LED Power Supplies
150W
Constant Voltage /Current
LDB Series
FEATURES
? Universal Input: 90-305VAC
? Constant Voltage/Current
? High Efficiency 92%
The LDB150 series of constant voltage/current LED power supplies
can deliver up to 150W output power in an extremely compact
package size.
The LDB150 can deliver constant voltage single outputs 24V and 48V
outputs in a compact package. At only 35mm high, the LDB150 offers the
lowest profile LED driver solution. Furthermore, the LDB150 can operate as
a constant current driver delivering the maximum output current range over
the defined voltage range.
? IP67 rated
? Power Factor: Typical 0.95
? OCP, OVP, SCP, OTP
? -30 to 70°C deg operation (4)
? 5 Year Warranty
