| Control Options |
|
|
|
|
| POSITIVE ENABLE ** (white/red wire) - Connect lead to positive to turn unit on. Open to turn unit off. |
|
– |
|
10 |
| TTL LEVEL INHIBIT** (white/violet wire) - Open lead or connect to positive to turn unit on. Connect to return to turn unit off. Can be controlled by TTL circuitry with proper interfacing. |
– |
13 |
| TTL LEVEL ENABLE (yellow wire) - Connect lead to return to turn unit on. Open to turn unit off (not compatible with option 16). Can be controlled by TTL circuitry with proper interfacing. |
– |
14 |
| ENABLE/FLASHER - Connect red wire to +5VDC and black wire to return. Connect white/orange wire to return to turn unit on. Connect lead to +5VDC to turn unit off (approximately 10µA leakage during shutdown). Or open lead to cycle unit on and off at factory preset rate. |
H |
16 |
| LOW CURRENT DRAIN STANDBY ENABLE** (white/yellow wire) - <5µA. Connect lead to positive to turn unit on. Open to turn unit off. |
– |
17 |
TTL LEVEL CONTROL - With white/red wire connected to +5VDC, connect white/black wire to return to turn unit on. Open to turn unit off (not compatible with option H). Can be controlled by TTL circuitry with proper interfacing. Control circuitry requires 10mA minimum.

| Operating Options |
|
|
|
|
| INPUT FILTER (choke) - Can dramatically reduce conducted emissions from the switching section of the power supply. |
|
– |
|
37 |
| ACTIVE FILTER (low ripple) - For models not currently available, this option can be engineered to a customer’s specific needs. May result in a larger case size. Reduction in ripple will depend on the laser tube used, power rating of the power supply, and size restraints of the total package. |
A |
38 |
| SHUNT DIODE - For lower battery drain, the series reverse polarity protection diode may be changed to a shunt diode. Can increase efficiency up to 5%. A slow-blown fuse—3 amp for L23 and 2 amp for L28 series—should be used on the positive lead to protect the power supply from incorrect connection. |
– |
39 |
| INCREASED STARTING VOLTAGE** - Increases capability of the power supply 20 to 50% higher than what is specified. |
J |
42 |
| BALLAST MODULE** - Typically an 82kΩ, 7W resistor encapsulated in a tube 0.42” in diameter and 2.0” long. Ballast must be less than three inches from the anode of the tube. Maximum power that can be dissipated in each module is 3.5W. |
L |
43 |
| NEGATIVE HIGH VOLTAGE OUTPUT** - High voltage lead becomes a black 20kV lead. |
M |
44 |
| CDRH DELAY (violet wire loop) - For customers requiring a 3- to 5-second delay in the start of the laser tube after power has been applied to the power supply. Delay can be disabled by cutting the 1.5” loop. |

46 |
| EMI SHIELDING** - Contact us for more detailed information. |
S |
47 |
| AUXILIARY OUTPUT** - Contact us for more detailed information. |
Y |
– |
| INCREASED LINE VOLTAGE** - Input nominal voltage can go up to 50% higher than the specified nominal with a ±10% line change capability. |
– |
52 |
| DECREASED LINE VOLTAGE** - Input nominal voltage can go down to 25% lower than the specified nominal with a ±10% line change capability. |
F |
53 |
| BLEEDER RESISTOR - 100MΩ resister on output. |
W |
60 |
| OPEN CIRCUIT SHUTDOWN - If laser tube does not start within one second of the time voltage is applied, power supply will shut down and must have the input voltage removed to reset the latch circuit. |
V |
61 |
HIGH TEMPERATURE** - Enables the power supply to operate in ambient temperatures up to 80ºC.

| Calibration Options |
|
|
|
|
| CURRENT ADJUST, EXTERNAL (orange wires) - Available with a maximum adjustment range of ±30% from a nominal point, limited by the operating capability of the model. Adjustment may be achieved in one of two ways: by using a 2kΩ potentiometer or by using a factory dual or triple calibration. Potentiometer - 10” leads. Triple calibration - 10” leads. Dual calibration - 1.5” lead loop. Please specify type of external current adjustment required. |
|
C |
|
22 |
CURRENT ADJUST, INTERNAL - Available with a maximum adjustment range of ±30% from a nominal point, limited by the operating capability of the model.

| Physical Options |
|
|
|
|
| REVERSE WIRE EXIT - Switches the end of the power supply by which the input/output wires exit. |
|
P |
|
30 |
| END MOUNTING HEATSINK** - Allows mounting holes to exit end of unit. Input/output wires exit end of heatsink. |
– |
31 |
| OPPOSITE WIRE EXIT - Input/output wires exit opposite ends from each other. |
