2. Operation
2.1 Package Content
•Requested COBe driver.
•Power source: input 100 - 240 V~, 50 - 60 Hz; output 18 V, 2 A;
99 x50 x33 cm, cord length 1.5 m.
•Power cord 1.85 m long
•Connector cable
•User’s manual
Inspect carefully the devices and make sure there is no damage.On the contrary, do
repair or replacement information.
2.2 Before use
Connect the LEDe module to the COBe. Insert the plug of the power cord into the
power supply and connect the power cord to the power outlet. Then, introduce the
plug of the power supply into the light source power input (DC female type).
The COBe is designed to have intensity control in continuous and modulation
modes. The easy user interface permits to select the desired mode (see section 2.3).

2.4 Operation Modes
COBe LED drivers are intended for operation with LEDe modules. The utilization of
LEDe modules with COBe LED driver requires the prior connection of a cable (included
with COBe driver) between the COBe LED driver (7) and the LEDe module (8).
The controls feature a three way switch (3) to select the operation mode: continuous,
pulsed or off. A second control (1) is used to manually adjust the drive current in
continuous mode. A connector allows (4) to introduce a control signal in the PWM
mode.
•OFF mode
The switch (3) on the right of the frontal face of the LED driver has to be on the
middle position (‘OFF’).It is suggested to have the switch in this position when
connecting the power supply to the light source through (5).
•CW mode
To select the continuous mode, please move the switch (3) to the left position (‘ON’).
In this mode, the left knob (1) controls the LEDe module intensity. The intensity can be
adjusted between 20% (fully counter-clockwise) and 100% (fully clockwise) of
maximum intensity.
•PULSED mode
To work in pulsed mode, please move the switch (3) to the right position (pulsed
signal drawing). In this mode, the LEDe module intensity can be adjusted between 0%
and 100%of maximum intensity changing the duty cycle of the PWM signal introduced
through the PWM input connector (4) of SMA female type.
The PWM signal must vary between 0 and 5 V. Voltages out of this range can
damage the PWM input and disable the PWM mode. Voltages below 1.5 V will be
recognized as low level while tensions above 2.8 V will be considered high level. A
pulsed frequency of 500 Hz or lower is recommended to achieve the maximum
resolution. However, higher frequencies, up to 100 kHz, can also be used.
Whenever the LED driver is on, either in CW mode or in pulsed mode; the green LED
indicator (2) located on the front face of the light source will be on.In case of being in
pulsed mode, the LED indicator will blink in the same way as the light source.

3. Important Notes
Before operation
•Do not remove or alter any installed safety device on this equipment. Doing so will
cancel your warranty and create an unsafe operating environment.
•There are NO user serviceable parts inside. Dangerous currents are present in this
device. Only allow qualified personnel to service this unit.
•Inspect this unit and its power supply before using it for the first time. Do not use the
unit if it is damaged in any way. Contact us for repair or replacement information.
During operation
•Do not cover the source or obstruct the air flow for its refrigeration. Avoid exposure to
direct sun light. A rise in the light source’s temperature could affect its operation or even
damage its components.
•The equipment should not be used adjacent to or stacked with other equipment. If
adjacent or stacked use is necessary, the equipment should be observed to verify
normal operation in the configuration in which it will be used.

Electromagnetic Compatibility
•Portable RF communications equipment (including peripherals such as antenna cables
and external antennas) should be used no closer than 30 cm (12 inches) to any part of
this equipment. Otherwise, degradation of the performance of this equipment could
result.
•The use of cables, power supplies, transformers and accessories other than those
specified by Pyroistech S.L., in addition to not being covered by the warranty, may lead
to increased emissions and/or decreased electromagnetic compatibility.
4. Warranty
Pyroistech’s general warranty for a product has a 1 year duration.
This warranty includes repairs and replacement of damaged parts due to a malfunction
of the COBe LED driver, as long as said malfunction can be attributed to errors made in
the manufacture of it by Pyroistech SL, not to a punctual misuse of the source or to a
continued incorrect employment of it by the user, whether conscious or unconscious,
due to not having followed the operation recommendations indicated by Pyroistech SL
There is the possibility of extending this guarantee. For more information, contact
Pyroistech S.L.
