MK Electric K1521WHILV Logic Plus White Moulded 1 Gang 2 Way Dimmer Switch 40W - 300W
K1521WHILV
Overload Reaction
| Case | Approximate load on the dimmer as a % of its max. rating | Power output to load when dimmer control is set to maximum |
| 1 | Up to 125 | Load will receive maximum power continuously |
| 2 | > 125 to 150 | Output to load will be reduced to 50% of the maximum after a delay of approximately 20 seconds after switch on |
| 3 | > 150 to 200 | Output to load will be reduced to the minimum setting of the dimmer after a delay of approximately 20 seconds after switch on |
| 4 | > 200 | Output will be disabled (load will be switched off) almost instantaneously after switch on |
MK Intelligent Dimmer Switches are not suitable for use with Fluorescent Loads, including Energy Saving Lamps.
• Suitable for dimming Low Voltage Halogen lamps via suitable, fully dimmable electronic or wire-wound transformers.
• Unidirectional current sensing. While being used with wire-wound transformers for low voltage lighting, these dimmer switches continuously monitor the drive conditions to the transformers, which require essentially, bi-directional a.c. supply at their input terminals. If, due to some fault condition, the supply to the wire-wound transformer is detected to be unidirectional, which could result in over-heating and/or damaging the transformer, the dimmer switches' circuitry automatically stops supplying the transformer after a few cycles of detected unidirectional supply.
• Soft Start, which gradually increases the light output from the load over 1 to 3 seconds after switch on. The Soft Start feature is also particularly beneficial when used to dim Mains Voltage Tungsten Halogen lamps which have inherent very high inrush current at switch on.
