P12 Digital display inteligent laser power supply for reci w2 tube
P12 Power Supply Instruction
Wide Input Range (90v~250v): it equals to put a voltage regulator
and stabilizer in power supply, which can be used under different
input voltages in different countries or outputs stable current under instable input voltage.
Short Circuit Protection: when positive and negative poles
short~circuits, power supply will cut off the circuit automatically
Open Circuit Protection: when positive and negative poles
open~circuits, power supply will cut off the circuit automatically
Input Enable Signal Detection: show electrical signal from
machine’s control board
Temperature/Humidity Detection: self~protection starts when
temperature or humidity is over permit value to ensure the safety
of laser operation
Working Status Detection: monitor electrical signal from laser tube
in time and analyze its working status
Malfunction analysis: analyze disorders by machines/ laser tubes
and show that information on screen in different languages
NOTICE: Please deal with the malfunction according to the given
solutions showing in screen firstly. Power supply can be used again
only if it is powered off and restarted.
3. Wiring instructions
1 Footer 1 is 5V power supply. (Not needed when connecting the
cardinal plate. It is used when regulating the power with
potentiometer and the 5V current should be less than 20 mA.
2 TH. TL refers to high and low power level respectively, and WP
refers to water protection.
3 Footer 5 G refers to ground, and 6 refers to input end.
4 When connecting the control plate, connect the light signal with
footer 2 in the case of high power level light~emitting, (footer 3
for low power level light~emitting), connect the ground~wire with
footer 5, connect footer 6 with power control analog signal, and
make short circuit for footer 4 and 5.
5 For testing: 3, 4 and 5 are in short circuit (or 4, 5 are in short
circuit and 3, 5 are connected to switch), the potentiometer center
is connected with 6 IN, and the two other ends are connected to 5V
and ground (1 and 5) respectively.
6 PWM can also be used in footer 6, but the pulse peak is required to
reach 5V, and the frequency should be above 20K. When the pulse
peak signal can't reach 5V, please rotate the current regulator
button clockwise for adjustment.
7 The high power level controls the light, 1 and 2 are connected, and
4 and 5 a
