产品名称：OE3001原装国产光学斩波器/OE3001 optical chopper

      The OE3001 optical chopper is precision optical equipment that with the PID technology to drive motor, and provides a stable reference output signal. The OE3001 is composed of the main chassis, chopping machines and cable. Where the main chassis is the electronic control system. The chopping machine includes chopper seat and chopper blades and other components, to achieve chopper operation. The main chassis control motor and measure the speed via a line.

High Precision Designed

      Through a 320 * 240 pixel LCD display and the front panel photoelectric encoder operating (right knob), OE3001 can set the chopper frequent and control the motor. You can achieve all functions by rotating and pressing operation. The OE3001 blade can be changed with different slots blade that have different chopping frequency range and frequency accuracy. The standard of this product is 10 slots blade with the chopping frequent range of 20Hz ~ 1000Hz. Other suitable blades include 2 slots, 6-slot, 15-slot, 30 slots, 60 slots, 100 slots, and 5/7 slots (you can just have the blade you wanted).
