Compact LD Driver

This product can control the current drive and temperature of 14-pin butterfly package LD modules with only the main unit. The substrate is equipped with an LCD monitor, an LD ON/OFF button and a rotary encoder for each parameter setting. A USB port, which can externally control PC, is also included on the substrate.
In addition, this product is compatible with most manufacturers' LD modules by exchanging the attached slave boards.
Capability: LD Current: 0-500 mA (Setting Resolution: 1mA, Measurement Resolution: 0.1 mA), TEC Current: 0 to }1.5 A (Measurement Resolution: 1 mA), Temperature: 15-35 deg C (Setting Resolution: 0.1 deg C, Measurement Resolution: 0.001 deg C)
Furthermore, this product has other capabilities, such as LD/TEC current limit settings, PID gain, integration coefficient settings and an alarm function.
With a built-in power supply, the product is powered and ready for use once it is plugged in via the accessory AC adapter.
