Precision ±5V Power Supply for Photonics Lab (PS-5-M)

Data Sheet

Product Overview

The Optilab PS-5-M is a ±5V DC power supply for photonics lab with integrated RS233 and USB communication interface. It is compatible with most Optilab module products requiring ±5V DC power, such as lightwave transmitter modules and wavelength tunable laser modules. PS-5-M can transform 85V - 264V wide AC voltage into ±5V DC voltage within less than 2% ripple and output via a DB-15 connector and an extra 4-pin connector as the DC output terminal. The DB-9 or USB connector provides easy communication connection to control the functions of the target module. PS-5-M also can be used as a general 5 VDC power supply for photonics modules.
