LDD-100/150/250-XX-YY
CW Diode Driver Power Supplies
The LDD-100/150/250 family of high power CW diode laser can be configured for
output currents from as low as 10A to output current up to 80A at maximum
power levels from 100W to 250W.
As a laser diode driver, the LDD diode driver acts as a programmable current
source and delivers constant current based on the input program signal,
Iprogram(+), which is normally 0-10V. All units are configured with a maximum
current and maximum voltage capability, depending on the user's requirements.
LDD power supplies will deliver current, as programmed, into any load, providing
the voltage requirements of that load do not exceed the maximum rated voltage
of the unit. When the required compliance voltage is higher then the maximum
rated output voltage of the unit, the unit will limit output current.
LDD diode drivers utilize a proprietary low loss, high frequency power factor
correction circuit which keeps power factor above 0.98. Power factor corrected
power supplies use up to 30% less input current and meet stringent IEC
harmonic requirements. The output inverter is a state-of-the-art zero voltage
switching (ZVS) inverter which permits very high frequency power conversion
with minimum losses and electromagnetic noise.

AC Input Power Circuitry AC input power is processed through a line filter to reduce the conducted EMI to an acceptable level. The LDD-100/150/250 line filter has minimum capacitance to ground to minimize leakage currents. Earth Ground stud is provided near the AC input terminals and should be connected to the system ground. - Page 4 All internal power supply requirements as well as the external +/-15V and +5V power supplies are derived from the power factor control boost inductor.
