126421 Operation Mode

• Light regulation 0/1 – 100 % by means of PUSH function, 0/1…10 V local interface (I=0,35 mA) or 100 Kohm potentiometer.
• (4) Default dimming AM+PWM: 1-25% PWM 2 kHz+25-100% AM.
• (4) Full PWM dimming (240 Hz- 1-100%) and Constant Voltage 12/24V available by removing JP3 on the driver. Enable JP3 to switch to AM+PWM.
• (5) Full AM DIMMING: 1-100%.

• Light regulation 0/1 – 100 % by mains of PUSH function (L mains voltage: 170 Kohm):
– a short push to turn on and off;
– a longer push to increase or decrease light intensity;
– regulation automatically stops at minimum and maximum values;
– for another on, regulation or off command, release the push button and give the desired command again;
– dimming level memory at mains restore.
• Maximum length of the cable, from push button to last driver, must be max. 15 m / 49 ft. In case of applications where the cable is longer than 15 m / 49 ft, keep this separate from the 110 – 240 Volt mains cable.

• ATTENTION: only use normally open push buttons with no incorporated warning light.
• Specific dimming terminal connection with a 0/1…10 Vdc electronic potentiometer (0/1…10 V local dimming, double insulation required for external connection).
• Max. 10 synchronised drivers of which only one can be controlled (1 Master + 9 Slaves of any JOLLY Series). Only for full PWM dimming (4).
• Synchronization cable supplied separately.
• Regulation is possible by means of DALI and DMX coupled with DALI/DMX INTERFACE.

Compact multi-current 1-10V LED drivers are versatile, space-saving power supplies that allow installers to select exact output currents (using built-in DIP switches) to match specific LED fixtures. They translate standard 1-10V analogue signals to smoothly and accurately dim connected LEDs, typically from 10% to 100% or down to 0% brightness.

Core Features

Multi-Current Selectability: Feature physical or digital DIP switches allowing you to toggle the driver to various constant current (mA) settings (e.g.350mA, 500mA & 700mA) to support different luminaires.

Ultra-Compact Footprint: Engineered for tight installations, such as slim ceiling voids, small junction boxes, or tight recesses.

1-10V Analogue Dimming: Uses a low-voltage, wired 2-core control pair. A 1V signal equates to minimum brightness, while a 10V signal delivers full 100% output.

How They Work

These drivers operate via Constant Current (CC), providing a fixed electrical current required by LEDs while letting the voltage fluctuate to maintain a stable light output.

Wiring: LEDs must be wired strictly in series so that the exact same current passes through each module.

Dimming Signal: The 1-10V dimmer switch sends an analogue signal which dictates the output. The drivers often support “3-in-1” dimming, meaning they can also respond to variable resistance (potentiometers) or PWM signals.

Control Capacity: You can often wire up to 40 individual drivers to a single 1-10V dimmer, as the control circuit only draws a minute amount of current.
