Regulátor výkonu KEMO M204 230 V, max. 16 A pre ohrievače

• The Kemo M204 is a 230 V power controller with max. 16 A for heaters.
• Control with pulses at zero crossing
• incl. potentiometer
• Operating indicator with built-in LED

It controls resistive loads such as heaters etc. with pulses at zero crossing without additional interference suppression. The control is achieved by switching on and off in pulses. Therefore only suitable for heaters (heating plates, welding wires, thermal welding machines, ovens etc.). Not for motors and lamps, these would stutter or blink.

• Features
• Aluminium metal housing with cooling fins, potted
• The potentiometer is fully insulated on the operator side
• Circuit description

The module switches the heater on and off depending on the position of the potentiometer, always at phase zero crossing. The switching frequency is approx. 0.8 Hz. The length of the on phases depends on the position of the control potentiometer. Control position left: long on phases and higher heating power.

The module can heat up during operation depending on the load. It must therefore be installed in a well-ventilated place. If the metal housing of the module heats up to over 60°C, it must either be screwed onto an additional heat sink or blown with a small fan. In well-ventilated normal operation up to 1000 W this should not be necessary. The module may only be installed by a qualified person (e.g. electrician) in compliance with VDE safety regulations. It is essential to ensure that touching the live contacts with fingers is impossible. The potentiometer is fully insulated on the operating shaft and mounting thread. The installation must be such that only the insulated operating shaft can be touched and not the electrical connection pins. In addition, a fuse must be connected upstream according to the drawing. The cables to the module must be secured against unintentional pulling out (strain relief).
