The Newport N3120-6DS EOS Driver Module is a precision current source designed for driving laser diodes and electro-optical devices within modular controller systems. It delivers stable, adjustable current output with multiple layers of protection and operates in both normal and continuous wave (CW) modes via manual level adjustment.
Technical Specifications
The N3120-6DS functions as an independent driver module within Newport’s multi-channel modular laser diode controller mainframes. Each channel operates with its own independent power supply, enabling simultaneous control of current and temperature across up to 16 independent channels. The module incorporates adjustable current limits paired with redundant hardware current limits to prevent overcurrent conditions.
– Key Features
• Manual level adjustment for current control
• Normal and CW (Continuous Wave) operational modes
• Power-on indicator LED
• Adjustable and redundant hardware current limits
• Slow start circuitry for transient protection
• Output shorting relays for laser diode protection
• Independent power supply per channel
The multi-layer protection architecture integrates slow start circuitry, transient protection, and output shorting relays to safeguard connected laser diodes against overcurrent and transient events.
– Typical Applications
The N3120-6DS serves applications requiring precise current control for laser diodes and electro-optical devices in scientific research, industrial automation, and photonics environments where stable, accurate current sourcing is critical.
– Compatibility & Integration
The N3120-6DS is part of the Newport N312 Series of EOS Driver Modules and integrates into Newport’s modular laser diode controller mainframes, which accommodate various driver, TEC temperature control, and controller module combinations in space-saving, rack-mountable instruments. Remote operation is supported via IEEE/GPIB interface for automated testing and multi-device control. LabVIEW drivers are available for configured mainframe and module combinations.
