The UVLO is not adjustable, it is set by the manufacturer to what he considers a safe value for his
selection of components. We have chosen vendors that provide a conservative margin for a more
reliable product. We also want to prevent nuisance dropouts.
As voltage is decreased to UVLO level, the increasing current causes additional voltage drop in the
supply lines. When the UVLO activates, (shuts down the PWM) the voltage will rise again to its no-
load value. To prevent on-off cycling (slow oscillation) based on a sensitive threshold voltage being
crossed by load/no-load conditions, hysteresis is added to the UVLO circuit. The voltage must be
advanced by a considerable margin before the SMPS recovers (turns on) from an UVLO condition,
thus preventing cycling.
The Ballast is rated at 200V-240V and drops out due to UVLO at 165V and recovers at 185V.
The 24V LVS is rated 100V-240V and drops out at 75V and needs 85V to recover.
In the US, we use a 120V line cord to tech a light if we don't need to strike the lamp.
