HPLDD family

New: HPLDD3040

HPLDD3040 laser diode driver

The new HPLDD3040 brings the same control architecture, safety chain, and communications stack to a 30 A platform with 2 mA effective setpoint accuracy.

New product

HPLDD3040 expands the current range
to 30 A

Built on the same protocol, protections, and software workflow as HPLDD1540, the HPLDD3040 is aimed at higher-current laser diode systems while keeping the same compact, integration-friendly form factor.

  • 0–30 A current setpoint
  • 2 mA effective setpoint accuracy
  • Up to 1200 W output power
  • USB, RS-232, and RS-485 support

Meet us in person

Laser-Technica Poland at Ptak Warsaw Expo

12–14 May 2026 • Hall C • Nadarzyn / Warsaw, Poland

We will be showcasing the HPLDD family, discussing integration use cases, and sharing the newest documentation materials. If you are visiting the fair, let us know in advance and we will arrange time for a focused technical conversation.

Product family

Two compact driver platforms, one shared workflow

Both HPLDD models share the same control philosophy, command set, desktop software, and safety architecture. Choose the current range that fits the diode system you are building.

HPLDD1540

HPLDD1540 laser diode driver

Compact 15 A platform for precision CW and gated laser diode control, with 1 mA effective setpoint accuracy and up to 600 W output power.

  • Input voltage10–55 V
  • Output voltage1–40 V
  • Current setpoint0–15 A
  • Output powerUp to 600 W
  • Effective setpoint accuracy1 mA
  • Footprint40 × 60 mm

Quick comparison

Choose the platform that matches the diode system current range

The two models share the same functional architecture and integration points. The main differences are the output current range, effective setpoint accuracy, and board size.
