DIMMING REQUIREMENTS

The VLED15 series of drivers operate from either 90VAC to 135 V ac or 176 V ac to 265 V ac, at 47 to 63 Hz. The drivers will operate at

voltages down to 20 V ac for the 120 V versions and 40 V for the 240 V ac versions. The following graph shows the typical output current

versus AC input voltage without a dimmer attached and with a typical LED as the load. Nominal output current shall be achieved at <115 V ac

and <230 V ac when the output voltage is at the nominal of the particular range. When the output voltage is at the maximum value, nominal

current must be achieved at <120 V ac and <240 V ac.
