ALM221

2 x 25W power supply, constant voltage 24V and configurable constant current
Pulse width modulation (PWM) dimming for perfect LED dimming.
Voltage control of dimming by internal potentiometer, external, 0/5V or 0/10V input.
Temporary dimming by push button; increment or decrement by press.
Temporary dimming by pushbutton also works in PWM mode, and therefore DMX with appropriate interface.
EPWM compatible PWM input and output to drive more powerful power supplies.
Optional module for constant current (ALM025), can deliver a constant voltage channel and a constant current channel.
