Electronic Muscle Stimulator

The AMS-4 EMS is a battery operated pulse generator that sends electrical impulses through electrodes to the body and reaches the underlying nerves or muscle group. The device is provided with two controllable output channels, each independent of each other. An electrode pair can be connected to each output channel.

The electronics of the AMS-4 EMS create electrical impulses whose Intensity, Pulse Width, Pulse Rate, Contraction, Relaxation and Ramp may be altered with the switches. Dial controls are very easy to use and the slide cover prevents accidental changes in the setting.

  • Intensity control is adjustable from 0-80 mA, 500 ohm load.
  • Pulse rate is adjustable from 2-150 Hz.
  • Dual isolated channels.
  • Pulse width is selectable: 100, 200, or 300 micro-seconds.
  • Contraction time is adjustable from 2-30 seconds.
  • Relaxation time is adjustable from 1-30 seconds.
  • Ramp time is adjustable from 1-6 seconds.
