LED control gear LCC9 (combined LED dimmer and LED driver in one device) for LED light fixtures and wall boxes. A big step for the installation technology within the field of driving and dimming of LEDs Input voltage 220-240VAC (screw terminal). Designed to fit in a wall box up to two units (2x9W)  or LED fixture Dimming control: - Primary side: push-button retractive/momentary switches - Secondary side: 1-10Vdc controller Dimensions (DxH): dia.57x22mm Housing: thermoplastic, grey colour Max. ambient temperature: +50ºC Weight: 53g Connection wires: 1.5mm² Automatic sensing of which type of control is active - retractive switch, 1-10VDC signal or potentiometer on the secondary side. It is thus possible (on the same unit) to have a retractive switch connected simultaneously on both primary and secondary side. LCC9 automatically detects which control is active. Works also by parallel connection of one or more retractive switches. Soft start Memory function Constant voltage protection Overload protection Over temperature protection Possible cascade connection of LCC9 to dim loads with higher power than 9W. DIP-switch: it can set the type of LED you want to dim and which unit will act as master unit when cascading. Selectable constant currents: 350mA, 500mA, 700mA Selectable constant voltages: 6VDC, 9VDC, 12VDC, 24VDC Standards: EN55015; EN61547; EN61347-1; EN61347-2-13; EN61000-3-2; EN61000-3-3 Insulation class II IP20 Approval: CE/SGS If you choose push button retractive switch/es to control LCC9, functions are as follow: On / Off - A short press. The LED control gear will start with the last used light level (memory function) Dimming up / down - Keep the button pressed until the desired level is reached.
