uniLDD is DC input power converter designed to supply CW or pulsed current for single emitter, bar or stacked laser diode in Constant Current Mode (or CC mode). It can be installed either as unit assembled either as set of open PCB boards or as standalone unit. The standalone unit is uniLDD enclosed together with the power supply. |

Analog Control Signals
Description of Analog interface pinout
Connector type: 15 pin D-SUB female
| Pin | Signal name | Direction | Voltage level | Description |
|---|---|---|---|---|
| 1 | Enable | Input | TTL, LVTTL | The enable function pulls the RTO signal high |
| 2 | Ready to Operate (RTO) | Input/Output through 330 Ω resistor |
>2.4 V driver output is active, <0.5 V output is clamped |
RTO is tied to “High” by the driver when “Enable” input is High. Alarms clamp RTO low and disable driver output. External device may clamp RTO to GND and disable driver output. RTO allows to join fault circuits of several drivers connected in parallel |
| 3 | Interlock | Input | 10 kΩ pull up to 3.3 V, LOW ≤ 0.4 V |
The Interlock function can be connected to external safety or machine protection switches such as door or temperature switches. Open = OFF Connect to GND = RUN |
| 4 | GND | – | – | – |
| 5 | Vout monitor | Output | Vout, driver output voltage | The output voltage monitor. Vout = Diode compliance voltage + voltage drop on connection wires |
| 6 | Iout monitor | Output | 0 – 12 V 1) = 0 – Iout max | The output current monitor |
| 7 | Iprogram | Input | 0 – 9 V 1) = 0 – Iout max | Output current setting or modulating by applying a voltage, CW and Pulse mode |
