DC power supply for HPP
The HPP can be driven by any DC power source without current foldback.
When the HPP in on, it will draw high current from the DC source which should send
continuous limited current to the HPP and should not fold back because the HPP needs
certain input voltage to operate.
It is recommended to use a LDD-3000 or LDD-6000 with a HP option to drive the HPP.
The LDD-3000/6000-xx-yy-HP is configured to run with the HPP. Output voltage can be
set to match the laser load and output current can be set to meet the max average load
current.
Besides, the LDD-3000/6000-xx-yy-HP interfaces with the HPP to regulate the output
voltage to perfectly match the load voltage for the highest efficiency and least heat
dissipation inside the HPP.
For lower average power a LDN-2000 series power supply can be used with the VP
option. This power supply does not have the HP feedback to automatically adjust the
output voltage to the HPP demand. However, this version has a voltage adjust control
input on pin 2 of the control interface to allow the user to match the LDN output voltage
to the HPP load requirements.
