LW126.138-13

Overview

The LW126.138-13 system offers the maximum force available from the light-weight armature ET-126 shaker without forced air cooling. It is a compact desktop system suited for general purpose testing of small transducers as well as electrical and mechanical assemblies. The ET-126 also satisfies most high frequency test requirements with operation up to 8,500 Hz and provides a voltage-proportional-to-output-current output signal for modal test and other applications requiring force monitoring. System components include ET-126-1 Electrodynamic Shaker, PA-138 Linear Power Amplifier, and interconnect cables and hoses. System options listed are SC-121 Sine Servo Controller, SG-135 Manual Sine Controller, Rack Cabinet, Accelerometer Package, and CB-152 Cooling Vacuum (>13 lbf). Performance specifications include Sine force: 13 lbs force pk; Random force: 8.0 lbf rms random; Shock force: 21 lbf pk shock. Frequency Range: DC to 8,500 Hz. Maximum Acceleration: 65 g pk, bare table; 32 g pk, 0.2 lb. load; 11 g pk, 1 lb. load. Maximum Displacement: 0.75 inch pk-pk, bare table. Cooling: Amplifier: forced air; Shaker: natural convection. Power Requirements: 1,000 VA @ 100, 110, 200, 220, or 240V, single phase 50/60 Hz. The system is perfectly suited for general purpose testing of small transducers as well as electrical and mechanical assemblies. It provides a voltage-proportional-to-output-current output signal for modal test and other applications requiring force monitoring. With operation up to 8,500 Hz and a combination of high acceleration, high frequency range, and high force, it supports medium acceleration level testing with desktop convenience.
