3.2) Power Requirements

DYN-IS-40 has an external power amplifier which is powered by its power
adaptor. Please note the output voltage and current ratings of the adaptor if
a replacement adaptor is to be used.

3.3) Cooling

DYN-IS-40 does not require forced cooling. Air convection cooling is
sufficient for the force levels given in the specifications.

3.4) Frequency Response

The DYN-IS-40 has a relatively flat force response of 40N. The following
figure shows the Force (Newton) over applied Voltage (Volt) frequency
response of DYN-IS-40.
FOR FIXED FREQUENCY SINE TESTING, APPLICATION OF VOLTAGE
LEVELS
ABOVE
1V
FOR
LONG
DURATIONS
(>1MIN)
CAN
PERMANENTLY DAMAGE THE SHAKER.
THE SHAKER SUSPENSION NATURAL FREQUENCY IS ABOUT 40 HZ.
ESPECIALLY FOR FIXED FREQUENCY SINE TESTING, THE USER
SHOULD ALWAYS LOWER THE GAIN FOR THE FREQUENCY BAND OF
5-50 HZ. OTHERWISE, DUE TO THE HIGH RESPONSE OF THE SHAKER
AROUND ITS RESONANCE FREQUENCY, VERY HIGH AMPLITUDES OF
VIBRATION (⁓120N) WILL OCCUR AND PERMANENTLY DAMAGE THE
SHAKER.
THE INTERNAL SINE SIGNAL GENERATOR SUPPLIES A CONSTANT
VOLTAGE OF 1VAC. PLEASE LOWER THE GAIN IN THE VICINITY OF
THE NATURAL FREQUENCY AS HIGHLIGHTED ABOVE.
