Power control circuitPower control is used for different purposes. For example, to extend lamp life. They are still used everywhere, because of their price and availability. The device is installed between the power wire and the lamp, the voltage is set at 70%. Service life is increased several times.

When a transformer in which household windings with different voltages fail, both of them fail in a household appliance. And with the use of a triac power control by putting half the voltage, we get a living detail.

Bought a home appliance abroad, and it is designed to work on a voltage of 110 V? And here again power control will helpby putting half the voltage. With a load of up to 250 W, the device is not equipped with a radiator.

Circuit of the triac power control

Power control circuit One more variant of the classical circuit, assembled on the VS1 Triac (TIC226M), VD3 dinistor (32 V). Capacitor C1 is charged with each voltage wave that passes through resistors R3, R2. When the level reaches 32 V, the capacitor C1 transfers the accumulated charge to the VD3 dynistor via the resistor R4. The power at connector X1, depends on the operating time of the simistra. The moment of activation is determined by the voltage on C1. The greater the resistance value on the resistor R2, the longer it will be in the closed state. These ratings provide adjustment at full power range.

To achieve smoothness, use R2 resistor of group b. Diodes VD2, VD1 and a resistor ensure smooth operation at minimum power. Without such an add-on, the adjustment will be with dips (the lamp brightness will increase from 0 immediately to 5%). When the voltage on C1 does not exceed 30 V, and on R2 there is a large resistance, then the drive is in the closed position and the power is 0.

Resistor R4, sets a limit on the maximum current passing through the dynistor to 0.1 A. This increases the duration of the pulse required to run VS1.

REGIN PULSER

Triac regulator PULSER is used to adjust electric heaters (single phase and two phase). Mounted on a vertical surface, connected in series between the device and the power supply network. PULSER is equipped with an input for a temperature sensor and a temperature controller.

Control is carried out by switching the heater on and off on a proportional basis (30 seconds running, 30 seconds off). So, energy is saved, and the temperature in the room remains at the same level. The load distribution is performed by a triac (semiconductor device). This provides additional reliability. due to lack of mechanical elements. Switching is performed at zero voltage, this prevents the formation of electromagnetic interference.

If the temperature in the room changes rapidly, then the regulator begins to work in a special mode, with a return point to the initial parameters after 6 minutes. At night, you can set a special temperature. With excessive power of the electric heater, the load is divided into several devices with control from a single regulator.

REGIN PULSER / D

Triac power regulator PULSER / D is used to adjust the electric heater.

The model is intended for DIN rail mounting. The maximum power of 3.6 kW (at 230 V), 6.4 kW (at 400 V). Automatic switching between proportional-integral and proportional regulation. On the PULSER / D there is a connector for a temperature sensor, which is placed in the room or duct.

Temperature control is carried out by switching on and off the electric heater at specified intervals of time. What provides energy savings while maintaining the temperature at a comfortable level. The settings are made by a sinist, made without mechanical elements, to increase reliability. Switching on and off occurs at zero voltage.

When the temperature in the room changes rapidly, the regulator switches to a proportional-integral mode with a fixed time and zone. The transition to the standard settings is carried out in 6 minutes. When the ambient temperature changes slowly, proportional operation is used. The clock mechanism allows you to adjust the night mode.

REGIN TTS

Technical parameters of the regulatorRegulator for a three-phase electric heater controlled by thermal sensors. There is a function of maximum and minimum temperature. Designed for installation in a cabinet or wall. Available in 3 varieties for networks of 500 V, 400 V, 230 V. When the voltage is more than 25 A, you need to install the TT-SLAV add-on. The total load will be distributed to both devices and will not exceed 50%.

With constant switching on and a load of 100% for 2 minutes, the device switches to standard operation and maintains the set temperature. With a gradual decrease in power as needed. The device independently switches on and off the heating system as needed.

The slave TT-MSLAV detects the load on the TTC and turns on or off the additional heating. When loading by 90% the device increases power by 1 step. Similarly, a decline occurs. For normal operation, the power should not exceed 70% at each stage. To ensure smooth operation, switching between stages occurs with a delay of 5 minutes.

Wiring diagram

Power regulatorsThe regulator is connected to a three-phase heater with a symmetrical load. The supply phases are connected to the terminals. Grounding is fastened with a screw. Power is supplied through the temperature switch of the heater and air sensor.

If the capacity of the heating system exceeds the regulator’s capacity, then use 2 or more devices. Everyone must be connected to their load. The temperature sensor is connected to the main one, and the blocks are interconnected by terminals.

An optional TT-SLAV node is connected to the front panel of the TTC. Labeled wires are attached to the first and last terminals. For safety, the power supply is connected through a fuse. The total load should not exceed 45%, otherwise the device will work unstable.

When connecting TT-MSLAV, the first stage should not be more than 70% of the TTC power, and the second, 2 times more, the third - in 4. For example, with total indicators of 85 kW, TTC accounts for 14 kW, the first stage - 10 kW, the second - 20 kW, the third - 40 kW.

Sensor installation requires the second switch to be switched to the “On” position. Maximum and minimum temperature mode only works. in the presence of temperature sensors REGIN. Which is installed in the duct and transmits readings to the terminals. When installing the TK-K330 model, the 0 ° C position corresponds to the full rotation of the switch counterclockwise, the end position is 30 ° C, the average is 15 ° C.

When connecting an external control signal to the TTC model, 1–4 switches should be in the “OFF” position. An external signal is connected to terminals 1 and 5.

To activate the low temperature mode during the night, it is necessary to close the relay between 1 and 2 terminals. A REGIN thermal sensor is required for operation.

Simistor power regulator, everywhere used in home appliances. In the household will help extend the life of the incandescent bulb, reanimates the failed transformer, cuts the voltage for appliances designed for 110 V. The design of the regulator is quite simple and, if there are parts, it is easy to assemble it yourself. And if there is no desire and opportunity, buy a ready-made solution, which are numerous on the market.
