C-Series “HP” Electro-
Dynamic Shaker Systems
Historically Large Installed Base
The MB Dynamics C40HP, C90HP and C150HP
Electrodynamic Shakers comprise current deliverables in
a long history of reliable and rugged shakers earning a
well-deserved reputation for high performance, longevity,
and dependability. They build upon MB’s family of CSeries products (C10, C25, C40, C50, C60, C90, C125,
C126, C150, C200, C210, C220) with a heritage
spanning 50 years.
MB delivers turnkey vibration test systems including PCbased Win2K5 vibration and shock controllers (sine,
random, shock, time history, sine-on-random, SRS, etc.
up to 8-channels), special-purpose fixtures, head
expanders (featuring the 2424 Ultra-Stiff with no
troublesome resonances below 2250 Hz), oil-film slip
table assemblies from 400mm up to 1200mm square of
test item mounting area, horizontal moving tables with
patented flexures for extremely quiet operation yet highly
resistant to overturning moments, air-isolated common
bases for the shaker and slip table, AGREE systems for
Versatile Shakers and Amplifiers
The C-Series “HP” Shakers offer exceptionally high
acceleration levels with stiff armatures, have 50mm of
stroke (continuous duty), full performance SINE &
RANDOM tests out to 3000 Hz (usable, at reduced
levels, out to 4000 Hz), rugged armatures with no
resonances below 2000 Hz, reliable for shock testing
using classical pulses (half sine, sawtooth, etc.) as well
as time history replication, force ratings from 5kN to
80kN, vertical & horizontal operation, direct-coupled,
automatic payload recentering, and trunnion isolation.
M-Series Power Amplifiers drive C-Series shakers.
Amps are air-cooled, pulse width modulated using
MOSFET technology, 85-90% efficient, 125 and 250
VRMS output, peak currents of 3X continuous-duty, 6
kVA power modules, usable bandwidth from DC – 5000
Hz, 1% distortion, dissipate < 700 BTU/hr per kVA of
output power, direct coupled, 19” racks, integral shaker
field supply, control panel with normal indicators and
interlocks, and reliable.
combined environmental and vibration testing, data
acquisition hardware & software, and vibration and
acoustic instrumentation and signal conditioning.
Whether in a small or large lab, an MB vibration test
system is the preferred choice for busy people on limited
budgets. Combine that with MB’s applications

and you have
an “HP”
system that

superior
performance
for many
years to
come.
