DC Converter

The LED-drivers 35/ -70/ -100 DC 24 are equipped with dimming function. They are being used for the power supply of Power LEDs with nominal currents of 350/700/1000mA.

The DC converter has an input voltage range of 12-30V DC. It supplies a maximum output voltage of U_out=0,8 x U_in.

Dimmable devices are available in two designs:

• 1-10V interface

As it is the case with the AC device, the brightness control of the LEDs is also being made via the control logic PWM module with 1-10V control input. Optionally, these control inputs can be operated with an electronic potentiometer (1-10V), a conventional potentiometer or a DC control voltage 1-10V.

• Control input external PWM signal (square)

The brightness control of the LEDs is being made by feeding an external PWM signal in square wave (40Hz ... 10Hz, 3,5 ... 10V) to control input +U_st.

The LED-driver in DC design (12-30V) are available both as housing devices (closed with connection cables) and as open-frame assembly (PCB version).

Connection is being made either via 4 cables or by using clamps on the PCB.
