TunableWhite LED dimmer 12-24 V DC, 2x 1-10 V. Two-channel LED dimmer (single or two-color) for constant voltage operation (12 - 24 V DC). Wiring is via screw terminals. Cable cross-section: 0.5 - 2.5 mm. An external power supply is required for operation. Output signal (dimming): PWM (pulse width modulation). With overload and short-circuit protection, max. output power: 2 x 192 W. The device can use two 1-10 V signals to either dim two independent groups of lights or change the color temperature and dim a TunableWhite group. Socket: without, Material: plastic, Protection type: according to DIN EN 60529: IP20, Protection class: (EN 61140) III, Voltage: 12V 24V, Type of dimming: 1-10 V,
