of voltage regulators by type of control signal
| Model TTR | HD-xx44.VA [M02] | HD-xx22.10U [M02] | HD-xx44.LA [M02] |
|---|---|---|---|
| Type of control signal | Variable resistor: 470 kOhm at rated U pit \u003d 220 V, 560 kOhm at nominal U pit = 380 V | Unified voltage signal 0…10 V | Unified current signal 4…20 mA |
| Input impedance | - | ≥ 4 kOhm | ≤ 0.4 kOhm |
| Galvanic isolation from the output circuit | Not | There is | There is |
| Load regulation range | 10…440 VAC | 10…220 VAC | 10…250 VAC |
When operating a relay controlled by a unified voltage signal, it should be borne in mind that the operating range of the control signal is 2 ... 10V. In the absence (break) of the control signal, or if its value is ≤2VDC, a minimum voltage level of ≤10VAC will be present in the load circuit.
