ATLS212DLD1.0 Dummy Laser Load Assembly for ATLSxA212D Series Laser Drivers

The ATLS212DLD1.0 is a dummy laser load assembly designed to emulate laser diodes for evaluating ATLSxA212D series PWM laser drivers. It provides a durable and configurable load for testing laser drivers before connecting expensive real laser diodes.

This load assembly is designed for use with ATLS50MA212D, ATLS500MA212D, ATLS1A212D, ATLS2A212D, ATLS3A212D, and ATLS5A212D laser drivers. These drivers are used for driving one or multiple laser diodes with high efficiency and low noise in DPSSL, EDFA, and fiber laser applications.

The ATLS212DLD1.0 can be used together with the ATLS212EV1.0 evaluation board or used alone as a dummy laser load. It emulates the non-linearity of laser diodes and allows users to evaluate laser driver performance without risking damage to real laser diodes during initial setup, wiring, or current adjustment.

The dummy laser uses durable regular diodes and supports high continuous and pulse current capability. It provides variable voltage drop steps from 0.88 V to 14.08 V at 3 A, allowing users to emulate one or multiple laser diodes under different forward-voltage conditions.

The ATLS212DLD1.0 includes configuration switches for selecting different diode combinations, a heat sink and fan for cooling, a fan control circuit for constant fan speed over a wide input voltage range, and an over-temperature shutdown circuit to protect the diodes when the diode temperature exceeds 90°C. The ATLS212DLD1.0 is 100% lead (Pb)-free and RoHS compliant.
