The EUP20A-1HMC-1 is a 20W constant current LED driver from Euchips, built for indoor LED lighting where 1-10V dimming control is needed. Output current is selected via a DIP switch, so one driver can cover several fitting types on a single project.

Key features

• Dimming control: 0/1-10V active signal, PWM signal, or adjustable resistance
• Dimming range: 0.1% to 100%, down to off, with linear proportional response and no flicker
• Output current options: 350mA/9-40VDC/14W, 500mA/9-40VDC/20W, 550mA/9-36VDC/19.8W, 700mA/9-28VDC/19.6W, selectable by DIP switch
• Input voltage: 220V to 240V AC, 50/60Hz
• Efficiency: up to 85%, with built-in active PFC
• Operating temperature: -20°C to 50°C

Applications

Suited to downlights, panel lights, spotlights, ceiling lights, decorative lights, floor lights and flood lights. It runs at 100% output when no dimming signal is connected, so it also works as a standard constant current supply on jobs where dimming isn't required.

Build and protection

Housed in a PC enclosure measuring 150 x 43 x 29mm. Protection is included against short circuit and overload, and Euchips backs the EUP20A-1HMC-1 with a 3 year warranty.
