The DALCNET DLD1248-1CV is a single-channel LED dimmer, fader, and driver in a DIN-rail 2-module package.

It supports an input voltage of 12-48V DC and has a constant voltage output with Digital PWM (D-PWM), which supports a peak load of 8A. The D-PWM frequency is adjustable, with a choice of 300, 600, or 1200 Hz. The output curve is also adjustable, with the options of linear, quadratic, or exponential. In addition, it features soft start and soft stop.

The DLD1248 has multiple options for controlling it: a N.O. push button, a potentiometer, or a 0-10V or 1-10V control signal. It supports a minimum brightness level of 0.1% when using a control signal or potentiometer and 1% when using a push button. Even when using a push button, you still have control over the brightness level, thanks to the button being able to perform multiple functions:

• Click: On/Off
• Double Click: Maximum intensity
• Long press from Off: Turn on at 1%
• Long press from On: Dimmer up/down

The DALCNET DLD1248-1CV can operate in an extended temperature range of 14 - 140 °F (-10 to 60 °C). It also has many electrical and thermal protective measures:

• OTP: Over-temperature protection on the output channel
• SCP: Short circuit protection
• CLP: Current limit protection
