Controlador de potencia con sensor Kemo M156, 230 V/CA, 1 kW, regulador para cargas resistivas e inductivas

The Kemo sensor power controller is an electronic control module for power control of suitable resistive and inductive loads with 220–240 V/AC.

• For suitable resistive and inductive loads with 220–240 V/AC
• Load capacity up to max. 6 A
• Operation optionally via push-button switch or sensor contact
• Via an external push-button switch or a touch-sensitive sensor contact, the power can be continuously varied as well as switched on and off. This makes the module suitable, for example, for brightness control of incandescent lamps or for power control of suitable electric motors and electromagnets.
• Power control via push-button or sensor contact
• Continuous power adjustment by longer pressing
• Short tap to switch on and off
• Last power setting is retained when switched off
• Automatic ramping up and down within about 5–9 seconds
• Also usable as a light dimmer for suitable lighting applications
• At powers above 500 W, additional cooling is required
• Continuous control with memory function

When switched on, the supply voltage is initially present at the module while the connected load remains switched off. When the connected push-button is pressed or the sensor contact is touched, the M156 continuously increases or decreases the output power. For an incandescent lamp, this corresponds, for example, to a slow brightening or dimming. When operation is stopped at the desired point, the achieved setting is retained. A short tap then switches the load off. After another short press, the previously selected setting is reactivated. The module can thus be used not only for continuous power adjustment but also for convenient switching on and off. For suitable lighting applications, the controller can also be used as a light dimmer. According to the manufacturer, a complete control cycle from bottom to top and back takes about 5–9 seconds.

• Phase-angle control for suitable loads

Within each AC half-wave, it is controlled how much electrical power is transferred to the connected load. This allows, for example, classic incandescent lamps to be influenced in their brightness or suitable motors in their power. Decisive is the suitability of the load. Resistive loads as well as electric motors and other inductive loads whose power can be controlled via phase-angle control may be connected. Not all electrical devices meet this requirement. In particular, energy-saving lamps, lamps with upstream electronics such as electronic halogen transformers, and motors with starting capacitors must not be connected according to the instructions. For motors, some drives may not start automatically after being ramped down and then switched on again because of the required starting torque.

• Sensor or push-button operation

Two connection variants are available for operation. In addition to a standard push-button switch, a bare metal part can be used as a sensor contact, for example a screw with a larger head. This is mounted insulated and connected to the designated sensor connection of the module. The connecting cable to the push-button or sensor may be a maximum of 10 cm long. For longer cable lengths, a shielded cable must be used and the shield connected to the "Phase" terminal on the module. The background is the possible influence on the sensor function by external electric or magnetic fields. Push-button switch or sensor contact are not included in the stated scope of delivery.

• Load capacity, cooling and installation

The maximum current load capacity of the M156 is 6 A. The fundamentally connectable load is up to about 1380 W. At the same time, the inrush current of the respective load must be considered. For large individual loads, for example a 1000 W halogen spotlight, the module should therefore not be loaded with more than 1000 W. During operation, the control module heats up depending on the connected load. It must therefore be mounted in a well-ventilated location. At loads above 500 W, additional cooling is required. For this, the module is attached via its cooling bracket to a well-ventilated, insulated metal part or heat sink with at least 100 × 50 × 3 mm. The electrical connection must be made in accordance with the relevant VDE safety regulations. These include in particular protection against contact, upstream fuse protection and fire protection.
