PDD-300 pulsed diode driver
User manual
Warning! This equipment may be dangerous.
Please read user manual before starting operations.
Important note. Please measure output with adequate load only (diodes). Resistive load
connected to the output won’t destroy the driver, but will severe distort its behavior.

Warnings
Warning! The equipment is CLASS I ME EQUIPMENT.
To avoid risk of electrical shock, the equipment must be
protectively grounded.
Warning! There is no user-serviceable parts inside the device.
Do not self-repair the driver. Do not even open the enclosure, because
of electrical shock risk with residual high voltage.
Warning! Equipment is not suitable for use in presence of a
flammable anesthetic mixture with air or with oxygen or nitrous oxide.

Overview / Applications
PDD-300 is a series of high-power pulsed diode drivers. Peak output power is up to 5kW
(with user selectable IMAX and VMAX), averaged output power is up to 300W.
Driver was specially designed for direct diode hair removal application.
Driver’s input is 100-240VAC.
Cooling
The module contains a fan for active cooling. No additional cooling is required.

DESIGNATION
DESCRIPTION
1 (green)
ENABLE
+5V TTL applied to this pin enable PDD.
While 0V are applied to this pin or pin is
unconnected module is disabled.
Once Fault has occurred module is
blocked till you eliminate fault cause, then
disable module and enable it again.
2 (orange)
FAULT
If module is enabled and some trouble has
occurred, module automatically stops
operations and sets Fault status (Fault
loop is “closed”).
Fault can be caused by following
reasons:
- overheating
- mains voltage interruption
- maximum pulse energy exceeded
To remove Fault state one should disable
driver and enable it again
In case of normal operations Fault loop is
“opened”.
Maximum allowed current in Fault loop is
50mA.
3 (transparent)
PULSE 1
+5V TTL pulse should be applied to pin 3
and to pin 8 simultaneously in order to
obtain pulsed current from PDD-300.
In cases if 0V is applied to one of these
pins or at least one of these pins is
unconnected, there will be no current
from PDD-300.

0-10V DC are linear with 0-IMAX.
8 (white)
PULSE 2
+5V TTL pulse should be applied to pin 3
and to pin 8 simultaneously in order to
obtain pulsed current from PDD-300.
In cases if 0V is applied to one of these
pins or at least one of these pins is
unconnected, there will be no current from
PDD-300.

DESCRIPTION
DIODE “+” (red)
To laser diode anode
DIODE “–” (black)
To laser diode cathode
GROUND: M5 stud
Module should be grounded using this stud.
Grounding should be done before powering the system.
Grounding policy
By default OUTPUT POSITIVE and OUTPUT NEGATIVE
are isolated from the chassis’ ground (i.e. output is floating).
Modifications with grounded anode or grounded cathode
are available upon request.

Installation
•Only qualified personnel is allowed install and perform the connection of PDD-300 into
customer’s system
•PDD-300 is intended only for diode driving applications. The module should only be
used inside the medical equipment, which has means to isolate its circuits electrically
from the supply mains on all poles simultaneously
•Use four M4 mounting slits on the bottom side of PDD-300 to fix the module in your
system. Refer to the Dimensional drawing section for their location
•There is no preferred driver orientation, it can be mounted in normal position, upside-
down position or in other orientations, as well
•Connect the module to your system protective ground using provided M5 grounding stud
•Connect AC INPUT, OUTPUT and INTERFACE cables according to their functions
•Since module is air cooled, at least 50mm of free space should be provided both at the
suction and pressure sides of PDD-300
Operations notes
1. The proper sequence of driver's start up procedure is 'power -> enable -> pulse'. Other
sequences are considered as incorrect
2. When driver is powered but disabled, the fan rotates slowly;
once driver is enabled, the fan will accelerate to a higher speed
3. Fault state is set when fault condition is met AND driver is enabled
4. To remove Fault state one should disable driver and enable it again
Troubleshooting
•In case of a mains voltage interruption, the output voltage drops down. Once the mains
voltage is restored, the unit doesn’t restart automatically and needs to be enabled again to
resume the operations.

Pulse width limitations
Maximum pulse width, which the driver is able to provide at its output, isn’t fixed, but depends
on driver’s modification, operating current, load voltage and input voltage.
Approximate formulae to estimate the maximum pulse width in a certain regime is
EMAX=I*V*TMAX, where TMAX is a maximum pulse width PDD-300 is able to provide with
current I and voltage V at its output. EMAX is a maximum extractable energy, which varies from
~200J in standard modifications to ~300J in long pulse modifications.
Examples of pulse width curves for different drivers and different loads are given below. More
detailed information can be requested from the manufacturer.
PDD-300-100A-30V
PDD-300-150A-25V
Maximum pulse width - around 65ms at maximum
current and voltage. Even longer at smaller currents
and/or voltages
Maximum pulse width - around 45ms at maximum
current and voltage. Even longer at smaller currents
and/or voltages
PDD-300-100A-50V
PDD-300-100A-20V
Maximum pulse width - around 35ms at maximum
current and voltage. Even longer at smaller currents
and/or voltages.
Maximum pulse width - around 100ms at maximum
current and voltage. Even longer at smaller currents
and/or voltages.

buffer capacitance of PDD-300 is limited, pulse energy is also limited (E <
EMAX). Please contact the factory for further details.
