LV2 2 Channel 0/1-10V LED Dimming Driver

Model No.: LV2

Overview

Features

2 channel 0/1-10V LED dimming driver, 2 channel PWM constant voltage output.
For dual color control, the two 0/1-10V inputs can be set as warm white and cool white respectively, or one for brightness adjust and the other for color temperature adjust.
0~100% dimming range via logarithmic characteristic provides comfortable human eye experience.
Compatible with active or passive 0-10V, 1-10V dimmers, suitable for LED lighting systems replacing fluorescent lamp dimming systems.

Mechanical Structures and Installations

Physical Layout

The driver features a compact design with clearly labeled connection terminals. Key components include:

Power input terminals (+ and -)
Installation rack for mounting
LED indicator light
SET key for mode switching
0/1-10V input terminals (labeled CCT DIM, GND, CW, WW)
LED output terminals (+ and - for each channel)

Dimensions: 114.00 mm (length) x 38.00 mm (height) x 20.00 mm (width).

Wiring Diagram

The wiring diagram illustrates the connection of the power supply and LED load to the LV2 dimmer driver.

Power Supply Connection: Connect the 12-36VDC constant voltage power supply to the 'Power input +' and 'Power input -' terminals.

LED Output Connection: Connect the positive (+) and negative (-) terminals for the two channels (WW and CW) to the respective LED strips.

0/1-10V Input Connection: The 0/1-10V dimming signal is connected to the '0/1-10V input (DIM/WW)' and '0/1-10V input (CCT/CW)' terminals, along with the 'GND' terminal.

The diagram shows a dual-color LED strip connected to the 'CW' and 'WW' output channels.

Notes

The 0/1-10V input is operable via commercially available simple rotary wall switches designed for 0/1-10V dimming equipment or from dedicated system central dimming controllers.
Compliant with 0-10V, 1-10V, 10V PWM, RX (4 in 1) control signals.
It is recommended that the number of LED drivers connected to a 0/1-10V dimmer does not exceed 50 pieces.
The maximum length of the wires from the dimmer to the LED driver should be no more than 50 meters.

Key Function

The 'SET' key is used to switch between dimming modes:

DIM+CCT Dimming Mode

Press and hold the 'SET' key for 2 seconds; the 'RUN' indicator will flash once.

In this mode: The DIM input controls brightness adjustment, and the CCT input controls color temperature adjustment (factory setting).

WW+CW Dimming Mode

Press and hold the 'SET' key for 5 seconds; the 'RUN' indicator will flash twice.

In this mode: The WW dimming input controls the WW LED channel brightness, and the CW dimming input controls the CW LED channel brightness.

Dimming Curve

0/1-10V Dimming

This graph illustrates the relationship between the 0/1-10V input voltage and the PWM duty cycle (brightness percentage). The curve is logarithmic (Gamma=1.6), providing a smooth and comfortable dimming experience for human eyes.

X-axis: 0/1-10V(V) from 0 to 10.0

Y-axis: PWM duty(%) from 0 to 100%

0/1-10V CCT

This graph shows the relationship between the 0/1-10V input voltage and the Color Temperature (CCT) percentage. The curve is also logarithmic (Gamma=1.6), allowing for precise color temperature adjustment.
